Used in pharmaceutical synthesis as a key intermediate for bioactive compounds, particularly in antimalarial and antiviral drug development. Its trifluoromethyl group enhances metabolic stability and lipophilicity, improving drug absorption and efficacy. Also employed in agrochemicals to create pesticides with increased resistance to degradation. Serves as a building block in materials science for designing organic semiconductors and fluorescent probes due to its electron-withdrawing properties and aromatic structure.
