Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other bioactive molecules. Its structure allows for selective functionalization, making it valuable in medicinal chemistry for creating compounds with high target specificity. Commonly employed in cross-coupling reactions such as Suzuki or Buchwald-Hartwig aminations to build complex heterocyclic systems found in drug candidates. Also utilized in the preparation of radiolabeled compounds for imaging studies due to the presence of iodine, which can be replaced with radioactive isotopes.
