NAD+ is the oxidised form of nicotinamide adenine dinucleotide, used as a biochemical cofactor reference in controlled laboratory workflows.
As a dinucleotide, its analytics differ noticeably from a peptide's: the two phosphate groups favour ion-pair or HILIC-based chromatography over classical peptide RP-HPLC, and detection typically relies on the nucleotide chromophore at 260 nm rather than the 214–280 nm range common for peptides. The listed formula and molecular weight (C21H28N7O14P2+, 664.4 g/mol) refer to the NAD+ cation; salt form is batch-specific.
A purity specification of ≥99% applies to NAD+; CAS number 53-84-9 serves as the unambiguous reference point, and the certificate of analysis for each batch is available for the product on request.
