Quality Control

Our 2-Cyanoethyltrichlorosilane is manufactured under stringent quality control protocols to ensure batch-to-batch consistency and high purity for demanding industrial applications. Each lot is analyzed using advanced techniques including Gas Chromatography (GC) and FT-IR spectroscopy. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment, ensuring full traceability and compliance with your material specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its highly volatile and hygroscopic nature, the container 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, acids, and oxidizing agents.
