Quality Control

Our 10-Undecenyltrimethoxysilane is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including chromatographic purity analysis and functional group verification, to ensure consistency and performance. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed and under a dry inert atmosphere (e.g., nitrogen) for long-term storage to prevent hydrolysis and maintain purity.
