Description

Oxytocin, Gly(7)- CAS NO 19748-53-9 is a synthetic analogue of the neuropeptide hormone oxytocin, specifically modified at the seventh position with a glycine residue. This structural modification is of significant interest for advanced biochemical and pharmacological research, offering a tool to study receptor specificity and peptide stability. It is primarily utilized by research institutions and pharmaceutical developers focused on neuroendocrinology, peptide therapeutics, and molecular biology.

Application

• Biochemical Research: Used as a reference standard and tool for studying oxytocin receptor binding, signaling pathways, and structure-activity relationships (SAR).
• Pharmaceutical Development: Serves as a key intermediate or active pharmaceutical ingredient (API) in the research and development of novel peptide-based therapeutics.
• Neuroendocrinology Studies: Applied in experimental models to investigate the role of oxytocin analogues in social behavior, stress response, and reproductive physiology.
• Analytical Standard: Employed as a high-purity calibrant in chromatographic (HPLC, LC-MS) and spectroscopic analyses for method development and validation.
• Peptide Chemistry: Acts as a building block or model compound in solid-phase peptide synthesis (SPPS) and other synthetic methodologies.
