NAD+ is a research-grade compound supplied strictly for laboratory research use. This page describes what the compound is and how each lot is characterized — reference information about identity, classification, and analytical testing, with no claim about any effect or application.
Identity and classification
NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in all living cells — a dinucleotide composed of nicotinamide and adenine nucleotides. It is a central carrier in cellular redox (electron-transfer) reactions and is studied in laboratory research in the context of cellular metabolism, including sirtuin- and PARP-related pathways.
How each lot is tested
Every batch is analyzed by an independent, ISO/IEC 17025-accredited U.S. laboratory. Identity is confirmed by mass spectrometry against the expected molecular weight, and purity is measured by HPLC-UV and reported per lot. See our Lab Testing & Analytical Methodology page for the full method.
Format and handling
Supplied as a lyophilized powder in a sealed vial and intended to be handled only by qualified professionals in an appropriate laboratory setting.
Documentation
Each lot ships with its own certificate of analysis. Review the certificates on our Lab Reports page, learn how to read a COA, and confirm a specific vial by its lot number on the Verify a Lot page. Browse the catalogue on our Shop page.
