B2B buyers sourcing Selank should confirm five items before comparing supplier quotes: the heptapeptide sequence reference, CAS number, purity method and threshold, LC-MS availability, and whether the supplier is quoting bulk powder or lyophilized vial format. Without these details, a low USD/g or USD/vial price may reflect an incomplete documentation package, an unconfirmed sequence, or a project scope that does not match the buyer’s requirements.
This guide is written for distributors, private label teams, OEM coordinators, and formulation consultants preparing a structured RFQ for Selank. It covers specification review, documentation requirements, format selection, MOQ and lead time considerations, red flags to watch for, and how WUMO reviews a sourcing project before issuing a formal quotation. No dosing, injection, reconstitution, or end-use guidance is included. This is a procurement reference, not a product description.
What Should Buyers Confirm First When Sourcing Selank?
Buyers should confirm that the supplier’s Selank specification matches the expected heptapeptide sequence, CAS reference, molecular formula, molecular weight, and batch documentation before requesting a price. A product name alone is not sufficient for supplier qualification at the B2B level.
Core Identity Fields
Selank is a synthetic heptapeptide referenced in research-grade B2B sourcing contexts. The CAS number commonly referenced is 129954-34-3. The sequence commonly referenced is Thr-Lys-Pro-Arg-Pro-Gly-Pro. The molecular formula commonly referenced is C₃₃H₅₇N₉O₉, with a molecular weight of approximately 751.86 g/mol. All of these fields should appear in the supplier’s specification sheet — not inferred from a catalog listing or product page.
Available B2B formats are bulk powder and lyophilized vials. Supplier documents — specification sheet, COA, HPLC report, LC-MS data, label, and packing records — must be consistent with each other and traceable to the same lot.
Why Sequence Confirmation Matters at the Inquiry Stage
Sequence confirmation at the inquiry stage removes the most common source of quote mismatch: suppliers quoting different products under the same name. For a seven-residue peptide such as Selank, LC-MS molecular weight confirmation is a standard qualification step that any competent supplier should be able to provide. A supplier that cannot supply LC-MS data for a heptapeptide should be asked to explain why before the procurement process moves forward.
The specification sheet is the anchor document for any B2B sourcing project. It should define the product — sequence, CAS, purity method, salt form, storage condition — before any price is requested. Buyers who skip this step frequently discover, after receiving three quotes, that each one references a different product scope.
Why Do Selank Sourcing Projects Stall?
Selank sourcing projects most commonly stall when buyers request price before confirming sequence, batch-specific documentation, format, fill amount, MOQ basis, and lead time scope — producing quotes that cannot be compared reliably.
This pattern is consistent regardless of buyer scale. A buyer sends an inquiry using only the product name and a rough quantity. The supplier responds with a USD/g price. A second supplier responds with a USD/vial price for an unstated fill amount. A third provides a COA without a batch number. By the time the buyer tries to compare these three responses, the gaps are too wide to close without restarting the qualification process.
Common stall points to resolve before issuing any RFQ:
- Product name quoted without sequence confirmation from a specification sheet
- CAS reference missing or inconsistent across COA, label, and specification sheet
- COA provided without a batch number — no lot traceability
- HPLC purity stated without a chromatogram or method parameters
- LC-MS not available, or not linked to the same batch as the COA
- USD/vial quote issued without a stated fill amount per vial
- MOQ stated as a single number without clarifying stock vs production basis
- Lead time given as a total figure without separating production, QC, documentation, and dispatch
- Documentation available only after payment — no pre-order review window
- Supplier issues an automatic quote without reviewing the buyer’s specification
What Naming, Sequence, and CAS Issues Should Buyers Clarify?
The key naming issue for Selank is that the product is encountered in supplier catalogs under the name Selank alone, without consistent sequence or CAS anchoring across documents. Buyers should confirm that the supplier’s specification sheet explicitly lists the heptapeptide sequence and the CAS reference — not just the product name — before accepting any quotation.
