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 analogs with improved potency and selectivity. 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 agrochemical research for designing new active ingredients with targeted modes of action.
