Quality Control

Our 1-[(3S,5R,8R,9S,10S,13S,14S)-3-Hydroxy-10,13-Dimethyl-2,3,4,5,6,7,8,9, 11,12,14,15-Dodecahydro-1H-Cyclopenta[A]Phenanthren-17-Yl]Ethanone is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC, GC, and NMR, to ensure identity, purity, and stereochemical integrity. Certificates of Analysis (COA) detailing all specifications and test results are provided and can be tailored to meet specific client or regulatory requirements.

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 minimize exposure to atmospheric moisture. For long-term storage, consider using desiccants or an inert atmosphere.
