Quality Control

Our Di-tert-Butyl-Diethoxysilane is manufactured under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including chromatography and spectroscopy, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are provided with every shipment to guarantee compliance with your technical requirements.

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 moisture.
