Description

Oxytocin (Free Acid) CAS NO 4248-64-0 is the non-amidated, biologically active precursor form of the neuropeptide hormone oxytocin. This high-purity intermediate is critical for pharmaceutical research and development, offering precise control over final product synthesis. It is primarily utilized by biotechnology firms, academic research institutions, and pharmaceutical manufacturers engaged in peptide synthesis, neuroendocrine studies, and the development of therapeutic analogs.

Application

• Pharmaceutical Intermediate: Key starting material for the synthesis of finished oxytocin API and its various therapeutic analogs.
• Biochemical Research: Used in neurobiology and endocrinology studies to investigate oxytocin's role in social behavior, bonding, and uterine contraction mechanisms.
• Reference Standard: Serves as a high-purity calibrant or standard in analytical methods (e.g., HPLC, LC-MS) for quality control of peptide products.
• Peptide Chemistry Development: A model compound for developing and optimizing novel peptide synthesis, purification, and characterization protocols.
• Veterinary Pharmaceutical Development: Investigated for applications in animal husbandry and veterinary medicine related to parturition and lactation.
