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 functionalization, making it valuable in medicinal chemistry for creating compounds with high biological activity. Commonly employed in cross-coupling reactions, such as Suzuki or Buchwald-Hartwig, to build complex pyridine-based molecules. Also utilized in the preparation of radiolabeled compounds for imaging studies due to the presence of iodine, enabling tracking in biological systems.
