Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of fluorinated and iodinated aromatic compounds. Its structure allows for selective functionalization in drug molecules, enhancing metabolic stability and binding affinity. Commonly employed in the preparation of kinase inhibitors and radiolabeled compounds for medical imaging due to the presence of iodine, which can be substituted with radioactive isotopes. Also utilized in agrochemical research for designing bioactive molecules with improved environmental stability.
