Quality Control

Our production of 1,4-Dichloro-2-Trimethoxysilyl-2-Butene adheres to stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including GC, NMR, and Karl Fischer titration, to ensure identity, purity, and consistency. Certificates of Analysis (COA) documenting all critical parameters are 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, and well-ventilated area. Due to its hygroscopic nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture absorption and degradation. Recommended storage temperature is 2-8°C for long-term stability.
