Used as a key chiral intermediate in the synthesis of pharmaceuticals, particularly in the production of statins such as rosuvastatin and atorvastatin, which are widely prescribed for lowering cholesterol. Its stereochemistry allows for high selectivity in reactions, making it valuable in asymmetric synthesis. Also employed in the preparation of other bioactive molecules where a chiral lactone structure is required. Its stability and reactivity profile make it suitable for multi-step synthetic routes in fine chemical and drug development industries.
