Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the production of enantiomerically pure drugs. It plays a crucial role in the development of compounds with specific biological activities, such as central nervous system agents or cardiovascular drugs. Its application extends to asymmetric synthesis, where it helps create optically active intermediates for complex organic molecules. Additionally, it is employed in research and development for designing new therapeutic agents with improved efficacy and reduced side effects.
