Quality Control

Our Chloro(Butoxy)Ethylsilane is produced under stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including assay and impurity profile determination, to ensure it meets precise specifications for industrial applications. A Certificate of Analysis (COA) documenting purity, identity, and key physical properties is provided with every shipment to guarantee consistency and traceability.

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 and highly volatile nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture absorption and degradation. Keep away from heat, sparks, and open flame.
