Used in organic synthesis as an intermediate for pharmaceuticals and bioactive compounds. Serves as a building block in the preparation of kinase inhibitors and other nitrogen-containing heterocyclic drugs. Its iodo functional group allows for cross-coupling reactions, such as Suzuki or Heck reactions, enabling the construction of complex aromatic systems. Also employed in the development of ligands for metal-catalyzed reactions and in medicinal chemistry for labeling or radioimaging due to the presence of iodine.
