Used in organic synthesis, particularly in the preparation of complex aromatic compounds. It serves as a key intermediate in the production of pharmaceuticals, agrochemicals, and dyes. The presence of both bromo and iodo groups allows for selective functionalization, enabling the creation of diverse chemical structures. It is also employed in cross-coupling reactions, such as Suzuki or Sonogashira reactions, to build advanced molecular frameworks. Additionally, it finds use in research and development for studying reaction mechanisms and developing new synthetic methodologies.
