Used in pharmaceutical research as a chiral building block for the synthesis of enantiomerically pure compounds. It is particularly valuable in the development of drugs targeting neurological disorders, where stereochemistry plays a critical role in efficacy. Also employed in asymmetric catalysis to produce optically active intermediates. Its naphthalene moiety enhances binding affinity in receptor studies, making it useful in biochemical assays. Additionally, it serves as a precursor in the synthesis of complex molecules for medicinal chemistry and drug discovery.
