Used primarily as an intermediate in the synthesis of pharmaceuticals and agrochemicals. Its structure allows for selective functionalization in cross-coupling reactions, making it valuable in the development of active ingredients in crop protection agents. Also employed in the preparation of kinase inhibitors and other biologically active compounds in medicinal chemistry research. The presence of iodine facilitates palladium-catalyzed reactions such as Suzuki or Heck couplings, enabling the construction of complex aromatic systems.
