description Product Description
Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of fluorinated drug candidates where enhanced metabolic stability and bioavailability are desired. Its halogenated aromatic structure makes it valuable in cross-coupling reactions, such as Suzuki or Buchwald-Hartwig aminations, enabling the construction of complex molecules in medicinal chemistry. Also employed in agrochemical research for designing active ingredients with improved environmental persistence and target specificity. The compound’s difluoro and bromo substituents allow selective functionalization, supporting its role in late-stage diversification during lead optimization.
