Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and antimalarial agents. Its structure supports the construction of complex heterocyclic systems found in bioactive molecules. Commonly employed in cross-coupling reactions such as Suzuki and Buchwald-Hartwig aminations to form carbon-carbon and carbon-nitrogen bonds, enabling the introduction of functional groups for drug optimization. Also utilized in the preparation of fluorescent probes and materials for organic electronics due to its quinoline backbone, which offers favorable photophysical properties.
