Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and antiviral agents. Its structure allows for selective modifications, making it valuable in medicinal chemistry for creating compounds with targeted biological activity. 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 research settings for labeling and probing biological pathways due to the presence of the iodine atom, which facilitates detection or radiolabeling.
