Quality Control

Our production of 1,1,1-Trimethyl-4,4-Dichloro-4-Vinyldisilethylene adheres to a stringent quality management system. Every batch undergoes rigorous analytical testing, including GC, NMR, and FTIR, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications 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, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from heat, sparks, and open flame.
