Quality Control

Every batch of Benzene, [Bis(Fluoromethyl)Methylsilyl]- is manufactured and tested under strict quality management systems. We ensure compliance with relevant industry standards for high-purity organosilicon intermediates. Comprehensive analytical testing, including GC, NMR, and Karl Fischer titration, is performed to verify identity, purity, and moisture content. A Certificate of Analysis (COA) detailing all specifications is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening. Keep away from strong acids and incompatible organic solvents.
