Used as an 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 building complex heterocyclic compounds. Commonly employed in cross-coupling reactions such as Suzuki or Buchwald-Hartwig to introduce aryl or amino groups. Also utilized in agrochemical research for designing bioactive molecules. Its halogen atoms provide sites for further chemical modification, enabling rapid diversification in drug discovery programs.
