Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other biologically active compounds. Its structure allows for easy functionalization, making it valuable in medicinal chemistry for creating targeted drug candidates. Commonly employed in cross-coupling reactions, such as Suzuki or Heck reactions, to introduce aromatic or heteroaromatic systems in drug design. Also utilized in the preparation of radiolabeled compounds for imaging studies due to the presence of iodine, enabling applications in PET or SPECT imaging.
