Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antimalarial and anticancer agents. Its structure allows for selective functionalization, making it valuable in medicinal chemistry for building complex heterocyclic compounds. Also employed in coordination chemistry as a ligand for metal ions, aiding in the creation of catalysts for organic transformations. Additionally, it finds use in research related to fluorescent probes due to the quinoline core’s photophysical properties.
