Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the production of active ingredients requiring high enantiomeric purity. Its strained epoxide ring allows ring-opening reactions with nucleophiles, enabling the introduction of fluorinated side chains into complex molecules. Commonly applied in the development of agrochemicals and biologically active compounds where the trifluoromethyl group enhances metabolic stability and lipophilicity. Also employed in research for asymmetric synthesis due to its ability to maintain stereochemistry during transformations.