Naming and Sequence Checklist
- Confirm the supplier uses “Selank” consistently across specification sheet, COA, label, and packing records
- Confirm that the sequence Thr-Lys-Pro-Arg-Pro-Gly-Pro is listed explicitly in the specification sheet
- Confirm CAS number 129954-34-3 against the supplier’s specification document
- Confirm molecular formula C₃₃H₅₇N₉O₉ and molecular weight approximately 751.86 g/mol
- Confirm whether a salt form or counterion is applicable and disclosed
- Confirm that naming and batch identity are consistent across all documents in the package
Why Naming Consistency Matters Across Documents
A COA that references a product name without a sequence or CAS anchor creates a traceability gap at every downstream handoff — internal QC review, import review, reorder management. An RFQ that states both the product name and the sequence reference gives the supplier clear instructions for document preparation and ensures that the quotation can be traced to a defined specification. Buyers should not accept a quote where the only identifier is a catalog name.
What Specification Fields Should Every Selank Buyer Review?
Before issuing an RFQ for Selank, buyers should review ten core specification fields: product name, sequence, CAS reference, molecular formula, molecular weight, purity method and threshold, salt form, appearance, storage condition, and shelf life. Missing any of these fields increases the risk of comparing quotes that do not reflect equivalent products or documentation scopes.
Core Specification Fields
| Specification Field | What Buyers Should Confirm |
|---|---|
| Product name | Selank, consistently used across all supplier documents |
| Sequence | Thr-Lys-Pro-Arg-Pro-Gly-Pro, confirmed in specification sheet |
| CAS reference | 129954-34-3, confirmed against supplier specification |
| Molecular formula | C₃₃H₅₇N₉O₉, or supplier-documented equivalent |
| Molecular weight | ~751.86 g/mol theoretical; observed mass confirmed via LC-MS |
| Purity | HPLC area%; buyer-defined threshold stated in RFQ |
| Salt form / counterion | Confirm whether applicable; disclosed in specification sheet |
| Appearance | White to off-white lyophilized powder, or per supplier standard |
| Storage condition | Supplier-defined temperature, humidity, and light requirements |
| Shelf life / retest date | Lot-specific statement or supplier-standard shelf life |
Salt Form and Its Relevance to Fill Weight
Salt form disclosure matters most in lyophilized vial projects. When a buyer specifies a fill amount in mg per vial, the net peptide content depends on whether the stated weight includes the counterion mass. An undisclosed salt form makes accurate fill weight calculation impossible and introduces an error that compounds at scale. Any supplier quoting a vial format for Selank without disclosing salt form has left a specification gap that must be resolved before the quotation can be used for project planning.
What Documents Should Buyers Request Before Comparing Selank Quotes?
Buyers should request five documents before comparing Selank supplier quotes: COA, HPLC report, LC-MS report, SDS, and the supplier’s specification sheet. Each document confirms a different aspect of product identity, purity, and handling — and all five should be reviewed before a formal RFQ is issued.
Document Review Table
| Document | What It Confirms | When to Request | Why It Matters for Selank |
|---|---|---|---|
| COA | Batch identity, purity, appearance, test results | At qualification stage, before RFQ | Confirms lot-level data and traceability |
| HPLC report | Purity by chromatographic method; area% | Together with COA | Supports purity figure with method detail |
| LC-MS report | Molecular weight and sequence identity support | Before final supplier comparison | Standard check for a seven-residue peptide |
| SDS | Handling, storage, and transport classification | Before any shipment discussion | Required for freight and customs planning |
| Specification sheet | Supplier’s defined product standard | Before quote comparison begins | Establishes sequence, CAS, and what is being quoted |
What Documentation Does Not Guarantee
The COA confirms lot-specific test results — it does not confirm import eligibility in the buyer’s market. The HPLC report confirms purity by chromatographic method — it does not confirm sequence identity. The LC-MS report supports molecular weight confirmation — it is not a regulatory filing. The SDS supports handling and transport planning — it does not confirm purity or product identity. No document in this package guarantees import clearance or regulatory approval in any jurisdiction. Buyers are responsible for evaluating the applicable requirements in their target market independently.
Practical standards for each document:
- COA must be batch-specific with a lot number — a generic template is not acceptable
- HPLC report should include the chromatogram and method parameters, not just the purity percentage
- LC-MS should be linked to the same batch as the COA wherever possible
- Specification sheet should be reviewed before quotation, not requested after payment
What Red Flags Suggest a Selank Supplier Is Not Ready for B2B Projects?
