Ethyl (R)-(-)-4-Cyano-3-Hydroxybutyrate (CAS: 141942-85-0) is used in a biocatalytic process for the synthesis of an Atorvastatin Calcium (CAS: 134523-03-8) intermediate and degredation products/impurities. Ethyl (R)-(-)-4-Cyano-3-Hydroxybutyrate is an important intermediate for the synthesis of HMG-CoA reductase inhibitors. If it is used as a raw material, synthetic Atorvastatin is mainly used for the treatment of hypercholesterolemia and mixed hyperlipidemia, coronary heart disease and stroke. Atorvastatin Calcium is a statin-class medication used mainly for lowering the lipid as well as preventing the event associated with cardiovascular disease.
