Application

(Ethylsulphonyl)benzene serves as a versatile intermediate in organic synthesis, particularly in the preparation of sulfonamide-based pharmaceuticals. Researchers utilize this compound as a polar solvent additive to enhance reaction yields in Pd-catalyzed cross-coupling reactions. In material science, it functions as a precursor for designing sulfone-containing polymers with high thermal stability. The ethylsulfonyl moiety also finds application in agrochemical synthesis as a metabolically stable functional group.
