Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and antimalarial agents. Its halogenated quinoline structure allows for selective cross-coupling reactions, enabling the construction of complex bioactive molecules. Commonly employed in research settings for drug discovery due to its reactivity and ability to serve as a building block in heterocyclic chemistry. Also utilized in the preparation of fluorescent probes and materials for organic electronics owing to the quinoline core’s photophysical properties.
