Quality Control

Our 2-Chloroethylmethyldichlorosilane is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including GC and NMR analysis, to ensure high purity and consistency. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles 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, well-ventilated area away from heat and incompatible materials such as strong bases, oxidizers, and water. Due to its moisture-sensitive (hygroscopic) nature, containers should be kept tightly sealed under an inert atmosphere (e.g., nitrogen) when not in use to prevent hydrolysis. Recommended storage temperature: 2-8°C for extended shelf life.
