Quality Control

Our 10,13-Dimethyl-17-Sulfanyl-1,2,6,7,8,9,11,12,14,15,16,17-Dodecahydrocyclopenta[a]phenanthren-3-One is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC, GC, and NMR, to ensure identity, purity, and consistency. Certificates of Analysis (COA) are provided with each shipment, detailing all relevant specifications. We support cGMP standards for pharmaceutical applications and can tailor purity grades to meet specific project 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 sensitivity to oxidation, prolonged storage under an inert atmosphere (e.g., nitrogen or argon) is recommended for optimal long-term stability. Keep away from strong oxidizing agents.
