Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of antimalarial and anticancer agents. Its structure allows for further functionalization, making it valuable in medicinal chemistry for building complex heterocyclic systems. Commonly employed in research settings to develop kinase inhibitors and other biologically active molecules. Also utilized in the preparation of fluorescent probes due to its quinoline backbone, which can intercalate into DNA, aiding in biochemical assays and cellular imaging.
