Used as a chiral building block in the synthesis of pharmaceutical intermediates, particularly in the development of asymmetric catalysts and bioactive molecules. Its rigid phenanthryl group enhances stereoselectivity in reactions, making it valuable in enantioselective synthesis. Also employed in the preparation of ligands for transition metal-catalyzed reactions, improving yield and optical purity in drug manufacturing processes. Shows potential in the design of fluorescent probes due to the inherent fluorescence of the phenanthrene moiety, useful in biochemical imaging and sensor applications.
