Quality Control

Our production of 1,4-Dichloro-2-(Trichlorosilyl)-2-Butene adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including GC, NMR, and titration, to ensure high purity and consistent performance. A detailed Certificate of Analysis (COA) is provided with each shipment, confirming compliance with agreed specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials. Due to its hygroscopic and highly volatile nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) and away from moisture. Recommended storage temperature is 2-8°C for extended stability.
