Used as a key intermediate in the synthesis of pharmaceuticals, particularly in antimalarial and anticancer agents. Its structure supports the development of bioactive molecules due to the presence of both quinoline core and trifluoromethyl group, which enhance metabolic stability and membrane permeability. Also employed in agrochemicals for crop protection, where it contributes to improved efficacy and environmental stability of active ingredients. Additionally, it serves as a building block in materials science for designing fluorescent probes and optoelectronic materials owing to its electron-withdrawing properties and rigid aromatic framework.
