Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of antimalarial and antimicrobial agents. Its structure supports the creation of complex heterocyclic systems important in medicinal chemistry. Also employed in research settings for the preparation of fluorescent probes and dyes due to its quinoline backbone, which exhibits favorable photophysical properties. Additionally, it serves as a building block in the design of kinase inhibitors and other biologically active molecules in drug discovery programs.
