Used in the synthesis of chiral compounds, particularly in pharmaceutical research where enantiomeric purity is critical. It serves as a building block for creating active pharmaceutical ingredients (APIs) with specific stereochemistry. Also employed in organic synthesis as a reagent or intermediate for producing sulfoxide-containing molecules, which are valuable in medicinal chemistry and drug development. Additionally, it finds application in asymmetric catalysis, aiding in the production of enantioselective compounds for various industrial and research purposes.
