Research-Grade Compound

NAD+ (nicotinamide adenine dinucleotide, oxidized form) is a dinucleotide coenzyme — not a peptide — composed of an adenosine monophosphate unit joined to nicotinamide mononucleotide through a phosphoanhydride bond. Molecular formula C21H27N7O14P2, molecular weight 663.4 Da, CAS 53-84-9. It contains no amino acids and no peptide bonds, and it is listed alongside research peptides here only because the metabolic questions it answers overlap with theirs.

Purity standard: NAD+ is sourced to ≥99% by HPLC — sourcing spec. That is the specification every batch must meet, not a measurement of any one vial — the measured figure for a batch is on that batch's Certificate of Analysis.

Buying NAD+ — Frequently Asked Questions

What purity standard does Peptide.Express use for NAD+?

≥99% by HPLC with LC-MS/MS confirming the 663.4 Da mass. The relevant impurities for a dinucleotide are its own hydrolysis products — nicotinamide mononucleotide and free nicotinamide — so the chromatogram is informative about how the material has been stored, not only about how it was made.

Where is the Certificate of Analysis for NAD+?

On this page and in the Peptide.Express lab results library, keyed to the batch number on the vial. Each CoA lists HPLC purity, LC-MS/MS identity confirmation, endotoxin result, testing laboratory and test date.

How should NAD+ solution be handled — is it stable?

It is not, relative to peptides, and this is the single most useful practical fact on this page. Reconstituted NAD+ should be used within 24–48 hours, against the 14–28 days a reconstituted peptide solution typically allows. Degradation proceeds at the glycosidic and pyrophosphate bonds and accelerates markedly above neutral pH. Keep it cold, keep it near neutral, protect it from light, and prepare it fresh rather than working from a stored stock.
