Used as a chiral derivatizing agent in the analysis of enantiomeric purity, particularly in stereoselective synthesis and pharmaceutical research. Its anthracene moiety allows for strong UV and fluorescence detection, making it valuable in high-performance liquid chromatography (HPLC) for separating and quantifying enantiomers. Commonly employed in the development and quality control of chiral drugs where precise stereochemical determination is critical. Also serves as a building block in asymmetric synthesis for creating bioactive molecules with defined stereochemistry.