The most serious red flags in Selank sourcing are: no sequence listed in the specification sheet, COA without a batch number, purity claim without HPLC support, LC-MS unavailable without explanation, USD/vial quote without a fill amount, and a quotation issued before the supplier has reviewed the buyer’s specification.
Red Flag Assessment Table
| Red Flag | Why It Matters | Buyer Action |
|---|---|---|
| Sequence not listed in specification sheet | Product identity is unconfirmed | Request sequence confirmation in writing |
| COA has no batch number | No lot traceability; cannot link to test records | Request a batch-linked COA before proceeding |
| HPLC purity stated without chromatogram | Purity figure cannot be independently reviewed | Request full HPLC report with method details |
| LC-MS unavailable without explanation | Molecular weight and identity review is incomplete | Ask directly; evaluate the supplier’s response |
| Salt form not disclosed | Fill weight calculations are unreliable for vial projects | Require disclosure before any vial quotation |
| USD/vial quote issued without fill amount | Price per vial cannot be normalized for comparison | Request fill amount in mg/vial before comparing |
| MOQ stated verbally only | No documented batch basis for project planning | Request written MOQ confirmation with basis |
| Lead time given as a single number | Scope is unclear; risk of underestimate | Ask for a stage-by-stage breakdown |
| Documents available only after payment | No pre-order review window for the buyer | Request representative documents at qualification |
| Supplier auto-quotes without specification review | Project fit and product identity not being checked | Ask the supplier to confirm specification review |
Red flags do not automatically disqualify a supplier — some gaps reflect process limitations that can be discussed. What matters is the quality of the supplier’s response when each gap is raised. A supplier that cannot address these questions clearly during qualification is unlikely to support a structured procurement process effectively.
Should Buyers Choose Bulk Powder or Lyophilized Vial Format?
Bulk powder is more appropriate when the buyer needs downstream processing flexibility, reformulation, or repackaging. Lyophilized vial format is more appropriate when the project requires a defined, shelf-ready unit for distribution, private label, or OEM delivery. The two formats involve different MOQ structures, lead times, documentation scopes, and specification priorities and should not be compared as equivalent options without separating these dimensions.
Format Comparison Table
| Factor | Bulk Powder | Lyophilized Vial |
|---|---|---|
| Typical buyer | Distributor, formulator, repackager | Private label, OEM, distribution-ready project |
| Quote unit | USD/g or USD/mg | USD/vial or USD/box |
| MOQ basis | Gram quantity or production batch size | Vial count, box count, or fill batch minimum |
| Key specification priority | Sequence, purity, salt form, net packaging weight | Fill amount, vial size, stopper type, label format |
| Lead time | Shorter when stock is available | Longer due to fill-and-finish scheduling |
| Documentation | COA, HPLC, LC-MS, SDS, specification sheet | Core documents plus fill batch records and packaging details |
| Custom options | Container size, packaging format, desiccant | Fill amount, vial configuration, label format, box count |
| Shipment planning | Storage condition, packaging type, cold chain | Vial packaging, box format, cold chain, freight planning |
Custom Fill Considerations for Selank Vials
Custom fill projects for Selank — where the buyer specifies a non-standard fill amount or requires private label packaging — carry a higher MOQ than standard configurations and a longer lead time. The salt form must be confirmed before fill weight calculations are possible. A buyer entering a custom fill discussion without knowing the salt form will receive fill weight estimates that may be inaccurate by a margin that matters at the vial level. Label artwork review and approval adds further time to the production schedule and should be factored into project planning before any order is committed.
For a detailed guide on lyophilized vial specification, fill amount, packaging, and MOQ, see Lyophilized Peptide Vial Sourcing: Fill Amount, Packaging, MOQ, and Documentation.
What Do MOQ and Lead Time Actually Mean for Selank Projects?
MOQ and lead time for Selank sourcing depend on stock status, format, batch size, documentation scope, and whether the project involves custom filling or private label packaging. Buyers should confirm both in writing before accepting a quotation — verbal or chat-based estimates are not reliable for project planning at any scale.
