Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of sulfoximine-based compounds with biological activity. It serves as a polar aprotic solvent in organic reactions, facilitating transformations where high solvating power and thermal stability are required. Its structural similarity to DMSO makes it useful in modifying reaction pathways or improving selectivity in certain catalytic processes. Also investigated for use in crop protection agents due to the metabolic stability imparted by the sulfoximine moiety.
