Research compound library

What each compound is, in checkable terms: sequence, molecular formula, molar mass and registry numbers, read from PubChem, plus what it is studied for in laboratory models. Use it to confirm that a certificate of analysis describes the molecule on the label.

Reading a record

Five fields that tie a report to a molecule

Identity data is how you check that a certificate of analysis is about the compound on the label. Each field below answers a different part of that question.

Sequence
The order of amino acids, with any caps, non-standard residues or side-chain additions written out.
Why it matters: A COA names what the lab identified. If the sequence it names isn’t this one, the report is about a different molecule.
Molecular formula
The count of each element in one molecule, for example C62H98N16O22 for BPC-157.
Why it matters: It fixes the mass. Salt forms and counter-ions change it, which is why some reports quote a slightly different figure.
Molar mass
The mass of one mole, in g/mol, calculated from the formula.
Why it matters: A deconvoluted average-mass result should sit close to this number; high-resolution reports give the slightly lower monoisotopic mass, and raw spectra show m/z for charged ions (mass ÷ charge). How HPLC and mass spec work.
CAS number
The Chemical Abstracts Service registry number for the substance.
Why it matters: It pins down one substance when trade names and abbreviations overlap. We quote a CAS number only when PubChem lists it.
PubChem CID
The compound’s record number at PubChem, the US National Library of Medicine’s chemistry database.
Why it matters: It lets you check each identity figure here against the source record yourself, in one click.
