Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of kinase inhibitors and other biologically active compounds. Its halogen substituents allow for selective cross-coupling reactions, such as Suzuki or Heck reactions, enabling the construction of complex aromatic systems. Commonly employed in medicinal chemistry for structure-activity relationship studies due to the ease of functionalization at the bromo and iodo sites. Also utilized in the preparation of ligands for catalysis and in materials science for designing organic semiconductors.
