Used primarily as an intermediate in the synthesis of pharmaceuticals and agrochemicals. It serves as a building block in the preparation of complex organic molecules, especially in the development of active pharmaceutical ingredients (APIs) where halogenated anilines are required. The presence of both bromo and iodo substituents allows for selective cross-coupling reactions, such as Suzuki or Heck reactions, enabling the construction of carbon-carbon bonds in fine chemical synthesis. Also employed in the research and development of functional dyes and fluorescent probes due to its reactivity and structural properties. Its dual halogen functionality makes it valuable in stepwise synthesis where sequential coupling reactions are needed.
