Used as a key intermediate in organic synthesis, particularly in the development of pharmaceuticals and agrochemicals. Its strained ring structure and reactive bromine functionality make it valuable for ring-opening reactions and carbon-chain elongation. It is often employed in the preparation of sulfone-containing compounds, which can act as Michael acceptors or participate in nucleophilic substitution reactions. Due to the electron-withdrawing nature of the sulfone group, it enhances the reactivity of the adjacent bromine, facilitating cross-coupling reactions such as Suzuki or Heck reactions when transition metal catalysts are used. Also finds use in the synthesis of cyclic and acyclic sulfur-based compounds with potential biological activity.
