Know your compound
What is NAD+?
NAD+ (nicotinamide adenine dinucleotide) is a coenzyme present in all living cells and central to redox reactions and energy metabolism. It is one of the most widely studied molecules in cellular biology and ageing research.
Supplied as a lyophilized powder for laboratory research use only.
- ScaffoldNicotinamide and adenine, each on a ribose, joined by a pyrophosphate bridge

Identity
What the molecule is.
- Molecular formula
- C21H27N7O14P2
- The atom count in a single molecule.
- Molecular weight
- 663.43 g/mol
- The mass of one mole. You need this figure to calculate concentration when reconstituting.
- CAS
- 53-84-9
- The registry number that identifies this substance unambiguously in chemical databases.
Verification
How we know the material matches the label.
- Purity
- ≥99% (RP-HPLC, per lot)
- The share of the material that is the target compound, measured by reverse-phase HPLC on every lot — not a blanket brand claim.
- Identity method
- LC-MS confirmed
- Mass spectrometry compares the material against the expected sequence to confirm it is the right molecule.
- Documentation
- Certificate of Analysis, per lot
- The certificate for your specific lot is published before it ships and stays searchable by lot number.
Handling
What arrives, and how it is kept.
- Form
- Lyophilized powder
- The physical state the vial arrives in.
What the literature examines
Studied pathways
Summaries of what published research has investigated. Preclinical unless stated otherwise — not claims about this product.
Enzyme cofactor
Research examines NAD+ as a substrate for sirtuins and PARPs, enzyme families studied in cellular maintenance.
Ageing research
A substantial literature examines cellular NAD+ availability in models of ageing and metabolic stress.
Certificate of Analysis
Every vial ships with its own report
Not a brand-wide spec sheet — a lot-specific certificate from an independent laboratory, published before the lot ships and searchable by lot number forever.
- Lot-specific HPLC purity and LC-MS identity
- Raw chromatogram attached to the certificate
- Signed by the analysing laboratory
- Permanent public archive, searchable by lot ID

Questions
NAD+ FAQ
Is NAD+ approved by the FDA?
No. NAD+ is not an FDA-approved drug and is not approved for human or veterinary use. It is supplied exclusively as a research material for laboratory use, and it is not intended to diagnose, treat, cure, or prevent any disease.
Does this lot come with a Certificate of Analysis?
Yes. Every lot is assayed by an independent U.S. laboratory for purity and identity, and the certificate for the lot you receive is published in our COA library — you can read it before you order.
How is purity determined?
Purity is quantified by reverse-phase HPLC against a reference standard, and identity is confirmed by mass spectrometry. Both results appear on the lot certificate.
How should this be stored?
Lyophilized material is typically stored cold and protected from light. Handling and storage are the responsibility of the receiving laboratory; refer to the lot documentation for specifics.
How does the buy-one-get-one offer work?
Every second vial is free, sitewide and automatically. Add two vials and you pay for one; add six and you pay for three. Compounds can be mixed, there is no code, and there is no limit.
When will my order ship?
Orders are processed promptly and shipped with tracking. Free US shipping applies over $100; Priority shipping is $8.95 otherwise.
