Quality Control

Our 1,1-Dichloro-3,3-Dimethyl-1,3-Disilabutane is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC, NMR, and Karl Fischer titration, to ensure high purity and consistency suitable for sensitive industrial applications. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its hygroscopic and highly volatile nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and decomposition. Keep away from strong acids, bases, and oxidizing agents.
