Quality Control

Our production of trans-Bis(trimethoxysilyl)-1,4-dioxane adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including assay by GC or HPLC, identity confirmation via FT-IR and NMR, and control of key impurities and moisture content. A Certificate of Analysis (COA) detailing all test results is provided with each shipment to ensure traceability and compliance with your material specifications and internal quality standards.

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). This compound is hygroscopic (moisture-sensitive). Containers 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.
