Specification and laboratory information
NAD+ 500mg is a laboratory research reagent supplied in powder form. It is a coenzyme, rather than a peptide. Review the chemical specification and confirm the document for your batch before ordering.
Laboratory and analytical research only. Not for human consumption. Orders restricted to adults aged 18 or over.
A point of accuracy first: NAD+ is not a peptide. It's a dinucleotide — two nucleosides joined through a pyrophosphate bridge — and functions as a redox coenzyme. It sits on this catalogue because it's routinely required alongside peptide work, but the chemistry, handling and analysis are quite different, and it's worth being clear about that rather than filing it under the same heading as everything else.
Supplied as β-nicotinamide adenine dinucleotide, oxidised form, as a lyophilised powder at a 500mg fill.

Storage and handling
Store sealed at −20°C, protected from moisture. NAD+ is markedly hygroscopic — water uptake is the primary cause of assay variance with this material, so keep the container desiccated, equilibrate fully to ambient temperature before opening, and reseal promptly. Water content on the COA should be read alongside the purity figure, since purity is normally calculated on the anhydrous substance.
Supply and despatch
UK tracked delivery is free. Paid orders for available stock placed before 3pm UK time on a working day are normally dispatched the same day. See our delivery information for details.
Frequently asked questions
Is NAD+ a peptide? No. It's a dinucleotide coenzyme, chemically unrelated to the peptides on this catalogue.
What is the CAS number for NAD+? 53-84-9 for the free acid. The disodium salt is registered separately — check which form your COA specifies.
What is the molecular weight? 663.43 g/mol for the free acid.
Why does the purity figure reference anhydrous substance? NAD+ is hygroscopic, so absorbed water would otherwise depress the apparent purity. Read purity and water content together on the COA.
