Quality Control

Our production of Dichlorobis(trichloromethyl)silane adheres to a stringent quality management system. Every batch undergoes comprehensive analytical testing, including assay by GC or titration and impurity profiling, to ensure consistency and high purity suitable for industrial and research applications. A Certificate of Analysis (COA) detailing all specifications is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat and incompatible materials. Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis. Recommended storage temperature is 2-8°C for extended stability.
