Carbetocin
China [CN] Carbetocin (CAS: 37025-55-1), also known as Carbetocin Trifluoroacetate Salt, is a synthetic polypeptide oxytocin analogue with the molecular formula C45H69N11O12S and a molecular weight of 988.16. This product appears as a white to off-white hygroscopic powder, with a melting point ranging from 140–160°C. It is slightly soluble in DMSO and methanol, and soluble in water up to 29.65 mg/mL, with a specific optical rotation of D -69.0° (c = 0.25 in 1M acetic acid). For optimal stability, store the material at -15°C away from moisture. Widely applied in pharmaceutical raw material custom synthesis, generic peptide formulation consistency evaluation, and research use, it features the peptide sequence BUTYRYL-TYR(ME)-ILE-GLN-ASN-CYS-PRO-LEU-GLY-NH2 with a sulfide bond linkage, serving as a key active pharmaceutical peptide intermediate for obstetric drug development.
