Used in pharmaceutical research as a key intermediate for synthesizing bioactive molecules, particularly in the development of antimalarial and anticancer agents. Its structure supports the formation of complex heterocyclic compounds that interact with biological targets such as enzymes and receptors. Also employed in the preparation of fluorescent probes due to the quinoline moiety’s inherent photophysical properties, enabling applications in cellular imaging and diagnostic assays. The amine group allows for easy functionalization, making it valuable in combinatorial chemistry and drug discovery.
