Quality Control

Our Tetrakis(Dimethylsilyl)Silane is produced under stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including assay by GC or NMR and impurity profiling, to ensure high purity and consistency for research and industrial applications. A Certificate of Analysis (COA) detailing specific results is provided with every shipment to guarantee reliable performance in your processes.

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 and highly volatile nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture absorption and decomposition.
