Description

Oxytocin, 1-(2-Hydroxy-3-Mercaptopropionic Acid)- CAS NO 35924-96-0 is a synthetic cyclic nonapeptide analog of the endogenous hormone oxytocin, modified at the 1-position with a 2-hydroxy-3-mercaptopropionic acid residue. This modification can enhance stability and alter receptor binding affinity, making it a valuable tool for advanced pharmaceutical research and development. It is primarily utilized by biopharmaceutical companies and research institutions focused on neuroendocrinology, peptide therapeutics, and reproductive medicine.

Application

• Pharmaceutical Reference Standard: Serves as a certified reference material (CRM) for quality control and assay validation of oxytocin-based drugs.
• Biochemical Research: Used in receptor binding studies, signal transduction pathway analysis, and structure-activity relationship (SAR) investigations for oxytocin and vasopressin receptors.
• Peptide Drug Development: Acts as a key intermediate or active pharmaceutical ingredient (API) in the development of novel therapeutic agents targeting social behavior, lactation, and uterine contraction.
• Diagnostic Kit Manufacturing: Employed in the production of immunoassay kits and other diagnostic reagents for hormonal analysis.
• Neuroscience Studies: Applied in preclinical research to study the role of oxytocin in social bonding, stress response, and anxiety.

Quality Control

Our Oxytocin, 1-(2-Hydroxy-3-Mercaptopropionic Acid) is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, peptide mapping, and residual solvent analysis, to ensure it meets stringent specifications for research and development use. Certificates of Analysis (COA) with detailed chromatographic data are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below. This product is hygroscopic (moisture-sensitive). Allow the vial to reach room temperature in a desiccator before opening to prevent condensation and hydrolysis. For long-term storage, keep under an inert atmosphere.
