Used primarily as a key intermediate in the synthesis of pharmaceuticals and agrochemicals, this compound serves as a sulfonylating agent in organic reactions. It enables the introduction of sulfonyl groups into heterocyclic or aromatic systems, enhancing molecular stability and reactivity in drug design. Its bromine substituents allow for further functionalization via cross-coupling reactions such as Suzuki or Heck reactions, making it valuable in building complex molecules. It is also employed in the development of bioactive compounds, including kinase inhibitors and antimicrobial agents, due to its ability to modulate electronic and steric properties in target molecules.
