Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and antiviral agents. Its structure allows for selective functionalization, making it valuable in medicinal chemistry for creating targeted therapies. Commonly employed in cross-coupling reactions such as Suzuki or Buchwald-Hartwig aminations to build complex heterocyclic systems. Also utilized in the preparation of PET radiotracers due to the presence of iodine, enabling imaging applications in neuroscience and oncology.
