Quality Control

Our Dibenzyldichlorosilane is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced techniques including GC, NMR, and titration to confirm identity and assay. A comprehensive Certificate of Analysis (COA) detailing purity, impurity profile, and physical properties is provided with every shipment, supporting your quality management systems.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials. Due to its hygroscopic and highly volatile nature, containers should be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) and at temperatures between 2°C and 8°C for long-term stability. Handle and open containers with appropriate precautions to minimize exposure to moisture and air.
