Used as a key intermediate in the synthesis of quinoline-based pharmaceuticals, particularly in antimalarial drugs. Its structure supports the development of bioactive molecules due to the presence of both amino and ester functional groups, which allow for further chemical modifications. Commonly employed in medicinal chemistry for building heterocyclic compounds with potential antimicrobial and anticancer activities. Also utilized in research settings to develop fluorescent probes, thanks to the inherent fluorescence of the quinoline scaffold.
