2-Bromo-3-iodobenzoic acid is primarily utilized as an intermediate in organic synthesis, particularly in the preparation of complex aromatic compounds. Its unique halogen substitution pattern makes it valuable in cross-coupling reactions, such as Suzuki or Sonogashira couplings, to construct biaryl structures or other advanced molecules. This compound is also employed in pharmaceutical research for the development of active pharmaceutical ingredients (APIs) and in material science for designing functionalized polymers or ligands. Additionally, it serves as a precursor in the synthesis of agrochemicals and specialty chemicals, where its halogen atoms enable further functionalization and modification.
