Used as a chiral derivatizing agent in the resolution of enantiomers, particularly in high-performance liquid chromatography (HPLC). Its structure allows for strong UV detection due to the nitrophenyl group, making it effective for detecting and analyzing chiral compounds in pharmaceutical and analytical chemistry. Commonly applied in the separation of racemic mixtures where precise enantiomeric identification is required. Also employed in asymmetric synthesis as an intermediate for bioactive molecules, leveraging its stereochemical purity to influence the outcome of stereoselective reactions.
