Quality Control

Our (4As)-7α-Ethenyl-1,3,4,4A,4Bα,5,6,7,8,9,10,10Aα-Dodecahydro-1,1,4Aβ,7-Tetramethylphenanthrene-8Aβ,10β(2H)-Diol 10-Acetate is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods, to ensure it meets the stringent requirements for research and synthesis. Certificates of Analysis (COA) with detailed chromatographic data are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a 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.
