Cagrilintide is an acylated analogue of amylin designed for extended activity; research applications include amylin-receptor pharmacology, peptide stability, structural analysis and analytical reference work.
The fatty-acid conjugation shapes chromatographic behaviour markedly: on reversed-phase HPLC, the added lipid chain shifts retention noticeably later compared with unmodified peptides of similar chain length. Given the high molecular weight (4409.0 g/mol, as the acetate), the molecule typically appears in mass spectrometry as a multiply charged ion series that is deconvoluted to determine the overall mass; the disulfide bridge inherited from the amylin backbone, indicated by two sulfur atoms in C194H312N54O59S2, is accounted for in that evaluation.
Purity (≥99% by specification), CAS number 1415456-99-3 and the parameters above make up the specification; the certificate of analysis for each batch is available for the product on request.
