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 the electron-withdrawing trifluoromethyl group and the reactive hydroxyl functionality. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies. Also utilized in the preparation of fluorescent probes and sensors owing to its quinoline backbone, which exhibits favorable photophysical properties. Plays a role in agrochemical research for designing new pesticidal and fungicidal compounds.
