Quality Control

Our 1,1,2,2-Tetraethoxy-1,2-Dimethyldisilane is manufactured under strict quality protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including GC, NMR, and FTIR analysis, to verify identity and purity. A detailed Certificate of Analysis (COA) documenting all specifications is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong bases and organic solvents. Recommended storage temperature is 2-8°C to maintain optimal stability. The container should be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and degradation.
