Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. It participates in cross-coupling reactions, such as Suzuki and Heck reactions, enabling the formation of carbon-carbon bonds. Its sulfone group stabilizes adjacent carbanions, making it useful in nucleophilic addition and elimination reactions. Also employed in the synthesis of functionalized benzyl compounds and heterocyclic systems. Shows utility in medicinal chemistry for constructing biologically active molecules due to its reactivity and structural features.
