Used as a key intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. Its multiple halogen atoms (bromo, bromomethyl, and iodo) allow for selective cross-coupling reactions, enabling the construction of complex aromatic structures. Commonly employed in Suzuki, Stille, and Heck reactions to form carbon-carbon bonds. Also utilized in the development of functional materials and ligands for catalysis due to its versatile reactivity.
