Used as a versatile reagent in organic synthesis, particularly in the introduction of trifluoromethyl-containing silane groups into molecules. Its chloromethyl group allows for further functionalization through nucleophilic substitution, making it valuable in the development of fluorinated building blocks for pharmaceuticals and agrochemicals. The presence of the trifluoromethyl group enhances metabolic stability and lipophilicity, which is advantageous in drug design. It is also employed in the preparation of silicon-based functional materials and surface modifiers, where the combination of reactivity and fluorinated character improves performance in coatings and polymers.
