Used in the synthesis of pharmaceutical intermediates, particularly in the development of antimalarial and anticancer agents. Its structure serves as a key building block in heterocyclic chemistry, enabling the formation of complex quinoline-based compounds. It is also employed in research for creating novel organic materials and in the design of catalysts for cross-coupling reactions. Due to the presence of bromine, it readily participates in palladium-catalyzed reactions like Suzuki and Heck couplings, making it valuable in medicinal chemistry and drug discovery.
