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 DNA. Also employed in research for developing fluorescent probes due to its ability to form stable complexes with metals and exhibit luminescent properties. Commonly utilized in medicinal chemistry for structure-activity relationship (SAR) studies involving quinoline-based drug candidates.
