Description

Cys-Tyr-Ile-Gln-Asn-Cys-Pro-Arg-Gly-Nh2 is a synthetic nonapeptide amide, also known as Oxytocin, a crucial neurohypophysial hormone. This compound is of paramount importance for its potent biological activity, primarily functioning in uterine contraction and lactation. It is essential for researchers in pharmaceutical development, biochemical research, and manufacturers of reference standards and active pharmaceutical ingredients (APIs).

Application

• Pharmaceutical Active Ingredient (API): Core component in medications for labor induction, postpartum hemorrhage control, and lactation support.
• Biochemical & Neuroscience Research: Vital tool for studying social bonding, stress responses, and neuroendocrine signaling pathways.
• Veterinary Medicine: Used in obstetrical procedures for livestock and companion animals.
• Reference Standard: Serves as a high-purity calibrant in analytical laboratories for quality control and method validation.
• Cell Culture & In Vitro Studies: Applied in research to investigate its effects on cellular receptors and physiological models.
