What is Oxytocin??
Oxytocin Acetate (CAS 6233-83-6) is the acetate salt of the endogenous nonapeptide neurohormone oxytocin (Cys-Tyr-Ile-Gln-Asn-Cys-Pro-Leu-Gly-NH₂, disulfide bridge Cys¹–Cys⁶). Molecular formula C₄₃H₆₆N₁₂O₁₂S₂ (free acid), MW 1007.19 g/mol. Produced in hypothalamic paraventricular and supraoptic nuclei and released from the posterior pituitary, oxytocin acts at the oxytocin receptor (OTR, Gq-linked) — influencing uterine contractility, lactation, social bonding, trust, anxiety, and pain modulation. It also cross-reacts with the vasopressin V1/V2 receptors at higher concentrations.
