NAD+

NAD+ (nicotinamide adenine dinucleotide, oxidized form) is offered strictly as a research-use-only laboratory reference material. It is not a drug, dietary supplement, cosmetic, or food ingredient, and it is not intended for human or veterinary use, injection, or ingestion. The material is supplied for analytical, chromatographic, and characterization work in qualified laboratory settings.

Structurally, NAD+ is a pyridine dinucleotide comprising a nicotinamide riboside moiety linked via a pyrophosphate bridge to an adenosine ribonucleoside, giving the empirical molecular formula C21H27N7O14P2 and a molecular weight of 663.43 g/mol (monoisotopic mass 664.1169 Da). The compound is indexed under CAS Number 53-84-9 and PubChem CID 5893, with canonical SMILES C1=CC(=C[N+](=C1)C2C(C(C(O2)COP(=O)(O)OP(=O)(O)OCC3C(C(C(O3)N4C=NC5=C(N=CN=C54)N)O)O)O)O)C(=O)N and InChIKey BAWFJGJZGIEFAR-NNYOXOHSSA-O, providing unambiguous identifiers for cross-referencing across chemical databases and internal LIMS records.

Physically, NAD+ is presented as a synthetic, lyophilized white to off-white powder. Purity is not less than 98% as determined by HPLC, with identity and lot-specific analytical data documented on the Certificate of Analysis available on request. The quaternary pyridinium nitrogen on the nicotinamide ring is responsible for the permanent positive charge that formally designates the oxidized "NAD+" state and distinguishes it chromatographically and spectroscopically from the reduced NADH counterpart, a useful reference point when developing UV, MS, or ion-pair reversed-phase HPLC methods.

This reference material is well suited to method development, standard curve preparation, retention-time and mass-spectral confirmation, and comparative characterization of pyridine nucleotide analytes in fit-for-purpose laboratory workflows. These statements have not been evaluated by the Food and Drug Administration; NAD+ supplied under this catalog listing is not intended to diagnose, treat, cure, or prevent any disease.

Supplied as a lyophilized (freeze-dried) powder in a sealed vial. A research reference material - not a finished product and not a delivery device. Net contents per unit are shown in the product options.

Store the sealed lyophilized powder at -20 C, protected from light and moisture. After reconstitution for laboratory use, keep cold and use promptly. Handle per standard laboratory practice; a Safety Data Sheet (SDS) is available on request.

This material is sold as a dietary reference material for lawful use only. By purchasing, you confirm you are 21 or older and will handle and use it in compliance with all applicable laws. These statements have not been evaluated by the Food and Drug Administration.
