Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antimalarial and anticancer agents. Its structure supports the formation of biologically active compounds by serving as a building block in heterocyclic chemistry. Also employed in the preparation of ligands for catalytic processes and in the design of fluorescent probes due to its quinoline backbone, which exhibits favorable photophysical properties. Additionally, it finds use in agrochemical research for developing novel pesticides and herbicides.
