Quality Control

Our 1,2-Bis(Chlorodimethylsilyl)Ethene is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC, NMR, and titration methods, to ensure high purity and consistency. Certificates of Analysis (COA) documenting identity, assay, and impurity profiles are available upon request to support your quality assurance protocols.

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 moisture-sensitive and highly volatile nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis and degradation. Keep away from strong acids and organic solvents.
