Quality Control

Every batch of Trichloro(2-Methyl-2-Butenyl)Silane is produced and tested under stringent quality management protocols to ensure high purity, consistency, and reliability for your critical processes. Our quality assurance includes rigorous analytical testing (GC, NMR) to verify identity and purity against established specifications. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with each shipment, ensuring full traceability and compliance with your internal quality standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at temperatures between 15-25°C. Due to its highly volatile and moisture-sensitive (hygroscopic) nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis and degradation. Keep away from strong acids, bases, and oxidizing agents.
