Used as a key intermediate in the synthesis of quinoline-based pharmaceuticals, particularly in antimalarial and anticancer agents. Its structure supports the development of bioactive molecules due to the presence of reactive functional groups—hydroxy, methoxy, and ester—that allow for further chemical modifications. Commonly employed in medicinal chemistry for building complex heterocyclic systems with potential antimicrobial and kinase inhibitory activities. Also utilized in research settings to develop fluorescent probes, leveraging the inherent photophysical properties of the quinoline core.
