Quality Control

Our Silane, Ethenyldimethylpropo?Xy- CAS NO 959289-55-5 is produced and handled under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistency, purity, and compliance with agreed specifications. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with every shipment and is available upon request.

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, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation by atmospheric moisture.
