Quality Control

Our 1-Ethyl-1,1,2,2,2-Pentamethyldisilane is produced and handled under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including GC, NMR, and Karl Fischer titration, to ensure high purity and consistent performance. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming identity, purity, and relevant specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its highly volatile nature, keep the container tightly sealed and under an inert atmosphere (e.g., nitrogen or argon) when not in use to prevent degradation and maintain purity. Recommended storage temperature is 2-8°C for long-term stability.
