Used primarily as an intermediate in organic synthesis, especially in cross-coupling reactions such as Suzuki, Stille, and Negishi couplings. Its dual halogen functionality allows for selective and sequential bond formation, making it valuable in the construction of complex aromatic and polycyclic structures. Commonly employed in the development of pharmaceuticals, agrochemicals, and organic electronic materials where precise molecular architecture is required. The presence of both bromo and iodo groups offers flexibility in reaction planning due to their differing reactivities under various catalytic conditions.