MOQ and Lead Time Matrix
| Scenario | MOQ Basis | Lead Time Factor | Key Confirmation Needed |
|---|---|---|---|
| Bulk powder, in stock | Per gram or available lot quantity | Shorter | Confirm available quantity and retest date |
| Bulk powder, production required | Minimum production batch size | Longer | Confirm synthesis schedule and QC timeline |
| Standard lyophilized vial | Vial count or fill batch minimum | Moderate to long | Confirm fill schedule availability |
| Custom fill, standard label | Fill batch minimum | Long | Confirm fill amount, vial format, batch commitment |
| Custom fill, private label | Fill batch minimum plus packaging scope | Longest | Confirm label artwork approval process and timeline |
What MOQ Actually Means
MOQ is not a single standardized figure. Depending on the supplier, it may refer to the minimum order at a given price point, the minimum that triggers a production run, the minimum fill batch for vial format, or the minimum order value for a particular buyer category. When a supplier states an MOQ, buyers should ask directly: does this refer to a stock order, a production batch, or a custom fill batch minimum? Each scenario has different planning implications and different lead time assumptions attached to it.
What Lead Time Actually Includes
Lead time for Selank bulk powder includes synthesis, purification, QC testing, documentation preparation, and export packing. For lyophilized vials, add fill-and-finish scheduling, secondary packaging, and — for custom or private label orders — label artwork review and approval. Freight transit time from the supplier’s location to the buyer’s destination is entirely separate from production lead time. Buyers who plan only against the production figure, without accounting for freight, frequently miss their own project deadlines.
For a broader discussion of MOQ and lead time factors across peptide formats, see Bulk Peptide Purchasing Guide: MOQ, Lead Time, and Cost Considerations.
How Should Buyers Prepare a Stronger RFQ for Selank?
A stronger Selank RFQ defines sequence, CAS reference, format, fill amount if vials are needed, purity threshold and method, required documents, MOQ range, destination, and quote unit before the supplier responds. This prevents suppliers from quoting against their own default assumptions and makes quote comparison reliable.
The most common failure in Selank RFQs is not missing information — it is leaving key fields unstated. When the buyer does not specify purity threshold, the supplier assumes a minimum. When the buyer does not specify salt form for a vial project, the fill weight calculation may be wrong. When the buyer does not state fill amount, the USD/vial figure from three different suppliers reflects three different product scopes. None of these gaps are difficult to close — they require the buyer to resolve them before sending the RFQ, not after receiving a price that cannot be compared.
RFQ Field Checklist
| RFQ Field | Why It Matters |
|---|---|
| Product name | Confirms the buyer is requesting Selank specifically |
| Sequence reference | Confirms Thr-Lys-Pro-Arg-Pro-Gly-Pro identity |
| CAS reference | Supports supplier document matching against 129954-34-3 |
| Format: bulk powder or lyophilized vial | Determines MOQ structure, quote unit, and lead time basis |
| Fill amount if vials are requested | Required to normalize USD/vial comparisons across suppliers |
| Purity threshold and test method | Enables comparable quote review |
| Required documents | Sets expectations: COA, HPLC, LC-MS, SDS, specification sheet |
| Target MOQ and acceptable range | Filters out suppliers whose batch minimum does not match project scale |
| Destination country or region | Affects SDS version, label language, and freight planning |
| Project timeline | Allows supplier to confirm feasibility before quoting |
| Quote unit preference | Avoids USD/g vs USD/vial mismatch in comparison |
For a detailed breakdown of quote unit structures across peptide projects, see Peptide Quote Units: USD/g vs Vial vs Box.
What Supplier Qualification Checkpoints Apply to Selank Projects?
A qualified Selank supplier should confirm sequence, CAS reference, documentation scope, MOQ basis, lead time, and batch traceability before issuing a formal quotation. A supplier that cannot define these fields during the qualification stage is not ready for final vendor comparison.
Qualification checkpoint list:
- Supplier confirms sequence Thr-Lys-Pro-Arg-Pro-Gly-Pro and CAS 129954-34-3 from a specification sheet — not from a catalog label
- Specification sheet is available before formal quotation is issued
- Batch-specific COA is available, with lot number and test date
- HPLC chromatogram supports the stated purity result, with method parameters included
- LC-MS data is available for the heptapeptide, or the supplier provides a clear explanation of why it is not
- SDS is available at the inquiry stage, before any shipment discussion begins
- Batch number links to COA, HPLC, LC-MS, and all associated test records
- MOQ is confirmed in writing with clear basis: stock quantity, production batch, or vial fill batch
- Lead time is stated with production vs stock basis, and QC and documentation stages noted separately
- Supplier reviews buyer specification before quoting — not a catalog auto-quote
- Custom fill or private label capability confirmed in advance if the project requires it

What Does WUMO Review Before Issuing a Formal Quotation?
