Quality Control

Our (8R,9S,10R,13S,14S,17S)-13-Ethyl-17-Ethynyl-17-Hydroxy-1,2,6,7,8,9,10,11,12,14,15,16-Dodecahydrocyclopenta[A]Phenanthren-3-One is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets exacting research and pharmaceutical-grade standards. Comprehensive Certificates of Analysis (COA) detailing purity, impurities, and physical characteristics are provided to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption. For long-term storage, consider using desiccants or an inert atmosphere.
