(S)-SDP is widely used as a chiral building block in asymmetric synthesis, particularly in the pharmaceutical industry. It serves as a key intermediate in the preparation of optically active compounds, including active pharmaceutical ingredients (APIs) where stereochemistry plays a critical role in biological activity. Its structure allows for selective transformations, making it valuable in catalysis and the development of enantioselective reactions. Additionally, (S)-SDP is employed in the synthesis of fine chemicals and agrochemicals that require high enantiomeric purity. Its utility in organocatalysis and ligand design further enhances its importance in modern synthetic chemistry.
