Used as a key chiral building block in the synthesis of pharmaceuticals, particularly in the production of statins such as atorvastatin and rosuvastatin, which are widely prescribed for lowering cholesterol. Its stereochemistry allows for high selectivity in asymmetric synthesis, improving the efficiency and purity of the final drug product. Commonly employed in multi-step organic transformations where a protected hydroxy acid functionality with a chlorine substituent is required. Also utilized in the preparation of biologically active molecules and intermediates in fine chemical manufacturing.
