Description

Silane, dimethoxymethyl(3,3,3-trifluoropropyl)- (CAS No. 358-67-8) is a highly specialized organosilicon compound with the molecular formula C₆H₁₃F₃O₂Si. This fluorinated silane derivative is designed for advanced applications in surface modification, adhesion promotion, and hydrophobic coating formulations. Its unique molecular structure, featuring both methoxy and trifluoropropyl groups, enables exceptional reactivity with inorganic substrates while imparting fluorinated surface properties. The compound is supplied as a high-purity liquid (typically >97% by GC) with strict quality control to ensure batch-to-batch consistency for research and industrial applications. Proper handling under inert atmosphere is recommended due to moisture sensitivity. This product is particularly valuable for developing specialized interfaces in electronic materials, low-surface-energy coatings, and composite materials where fluorinated silane chemistry is required.
