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 supports the formation of complex molecules in asymmetric synthesis, making it valuable in the production of enantiomerically pure drugs. Commonly employed in the manufacture of central nervous system agents, antiviral medications, and other therapeutic compounds requiring high enantiomeric purity. Also utilized in research and development for creating novel drug candidates due to its versatile reactivity and ability to form stable intermediates.
