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 complex heterocyclic compounds that interact with biological targets such as kinases and enzymes involved in disease pathways. Also employed in the preparation of fluorescent probes due to the inherent photophysical properties of the quinoline core, making it useful in bioimaging and diagnostic applications. Additionally, it serves in agrochemical research for designing novel pesticides with improved efficacy and selectivity.
