Used as an intermediate in the synthesis of chiral pharmaceuticals, particularly in the production of beta-blockers and other bioactive molecules. Its stereochemistry allows for selective reactions in asymmetric synthesis, making it valuable in developing enantiomerically pure drugs. Commonly employed in organic synthesis to introduce chiral centers via alkylation or condensation reactions. Also utilized in the preparation of prodrugs and enzyme inhibitors where controlled stereochemistry is critical for biological activity.
