Oxytocin
Oxytocin (CAS 50-56-6) is a naturally occurring cyclic nonapeptide hormone; the CAS identity aligns with its name, formula C43H66N12O12S2, and molecular weight of 1007.19 g/mol. Its sequence is Cys-Tyr-Ile-Gln-Asn-Cys-Pro-Leu-Gly-NH2, with a disulfide bridge between cysteine residues. Synthesized in hypothalamic neurons and released from the posterior pituitary, oxytocin binds specific oxytocin receptors, including receptors on uterine smooth muscle and mammary myoepithelial cells.
Pharmaceutical oxytocin formulations have established obstetric uses, principally induction or augmentation of labor when indicated and management of the third stage of labor to reduce postpartum bleeding; approved indications and labeling vary by jurisdiction. The molecule is also used in receptor, endocrine, and neurobehavioral research, but experimental findings are not proof of benefit for social behavior or other conditions. A supplier’s “pharmaceutical grade” descriptor alone does not establish sterility, injectable suitability, clinical authorization, or fitness as a reference standard; those depend on product-specific specifications and applicable regulatory controls.
– Regulated obstetric therapy: Pharmaceutical oxytocin formulations are used to induce labor or augment inadequate uterine contractions when clinically indicated. Use depends on the locally authorized product labeling and clinical assessment; this listing alone does not establish that the supplied material is suitable for administration to patients.
– Third-stage labor and postpartum bleeding: In obstetric care, oxytocin is used in management of the third stage of labor and prevention or treatment of postpartum hemorrhage, as uterine contraction supports hemostasis. Indications and approved product status vary by jurisdiction and require qualified clinical care.
– Receptor and endocrine research: Suitably characterized oxytocin can support laboratory studies of oxytocin-receptor binding and signaling, and responses in uterine or mammary-cell systems. These are research applications, not evidence that a supplier’s material is a validated assay standard or approved intervention; verify its specification for the intended study.
– Neurobehavioral research and pharmaceutical quality work: Oxytocin is investigated in preclinical and clinical research on central signaling and behavior; analytical characterization may also support identity, content, or impurity assessment in regulated peptide manufacture.
