Quality Control

Our production of 1,2-Bis(Methyldiethoxysilyl)Ethylene adheres to stringent quality management protocols. Each batch undergoes rigorous analytical testing, including GC, NMR, and FTIR analysis, to ensure chemical identity, purity, and consistency. Certificates of Analysis (COA) detailing assay and impurity profiles are provided and can be tailored to meet specific customer requirements and industry standards.

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). Due to its 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 degradation. Keep away from heat, sparks, and open flame.
