Research Compound Reference
NAD+ Research Compound
NAD+ is nicotinamide adenine dinucleotide in its oxidised form — a dinucleotide redox coenzyme, not a peptide. This reference covers the chemical identity of the Vial Drop Labs NAD+ 1000 mg research material and how it is documented analytically.

Chemical identity — and why it is not a peptide
NAD+ is frequently listed alongside research peptides for convenience, and the classification is wrong. A peptide is a chain of amino acids joined by amide bonds. NAD+ is a dinucleotide: two nucleotides — one carrying nicotinamide, one carrying adenine — linked through a pyrophosphate bridge. There is no sequence to state, because there are no amino acids in it.
The oxidised form, NAD+, and the reduced form, NADH, are distinct chemical species with distinct masses and distinct identifiers. Documentation, reference standards and chromatographic methods for one do not transfer to the other, and salt forms (for example disodium salts) are again distinct from the free acid. Always confirm which species a document describes.
The free acid form has the molecular formula C21H27N7O14P2, an average molecular weight of approximately 663.4 g/mol, and CAS registry number 53-84-9.
Analytical methodology
Purity for NAD+ research material is typically reported by HPLC as an area-percent figure. Because NAD+ and NADH absorb differently in the ultraviolet region, chromatographic methods for this compound are informative about the oxidation state of the sample as well as its purity.
The compound is hygroscopic and is sensitive to moisture and to hydrolysis in solution, which is why lyophilised presentation and controlled storage are standard for this material.
Reading the analytical documentation
A Certificate of Analysis links a submitted sample to the analytical work performed on it. Current Vial Drop Labs reports are produced by validated HPLC-DAD methodology and answer two separate questions — what the material is, and how much of it is present.
- Identity — on current Vial Drop Labs reports, identity is reported as conforming on the basis of retention time and UV/DAD spectral comparison against a reference standard. Current reports do not include mass-spectrometry results.
- Purity — HPLC separates the dissolved sample across a column; the target peak's share of total integrated peak area is reported as an area-percent purity figure.
- Content — peptide and compound reports separately state the content per vial in mg against the stated label claim. Chromatographic purity and content per vial are two different measurements and should not be read as one.
- Sample scope — the report identifiers and test date describe the randomized sample the laboratory received and the batch it was drawn from as supplied to the laboratory. Recording the certificate ID alongside your own experimental records keeps the analytical record resolvable.
- Scope — a report describes only the specific sample submitted. Unless a report expressly states otherwise, it does not assess sterility, endotoxin, microbial content, heavy metals or residual solvents, and it is not a safety or fitness-for-use determination.
How Vial Drop publishes analytical documentation
Vial Drop Labs publishes independent analytical reports for tested research materials, with available reports accessible through the Research Documentation portal against the research material and the sample identified on each report. Each analytical report applies only to the sample submitted for analysis and should not be interpreted as testing of every vial or production unit.
Not every report is publicly listed. Where no report has been published for a material, the portal shows none rather than substituting another material's, strength's or batch's results. Documentation is never averaged, combined, or extrapolated between lots.
Current reports are issued by an independent third-party analytical laboratory using validated HPLC-DAD methodology. They report chromatographic purity as area %, content per vial against label claim, and identity as conforming by retention-time and UV/DAD comparison against a reference standard. Current reports do not include mass-spectrometry results.
Vial Drop Labs makes no representation that material is pharmaceutical grade, clinical grade, sterile, safe, or approved by any regulatory authority. Published documentation states exactly what was tested, by which method, and on which date — nothing further should be inferred from it.
Laboratory storage and handling
Material is supplied lyophilised in a sealed glass vial. Store sealed at -20 °C, protect from light and moisture, and allow a cold vial to equilibrate to ambient temperature before opening so that atmospheric moisture does not condense onto the dry solid.
Handle as a laboratory chemical using standard laboratory protective equipment and institutional handling procedures.
Research use only
This material is supplied strictly as a laboratory research chemical. It is not a drug, supplement, cosmetic, food or medical device, and it is not manufactured, labelled or sold for human or animal use of any kind.
Vial Drop Labs does not provide, and cannot provide, dosing, administration, preparation-for-use, therapeutic or clinical guidance. Published information is limited to chemical identity, laboratory handling and analytical documentation.
