Quality Control

Our 2,5-Dichloro-2,5-Dimethyl-2,5-Disila-3-Hexyne is produced and handled under strict quality protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes rigorous analytical testing, including GC, NMR, and FTIR analysis, to confirm identity and purity. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment to support your quality assurance requirements.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and hygroscopic nature, this material should be stored in a cool (15-25°C), dry place under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and decomposition. Ensure adequate ventilation in storage areas and keep away from strong acids and oxidizing agents.
