NAD+ 500mg is the Pepta Labs listing for one sealed glass vial holding 500 mg of NAD+ (nicotinamide adenine dinucleotide) as lyophilized powder, sold as a laboratory reference material. The 500 mg figure is the supplier-stated quantity of dry powder per vial, and the same compound is also listed as NAD+ 1000mg. NAD+ sits in the research peptide catalog, but it is a dinucleotide rather than a peptide. The independent HPLC purity and mass spectrometry report is sent by email on request, before you order if you want it: request it on this page or email support@peptalabs.com.

NAD+ 500mg: $56.41 per vial ($0.113 per mg of the supplier-stated 500 mg). Ships to US addresses only. NAD+ 500mg (Nicotinamide Adenine Dinucleotide) is a lyophilized research compound supplied as 500mg of dry powder per sealed vial. CAS 53-84-9; molecular formula C21H27N7O14P2; molecular weight 663.43 Da.

Chemical identity

What NAD+ is

NAD+ (nicotinamide adenine dinucleotide, INN nadide, also called beta-NAD or diphosphopyridine nucleotide) is a non-peptide dinucleotide. Structurally it consists of two nucleotides, adenosine monophosphate and nicotinamide mononucleotide, joined through their phosphate groups by a pyrophosphate bridge; the nicotinamide ring carries a positive charge on the pyridinium nitrogen, hence the plus sign, and the ribose units are in the beta-D configuration. The molecular formula is C21H27N7O14P2 and the molecular weight is 663.4 g/mol (monoisotopic 663.11). It is registered under CAS 53-84-9, PubChem CID 5892 and UNII 0U46U6E8UK. As a free acid it is a hygroscopic white to off-white powder. Pepta Labs lists NAD+ as a lyophilized powder in a sealed glass vial, available as 500 mg and 1000 mg quantities, with reported HPLC purity of 99.5% and identity confirmed by mass spectrometry. Recommended storage is 2-8 C short term and -20 C long term, protected from light and moisture. It is sold strictly as a chemical reference material for laboratory research use only.

Questions

NAD+ 500mg — common questions

What NAD+ sizes does Pepta Labs sell?

Two: NAD+ 500mg (this listing) and NAD+ 1000mg. Both are the same compound, CAS 53-84-9, supplied as lyophilized powder in a sealed glass vial; they differ only in the supplier-stated quantity per vial. Each size has its own page, price and pack options.

What exactly is in a NAD+ 500mg vial?

500 mg of NAD+ as a dry, white to off-white lyophilized powder in a sealed glass vial. The 500 mg is the supplier-stated powder quantity: vial fill weight is not independently tested, and net NAD+ content (for example, residual water) is not reported per listing.

Is the NAD+ in this vial the free acid or a sodium salt?

The listing record describes the free acid, a pyridinium inner salt (zwitterion) with the formula C21H27N7O14P2 and a molecular weight of 663.43 Da. Disodium and lithium salts of NAD+ also exist and have higher formula weights, so gram for gram they contain fewer moles of NAD+. If the form matters for your work, check it on the analytical report before ordering.

How do I get the HPLC and mass spec report for NAD+ 500mg?

Request it on this page or email support@peptalabs.com with the compound name; the report is sent by email, before you order if you want to see it first. It covers the sampled production run the listing was sourced from, not an individual vial, since vials carry no lot number. Purity is reported as RP-HPLC area-percent and identity is confirmed by mass spectrometry against the calculated NAD+ mass (monoisotopic 663.11).

How should a sealed vial of NAD+ powder be stored?

Keep the sealed vial at 2-8 C for short periods and at -20 C for long-term storage, away from light and moisture. The free acid is hygroscopic, so let a cold vial reach room temperature before opening it to keep condensation off the powder.

Where can I read more about checking an NAD+ report?

The Learn guide on NAD+ (nadide) covers the free acid versus salt forms, average versus monoisotopic mass, and what the HPLC and mass spectrometry sections of a report show. The guide How to Read and Verify a Peptide Certificate of Analysis (COA) walks through each report field.

What does NAD+ 500mg cost?

NAD+ 500mg starts at $56.41 per vial. 3-vial packs are 7% off and 5-vial packs are 14% off. US shipping is free with no minimum.

What payment methods are accepted?

Pepta Labs accepts Cash App, Venmo, Zelle, Bitcoin and Ethereum (5% crypto discount). Payment instructions are emailed as soon as you place your order.

Is this for human or animal use?

No. NAD+ 500mg is offered solely for laboratory research and is not for human or animal use, consumption, administration, diagnosis or treatment. Buyers certify this at checkout.

Is NAD+ a peptide?

No. NAD+ is a dinucleotide, not a peptide: it contains no amino-acid residues or peptide bonds. It is built from adenine, nicotinamide, two ribose sugars and two phosphate groups, formula C21H27N7O14P2, 663.4 g/mol.

What is the difference between NAD+ and NADH?

NADH is the two-electron reduced form of the same dinucleotide: the nicotinamide ring gains a hydride, giving the neutral formula C21H29N7O14P2 (665.4 g/mol) and removing the pyridinium positive charge. The two forms are distinguished by UV absorbance, since NADH absorbs at 340 nm and NAD+ does not.

What does the CAS number 53-84-9 identify?

CAS 53-84-9 is the registry number for nicotinamide adenine dinucleotide in its free acid (inner salt) form. Salt forms such as the disodium or lithium salt carry their own registry numbers.
