Used primarily as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of fluorinated drug candidates where the presence of fluorine atoms enhances metabolic stability and bioavailability. The iodo group allows for further functionalization via cross-coupling reactions such as Suzuki or Heck couplings, enabling the construction of complex aromatic systems. Its structure is valuable in medicinal chemistry for optimizing lead compounds in treatments targeting inflammation, CNS disorders, and oncology. Also employed in the preparation of radiolabeled compounds for imaging studies, leveraging the iodine atom for incorporation of radioactive isotopes.
