Quality Control

Our tert-Butyl-[10,13-Dimethyl-17-(1,4,5-Trimethyl-Hex-2-Enyl)-2,3,4,9,10,11,12,13,14,15,16,17-Dodecahydro-1H-Cyclopenta[A]Phenanthren-3-Yloxy]-Dimethyl-Silane is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are provided and can be tailored 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 hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
