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 carboxylic functional groups, enabling diverse chemical modifications. Employed in research for fluorescent probes and sensors, leveraging the inherent fluorescence of the quinoline ring for detecting metal ions or biological molecules. Also explored in the design of kinase inhibitors and other targeted therapies in medicinal chemistry.