WUMO reviews product identity, documentation availability, MOQ feasibility, quote unit basis, and project fit before issuing a formal Selank quotation. No auto-generated quotes are issued for specification-sensitive projects. A useful quotation starts with confirmed product definition — sequence, CAS, format, and documentation scope — not a catalog price.
Product identity and specification alignment
WUMO confirms that the buyer’s stated sequence reference, CAS number, and format match the available sourcing specification before any price discussion begins. If the buyer’s inquiry is ambiguous on sequence, salt form, or format, WUMO raises these questions before quoting — not after a price has been issued.
Documentation availability
WUMO verifies which documents are available for the relevant lot or batch: COA, HPLC, LC-MS, SDS, and specification sheet. For Selank, LC-MS availability is reviewed as a standard checkpoint. If documentation gaps exist, they are communicated to the buyer as part of the sourcing discussion before quotation is issued.
MOQ and quantity feasibility
WUMO reviews whether the buyer’s target quantity aligns with minimum batch requirements for the requested format. For vial-format projects, this includes confirming fill amount, vial configuration, and whether the requested specification is within available fill capacity.
Quote unit alignment
Before issuing a formal quotation, WUMO confirms whether the buyer needs pricing in USD/g, USD/vial, or USD/box. Mixing quote units across a supplier comparison set produces unreliable results. Aligning on unit basis at the inquiry stage prevents this.
Project fit and custom fill scope
For buyers requesting custom fill amounts, private label packaging, or non-standard configurations, WUMO reviews the full project scope — fill amount, vial format, label requirements, destination, and timeline — before committing to a formal quotation. Custom projects that are not scoped in advance consistently encounter MOQ, lead time, or documentation issues that delay final ordering.
How Does WUMO Support Qualified Selank B2B Sourcing Projects?

Frequently Asked Questions
What is the CAS number for Selank and how do I confirm it with a supplier?
The CAS number commonly referenced for Selank is 129954-34-3. To confirm it with a supplier, request the product’s specification sheet and verify that the CAS number appears consistently across the specification sheet, COA, and LC-MS data. A supplier that cannot provide a specification sheet with a confirmed CAS reference at the inquiry stage has not completed the documentation preparation required for B2B procurement. CAS confirmation should happen before any quotation is requested, not after.
What sequence should buyers confirm when sourcing Selank?
The sequence commonly referenced for Selank is Thr-Lys-Pro-Arg-Pro-Gly-Pro — a synthetic heptapeptide. Buyers should request that this sequence be listed explicitly in the supplier’s specification sheet, not inferred from a product name or catalog label. Including both the product name and the sequence reference in the RFQ ensures the supplier quotes against the correct specification and prepares documents with consistent product identity across the full package.
What documentation should I request before issuing an RFQ for Selank?
Request five documents at the qualification stage: COA (batch-specific, with lot number), HPLC report (with chromatogram and method details), LC-MS report, SDS, and the supplier’s specification sheet. All five should be reviewed before comparing quotes. A missing document — particularly LC-MS for a heptapeptide — is a qualification gap, not an administrative detail. Buyers who request documents only after receiving a price lose their pre-order review window and frequently encounter specification issues that require restarting supplier evaluation.
Why is LC-MS important for Selank supplier qualification?
LC-MS confirms the observed molecular weight of the peptide, providing an independent identity check beyond the HPLC purity figure. For Selank — a seven-residue synthetic heptapeptide — LC-MS data should be readily available from a qualified supplier. HPLC confirms purity by chromatographic method but does not confirm correct sequence assembly. If a supplier cannot supply LC-MS for Selank without explanation, buyers should ask directly why it is unavailable before proceeding with supplier qualification.
What is the difference between bulk powder and lyophilized vial format for Selank?
