Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors for cancer treatment. It serves as a building block in the preparation of active pharmaceutical ingredients (APIs) due to its reactive halogen sites, which allow for selective cross-coupling reactions such as Suzuki or Buchwald-Hartwig aminations. Its structure supports the construction of complex heterocyclic systems found in bioactive molecules. Also employed in agrochemical research for designing novel pesticides with improved efficacy and selectivity.
