Quality Control

Our 1,1,2-Trichloro-1,2,2-Trimethyldisilane is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analysis, including GC, NMR, and Karl Fischer titration, to verify identity, potency, and impurity profiles. Certificates of Analysis (COA) documenting all test results are provided and can be tailored to meet specific customer or regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat sources and incompatible materials such as strong bases, oxidizing agents, and moisture. Due to its highly volatile and reactive nature, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep container tightly sealed when not in use.
