Used as a key 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 bromo and hydroxyl functional groups, which allow for further chemical modifications. Commonly employed in cross-coupling reactions such as Suzuki or Buchwald-Hartwig aminations to construct complex heterocyclic systems found in bioactive molecules. Also utilized in agrochemical research for designing novel pesticides with improved selectivity and efficacy.
