Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. Its structure allows for selective functionalization, making it valuable in constructing biologically active molecules. Commonly employed in cross-coupling reactions such as Suzuki and Negishi couplings to build complex heterocyclic systems. Also utilized in agrochemical research for designing novel pesticides with improved efficacy and selectivity. Its bromo and sulfonyl groups act as handles for further chemical modifications, enabling diverse derivatization in medicinal chemistry campaigns.
