Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of antimalarial and anticancer agents. Its structure supports the formation of complex heterocyclic compounds that exhibit biological activity. Commonly employed in medicinal chemistry for constructing kinase inhibitors and antimicrobial agents. Also utilized in research settings to develop fluorescent probes due to the inherent photophysical properties of the quinoline backbone. Plays a role in the preparation of dyes and functional materials where bromine serves as a site for further functionalization via cross-coupling reactions.
