Quality Control

Our production of 1,1,4,4-Tetramethyl-1,4-Diethoxydisilethylene adheres to stringent internal quality protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced techniques including GC, NMR, and Karl Fischer titration. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment, supporting your quality assurance and regulatory compliance 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). 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.
