Quality Control

Our production of 1,1-Bis(Trichlorosilylmethyl)Ethylene adheres to stringent quality protocols to ensure batch-to-batch consistency and high purity for sensitive applications. Each lot undergoes comprehensive analysis including GC, NMR, and FTIR for identity confirmation and purity assessment. A detailed Certificate of Analysis (COA) documenting assay, impurity profile, and physical characteristics is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be handled under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis and degradation. Keep away from heat, sparks, open flames, and incompatible materials such as strong bases and oxidizing agents.
