Quality Control

Our 1,1,1,2-Tetrachloro-2,2-dimethyldisilane is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity suitable for industrial and research applications. Each lot is analyzed using advanced techniques including GC, NMR, and Karl Fischer titration. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to guarantee compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic and highly volatile nature, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) at temperatures between 2°C and 8°C for long-term stability. Keep away from heat, sparks, open flames, and incompatible materials such as strong bases and oxidizing agents.
