Semaglutide is a GLP-1 analogue with a 31-amino-acid peptide backbone and a C18 fatty di-acid side chain attached through a linker; defined structural modifications at specific positions support its use as a reference material in peptide-engineering and receptor-focused laboratory studies.
The C18 side chain is the dominant factor in chromatographic behaviour: it shifts RP-HPLC retention markedly toward higher hydrophobicity, yet because the acylation is uniform and well defined, it still produces a sharp, reproducible peak. MS identity is confirmed via a multiply charged ion series, deconvoluted against the theoretical molecular weight of 4113.58 g/mol.
Purity (≥99% by specification), CAS number 910463-68-2 and formula C187H291N45O59 make up the specification; the certificate of analysis for each batch is available for the product on request.
