CAS number
A unique numeric identifier assigned by Chemical Abstracts Service to every chemical substance.
A CAS Registry Number is a unique numeric identifier assigned by the American Chemical Society's Chemical Abstracts Service (CAS) to every chemical substance described in scientific literature. The format is up to 10 digits in three hyphen-separated parts (e.g. 137525-51-0 for BPC-157). Researchers use CAS numbers to look up the same substance across databases regardless of naming variations or aliases. A research peptide COA typically lists the CAS number when one has been assigned.
- GlossaryCOA (Certificate of Analysis)
Document showing the analytical results — typically purity, mass, and identity — for a specific batch of research peptide.
- GlossaryHPLC
High-performance liquid chromatography — the standard purity assay for research peptides.
- GlossaryMass spectrometry
Identifies a compound by measuring its mass-to-charge ratio.
