Quality Control

Our 13-Ethyl-17-Hydroxy-18,19-Dinorpregn-5(10)-En-20-Yn-3-One is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for pharmaceutical research and development. Certificates of Analysis (COA) detailing specific results are available upon request to support your regulatory and quality assurance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent degradation from atmospheric moisture.
