Quality Control

Our Chlorophenylsilane 97 is manufactured under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including GC, HPLC, and NMR analysis, to verify identity, purity, and impurity profiles. We provide a detailed Certificate of Analysis (COA) with every shipment, ensuring full traceability and compliance with your material specifications and internal quality standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be kept under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis and maintain purity. Keep away from heat, sparks, open flames, and incompatible materials such as strong oxidizers, bases, and alcohols.
