Used as a key intermediate in the synthesis of pharmaceuticals, particularly in antimalarial and anticancer agents. Its trifluoromethyl group enhances metabolic stability and bioavailability in drug candidates. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to its ability to modulate lipophilicity and electron-withdrawing properties. Also utilized in the development of agrochemicals and fluorescent probes for biological imaging, leveraging its quinoline core for binding interactions and optical characteristics.
