Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) where stereochemistry plays a critical role in biological activity. Its structure allows for selective interactions in drug molecules, making it valuable in the production of central nervous system agents and other therapeutic compounds. Commonly employed in asymmetric synthesis to introduce chirality, enhancing the efficacy and specificity of final drug products. Also utilized in the preparation of intermediates for agrochemicals and specialty chemicals requiring enantiomeric purity.
