Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of kinase inhibitors and other biologically active compounds. Its structure allows for selective functionalization in drug molecules, enhancing binding affinity and metabolic stability. Commonly employed in cross-coupling reactions such as Suzuki or Buchwald-Hartwig aminations to build complex heterocyclic systems found in modern therapeutics. Also utilized in agrochemical research for designing novel pesticides with improved efficacy and environmental profiles.
