PubChem CID 5893 is titled Nadide and lists NAD+ among its synonyms. The record states the formula C21H28N7O14P2+ and a molecular weight of 664.4 g/mol. A catalog figure in milligrams is a different statement.
PubChem CID 5893 is titled Nadide (JAN/USAN/INN). The synonym list includes NAD(+), Nicotinamide adenine dinucleotide (NAD+) and CHEBI:15846. ChEBI CHEBI:15846 is named NAD+.
The catalog writes the name NAD+. That is the catalog spelling of the same designation. A spelling is not a complete material identification. Connect it to the product name and to documents that are actually published for that entry.
PubChem states the formula C21H28N7O14P2+ and a molecular weight of 664.4 g/mol. The synonym calls the same record nicotinamide adenine dinucleotide. Dinucleotide is a structure class. Coenzyme, CHEBI:23354, is a role. None of those lines makes the record a peptide chain.
Those lines identify the database record. They do not state the salt form, amount or contents of a particular vial, and they are not an analysis document for a catalog product.
The catalog has one entry named NAD+. The listed variants are 500 mg and 1000 mg. Milligrams on that label are a mass for the package. PubChem’s 664.4 g/mol is the molecular weight of the database record. The two figures answer different questions and cannot be swapped.
An amount in mg is not a concentration. The quantity guide covers that difference. The database record does not make the two catalog variants the same package.
The link below goes to the NAD+ catalog entry. That page states the name, variants and price. Analytical values appear only when a document is published. The database records above do not verify the store’s material.
This guide separates a database name from a catalog label in milligrams. It does not describe dosing, preparation or use in humans or animals.
