Used as a chiral auxiliary and resolving agent in organic synthesis, particularly for the separation of enantiomers in pharmaceutical intermediates. Its asymmetric center enables stereoselective reactions, making it valuable in the production of single-enantiomer drugs. Commonly employed in the preparation of chiral amines and in catalysis where stereocontrol is required. Also utilized in the development of chiral ligands for asymmetric hydrogenation and other enantioselective transformations. Due to its volatility and basicity, it is sometimes used in analytical applications such as chiral derivatization for GC or HPLC analysis.
