Used in pharmaceutical research as a key scaffold for developing bioactive compounds, particularly in the design of antiviral and anticancer agents. Its electron-withdrawing trifluoromethyl group enhances metabolic stability and membrane permeability, making it valuable in optimizing drug candidates. Also employed in agrochemicals to improve the efficacy of pesticides and herbicides due to its resistance to degradation. Additionally, serves as a ligand in coordination chemistry for catalytic applications.
