Quality Control

Our Benzene, 1-Ethenyl-4-[2-(Triethoxysilyl)Ethyl]- is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including GC, NMR, and FTIR, to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing identity, assay, and impurity profiles are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed under an inert atmosphere such as nitrogen to prevent degradation. Keep away from heat, sparks, and open flame.
