Used as an intermediate in organic synthesis, particularly in cross-coupling reactions such as Suzuki, Stille, and Negishi couplings. Its dual halogen functionality allows selective activation, where the iodine participates first in metal-catalyzed reactions due to its higher reactivity, leaving the bromine available for subsequent transformations. This makes it valuable in the construction of complex aromatic systems found in pharmaceuticals, agrochemicals, and functional materials. Commonly employed in the development of drug candidates and bioactive molecules where substituted benzene derivatives are required.
