Quality Control

Our Dichloro(Methyl)(p-Tolyl)Silane is manufactured under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including assay and impurity profiling by GC and NMR, to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing all specifications are provided and available upon request to support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its highly volatile and hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis and maintain product integrity. Keep away from heat, sparks, and open flame.
