Pharmaceutical-grade Oxytocin Acetate (CAS 50-56-6), ≥98.0% HPLC, supplied wholesale by Zyntex to licensed producers. Nonapeptide hormone API for human and veterinary injectables, shipped under cold-chain conditions. CoA and SDS.
Oxytocin (C43H66N12O12S2) is a cyclic nonapeptide with a disulfide bridge. It is supplied as the acetate salt, a white lyophilized powder that dissolves easily in water. It differs from Vasopressin in only two amino acids.
Pharmaceutical companies use it in injectable solutions in obstetric care, and veterinary producers use it in injections for cattle, pigs and other animals. Because the peptide degrades with heat, most oxytocin injections require refrigerated storage; the longer-acting, more stable analogue Carbetocin addresses this limitation.
Key quality parameters are HPLC purity, peptide content, related peptides, acetate and water content, and bacterial endotoxins. Related peptide APIs in our range include Desmopressin and Terlipressin.