Bulk powder is quoted in USD/g and suits buyers who need downstream processing flexibility, reformulation, or repackaging capability. Lyophilized vials are quoted in USD/vial or USD/box and are more appropriate for distribution-ready, private label, or OEM projects. The two formats involve different MOQ structures, lead times, documentation scopes, and specification requirements. Comparing them directly without separating these dimensions produces cost comparisons that cannot be used for reliable project planning.
How should I compare USD/g and USD/vial quotes for Selank?
To compare USD/g and USD/vial quotes meaningfully, buyers need to know the fill amount per vial in mg, the vial count per box, the net peptide content per unit, and whether filling, packaging, and labeling costs are included in the unit price. A USD/vial quote without a stated fill amount cannot be normalized or compared against any other quote. Request these details from every supplier before attempting a cost comparison. See also Peptide Quote Units: USD/g vs Vial vs Box.
What fill amount should I specify for Selank lyophilized vial sourcing?
The appropriate fill amount per vial depends on the buyer’s intended product configuration and downstream distribution format. When issuing an RFQ for lyophilized vials, buyers should specify their target fill amount in mg per vial explicitly. The supplier can then confirm feasibility, advise on the appropriate vial size, and calculate fill weight based on the confirmed salt form. Leaving fill amount unstated in the RFQ results in a quotation that cannot be used for project planning or meaningful cost comparison across suppliers.
What is a realistic MOQ for Selank sourcing projects?
MOQ for Selank depends on format, stock availability, and whether the project involves custom fill or private label packaging. Bulk powder MOQ is typically defined by batch weight or available stock. Lyophilized vial MOQ is set by the minimum fill batch, which is determined by fill equipment capacity. Custom configurations carry higher MOQ than standard formats. Buyers should request written MOQ confirmation that specifies whether the figure refers to a stock order, a production batch, or a fill batch minimum — these are materially different planning scenarios.
What are the most common red flags when evaluating Selank suppliers?
The most common red flags are: sequence not listed in the specification sheet, COA without a batch number, purity figure stated without an HPLC chromatogram, salt form undisclosed for a vial project, LC-MS unavailable for a heptapeptide without explanation, USD/vial quote without a fill amount, MOQ stated verbally with no written confirmation, lead time given as a single number without scope, and documentation offered only after payment. Buyers should treat each gap as a question to raise and evaluate the quality of the supplier’s response before proceeding.
What should a stronger Selank RFQ include?
A stronger RFQ should state: product name and sequence reference (Thr-Lys-Pro-Arg-Pro-Gly-Pro), CAS number (129954-34-3), requested format (bulk powder or lyophilized vial), fill amount if vials are needed, purity threshold and preferred test method, required documentation package (COA, HPLC, LC-MS, SDS, specification sheet), target MOQ and acceptable range, destination country or region, project timeline, and preferred quote unit. Providing these fields prevents suppliers from quoting against their own defaults and makes the resulting quotes comparable.
Does COA and HPLC documentation guarantee import clearance for Selank?
No. COA and HPLC documentation confirm product specification at the point of testing. They do not guarantee import clearance, regulatory approval, or end-use authorization in any jurisdiction. Import eligibility depends on the regulatory requirements of the destination market, the buyer’s applicable licenses or registrations, and the classification of the product under local rules. Buyers are responsible for evaluating regulatory applicability in their target market independently of the documentation review process.
How does WUMO review Selank sourcing projects before issuing a quotation?
WUMO reviews five areas before issuing a formal Selank quotation: product identity and specification alignment (sequence, CAS, format), documentation availability (COA, HPLC, LC-MS, SDS, specification sheet), MOQ and quantity feasibility for the requested format, quote unit basis alignment (USD/g vs USD/vial vs USD/box), and project fit including custom fill scope if applicable. No auto-generated quotes are issued for specification-sensitive projects. Each quotation follows a specification and project review. Buyers with a defined RFQ are welcome to submit a project inquiry.
If you are evaluating Selank as a B2B sourcing project, WUMO can review your specification, confirm available documentation, and discuss format options, MOQ, and project fit before issuing a formal quotation. Qualified B2B buyers are welcome to submit a project inquiry with product definition, preferred format, target quantity, quote unit, and documentation requirements. Contact WUMO to start a project discussion.
