Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and antimalarial agents. Its structure supports the creation of complex heterocyclic compounds with biological activity. Commonly employed in research settings for drug discovery due to its ability to undergo cross-coupling reactions, enabling the introduction of various functional groups. Also utilized in the preparation of fluorescent probes and optoelectronic materials owing to its quinoline backbone, which exhibits favorable photophysical properties.
