Used as an intermediate in organic synthesis, particularly in pharmaceutical and agrochemical industries. It serves as a building block for introducing the methylsulfonylbenzyl group into target molecules, enhancing structural diversity in drug design. Commonly employed in cross-coupling reactions such as Suzuki or Heck reactions due to the reactive bromine atom. Also utilized in the preparation of sulfone-containing compounds, which can exhibit biological activity or act as precursors in materials science. Its stability and reactivity make it suitable for controlled functionalization in multi-step syntheses.
