Used as a key intermediate in organic synthesis, particularly in cross-coupling reactions such as Suzuki, Stille, and Ullmann reactions. Its multiple halogen substituents allow for selective and sequential bond formation, making it valuable in the construction of complex aromatic systems. Commonly employed in the development of pharmaceuticals, agrochemicals, and functional materials like organic semiconductors and liquid crystals. The presence of bromine and iodine offers flexibility in reaction conditions due to differing reactivity, enabling controlled stepwise derivatization of the benzene ring.
