Used primarily as an intermediate in the synthesis of pharmaceuticals, particularly in the development of antimalarial and anticancer agents. Its halogenated structure allows for selective cross-coupling reactions, enabling the introduction of various functional groups during drug design. It is also employed in the preparation of quinoline-based fluorescent probes for biochemical imaging. Due to the presence of both bromo and iodo substituents, it offers sequential reactivity, making it valuable in multi-step organic synthesis for creating complex heterocyclic systems.
