Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) requiring high enantiomeric purity. Its structure supports the creation of compounds with specific biological activity, especially in central nervous system agents and cardiovascular drugs. Commonly employed in asymmetric synthesis to introduce chirality, enhancing drug efficacy and reducing side effects. Also utilized in the preparation of intermediates for agrochemicals and specialty chemicals where stereochemistry plays a critical role in performance.
