Quality Control

Our 1,3-Bis(Dimethylsilyl)Benzene is manufactured under strict quality management systems. Each batch undergoes comprehensive analysis using techniques including GC, NMR, and Karl Fischer titration to ensure identity, purity, and consistency. A Certificate of Analysis (COA) detailing all test results is provided with every shipment, ensuring full traceability and compliance with your material specifications.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile nature, store in a cool, well-ventilated place, ideally at 2-8°C or as specified on the label. Keep away from heat, sparks, and open flames. Containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and degradation.
