Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the preparation of iodinated and chlorinated aromatic compounds. It serves in the development of active ingredients for crop protection products and in the production of certain antiseptics and disinfectants. Also utilized in research settings for derivatization reactions and as a building block in organic synthesis, especially in cross-coupling reactions such as Suzuki and Heck reactions where the iodine moiety acts as a reactive site. Its halogen functionality allows for selective modifications in multi-step synthesis pathways.
