NAD+ (β-NAD) Raw Material Sourcing
NAD+ / β-NAD is a frequently requested non-peptide molecule in peptide-adjacent raw-material sourcing. This page helps B2B buyers review chemical identity, batch documentation, assay and purity data, storage requirements, and quotation checkpoints before issuing an RFQ or confirming a bulk order.
Identity
What NAD+ is (and what it is not)
NAD+ (β-nicotinamide adenine dinucleotide) is a coenzyme — a dinucleotide built from two nucleotides (one with an adenine base, one with nicotinamide) joined through their phosphate groups. It is not a peptide and is not produced by peptide synthesis; we list it because buyers sourcing peptide raw materials routinely ask for it in the same order.

Verify before you order
Documents and checks
- Identity — confirm CAS 53-84-9 and the molecular formula on the COA.
- Purity — HPLC result plus the chromatogram for the quoted batch.
- Real content — ask for actual assay, not only purity %. Purity vs content →
- Analytical method — so the result can be reproduced. How to read a COA / HPLC / MS →
- Storage & shelf life — confirmed on the COA (NAD+ is hygroscopic and heat/moisture sensitive).
Practical sourcing
Storage, packaging, MOQ
Storage: keep sealed, dry and cold (refrigerated or frozen for longer holding). The dry powder usually tolerates short ambient transport, but plan packaging and confirm conditions on the COA.
Commercial: confirm MOQ, lead time, packaging unit and batch documentation up front. For evaluation, request a small sample with its batch COA before committing to bulk.
FAQ
Common buyer questions
Is NAD+ a peptide?
No. NAD+ (β-nicotinamide adenine dinucleotide, CAS 53-84-9) is a coenzyme — a dinucleotide formed from two nucleotides joined by their phosphate groups. It is not a peptide and is not made by peptide synthesis. We list it because buyers sourcing peptide raw materials frequently ask for it alongside their peptide orders.
How do I verify NAD+ quality before ordering?
Request a batch-specific COA with the HPLC purity result and the chromatogram, confirm identity against CAS 53-84-9 and the molecular formula, and ask for the analytical method so the result can be reproduced. See our guides on purity vs content and how to read a COA / HPLC / MS report.
How should NAD+ be stored and shipped?
NAD+ powder is hygroscopic and heat/moisture sensitive. It is typically kept sealed, dry, and cold (refrigerated or frozen for longer storage); short transport at ambient temperature is usually acceptable for the powder, but confirm storage conditions and shelf life on the COA and plan packaging accordingly.
What is the regulatory status of NAD+ and NMN?
NAD+ raw material is widely supplied for research and ingredient use; it is not a peptide drug. Its precursor NMN has had a shifting US status: the FDA excluded it from the dietary-supplement definition in 2022, then reversed that position in 2025 — NMN is no longer excluded, though it remains a New Dietary Ingredient that requires premarket notification. Regulatory treatment differs by molecule, market, and intended use, so confirm the status that applies to your application before purchasing.
