Used as a chiral building block in asymmetric synthesis, particularly in pharmaceutical and agrochemical industries. Its sulfinyl group acts as a directing group in stereoselective transformations and enables the formation of carbon–carbon bonds with high enantiomeric purity. Commonly employed in the preparation of sulfoxide-containing bioactive molecules, where the stereochemistry plays a critical role in biological activity. Also utilized in the synthesis of ligands for asymmetric catalysis due to its stable chiral center and reactivity under mild conditions.
