Quality Control

Our Diisopropenoxydimethylsilane is produced under stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including assay by GC or NMR and impurity profiling, to ensure it meets the high-purity standards required for research and industrial applications. A Certificate of Analysis (COA) detailing specific results is provided with every shipment.

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 material is moisture-sensitive (hygroscopic) and should be kept under an inert atmosphere (e.g., nitrogen or argon) to prevent degradation. Keep away from strong acids, bases, and oxidizing agents.
