Quality Control

Our Silane, (3-Chloropropyl)dimethyl(1-methylethoxy)- is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC and NMR, to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing purity, identity, and key specifications are provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive); containers must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis and maintain product integrity.
