Quality Control

Our Rel-1α*,2β*-Bis(Trimethylsiloxy)Cyclohexane is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity. We adhere to cGMP principles where applicable, and our quality management system is designed to meet the stringent requirements of the pharmaceutical and fine chemical industries. Comprehensive analytical testing, including GC, HPLC, and NMR, is performed. A Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment.

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 under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from heat, sparks, and open flame.
