Ethyl S-(+)-4-cyano-3-hydroxybutyrate (Cat No.: R008153) is a chiral β-hydroxy ester featuring a cyano group and a defined stereocenter, making it a valuable intermediate in asymmetric synthesis. It is commonly used in the preparation of statins and other biologically active molecules, where stereochemistry is critical for activity. The ethyl ester enhances solubility and reactivity in organic solvents, while the cyano group allows for further functional transformations. Its enantiomeric purity supports efficient synthesis of pharmaceutical agents with improved potency and selectivity.
