Quality Control

Every batch of 1-(3-Glycidoxypropyl)-1,1,3,3,3-Pentaethoxy-1,3-Disilapropane is manufactured and tested under a strict Quality Management System. Our products undergo rigorous quality testing, including advanced chromatographic and spectroscopic methods, to ensure compliance with industry standards and precise customer specifications. Certificates of Analysis (COA) detailing purity, identity, and key physical properties are available upon request to support your quality assurance and regulatory documentation needs.

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/59-77°F). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis and maintain product integrity. Keep away from heat, sparks, and open flame.
