Used as a chiral auxiliary in asymmetric synthesis, particularly in the production of enantiomerically pure compounds. It plays a crucial role in the synthesis of pharmaceuticals, where it helps in creating drugs with specific stereochemistry to enhance efficacy and reduce side effects. Additionally, it is employed in the preparation of chiral ligands for catalytic processes, improving the selectivity and yield of chemical reactions. Its application extends to the development of agrochemicals and fine chemicals, where precise stereochemical control is essential for optimal performance.
