Quality Control

Our 2,2,9,9-Tetramethyl-5,6-Bis[[(Trimethylsilyl)Oxy]Methyl]-3,8-Dioxa-2,9-Disiladecane is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure high chemical purity and identity confirmation. Certificates of Analysis (COA) documenting purity, assay, and impurity profiles are available for every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture absorption and degradation.
