A unique numerical identifier assigned by the Chemical Abstracts Service to every chemical substance. Each peptide has a specific CAS number (e.g., BPC-157: 137525-51-0) that allows unambiguous identification regardless of naming conventions.
"CAS Number" is filed under Quality in the PeptideAtlas glossary, alongside 12 other terms in that group.
A document from a laboratory (ideally third-party) that certifies the identity, purity, potency, and quality of a substance. Essential for verifying research peptide quality.
An analytical technique used to separate, identify, and quantify components in a mixture. Used in COAs to determine peptide purity percentage.
An analytical technique that measures the mass-to-charge ratio of molecules. Used in COAs to confirm peptide identity and molecular weight.
