Quality Control

Our Oxytocin, 1-Desaminopenicillamyl-Leu(2)- is manufactured under strict quality systems. Each batch undergoes rigorous analytical testing, including HPLC for purity, MS for identity confirmation, and chiral purity checks, to ensure it meets the high standards required for research applications. Certificates of Analysis (COA) detailing all test results are available upon request. We support compliance with relevant research and development guidelines.

Storage

Preserve in a tightly closed container, protected from light. Store at controlled room temperature (15-25°C) or as specified on the label or COA. This product is hygroscopic (moisture-sensitive); therefore, the container must be kept tightly sealed in a dry environment to prevent degradation. For long-term storage, consider desiccated conditions.
