Description

Oxytocin CAS NO 50-56-6 is a cyclic nonapeptide hormone and neuropeptide that plays a critical role in social bonding, reproduction, and childbirth. Its primary commercial and research value lies in its potent uterotonic and milk-ejection properties, making it a cornerstone in obstetric and veterinary medicine. This high-purity peptide is essential for pharmaceutical manufacturers, research institutions, and biotechnology companies developing therapeutics, diagnostic tools, and conducting advanced neuroendocrine studies.

Application

• Pharmaceutical Active Ingredient: Primary use as the active pharmaceutical ingredient (API) in injectable formulations to induce labor, control postpartum hemorrhage, and stimulate uterine contractions.
• Veterinary Medicine: Used to assist with parturition and milk letdown in livestock, including cows, sheep, and pigs.
• Biomedical Research: A vital tool in neuroscience and psychology research for studying social behavior, pair bonding, stress response, and maternal instincts.
• Diagnostic Reagent: Employed in the development of immunoassays and diagnostic kits for hormonal analysis.
• Reference Standard: Serves as a high-purity chemical reference standard (CRS) for quality control and analytical method development in pharmaceutical laboratories.
• Cell Culture & Biochemistry: Used in in vitro studies to investigate cellular signaling pathways mediated by the oxytocin receptor.
