Quality Control

Our Bis(Trimethylsilylmethyl)Dichlorosilane is manufactured under controlled conditions to ensure batch-to-batch consistency and high purity. Each lot undergoes rigorous analytical testing, including GC, NMR, and titration methods, to confirm identity, assay, and impurity profiles. We are committed to supply chain reliability and quality assurance protocols suitable for industrial and research applications. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its hygroscopic and highly volatile nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and decomposition. Keep away from heat, sparks, open flames, and incompatible materials such as strong bases, alcohols, and oxidizing agents.
