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 selective functionalization, making it valuable in medicinal chemistry for creating targeted drug candidates. Commonly employed in cross-coupling reactions, such as Suzuki or Buchwald-Hartwig, to introduce the pyridine core into larger molecules. Also utilized in agrochemical research for designing novel pesticides and herbicides due to its electron-withdrawing properties and stability. Preferred in late-stage diversification strategies because the iodine handle enables efficient derivatization.
