Used primarily as an intermediate in organic synthesis, especially in the development of pharmaceuticals and agrochemicals. Its structure supports the construction of complex molecules through sulfonamide bond formation, making it valuable in medicinal chemistry for designing bioactive compounds. The presence of bromine allows for further functionalization via cross-coupling reactions such as Suzuki or Heck reactions, enabling the introduction of diverse molecular fragments. It is also employed in the synthesis of fluorinated compounds to enhance metabolic stability and binding affinity in drug candidates.
