Quality Control

Our production of Trichloro(3-Chloro-2-Methylpropyl)Silane adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including assay by GC, to ensure high purity and consistency. Certificates of Analysis (COA) documenting all critical parameters are provided and available upon request to support your quality assurance processes.

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, oxidizers, and moisture. 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 hydrolysis and degradation. Recommended storage temperature is 2-8°C for extended stability.
