Cagrilintide is a synthetic long-acting analog of amylin, a 37-amino acid hormone naturally co-secreted with insulin from pancreatic beta cells. It features specific amino acid substitutions and a fatty acid acylation that slows clearance from solution. The compound has the molecular formula C₁₉₄H₃₁₂N₅₄O₅₉S₂, a molecular weight of approximately 4,409 g/mol, and CAS number 1415456-99-3. It is supplied as a white lyophilized powder, soluble in water. The fatty acid sidechain enables albumin binding and extends persistence compared to native amylin. This product is strictly for research purposes only.
