Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of herbicides and fungicides. It serves as a building block in the preparation of complex organic molecules where the presence of both chlorine and iodine allows for selective cross-coupling reactions, such as Suzuki or Heck reactions, enabling the formation of carbon-carbon bonds. Also employed in the production of dyes and pigments due to its aromatic amine functionality, which can undergo diazotization and further transformation into colored compounds. Its reactivity makes it valuable in research and development of new bioactive compounds.
