Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of active ingredients for central nervous system (CNS) drugs. Its chiral structure makes it valuable in producing enantiomerically pure compounds, which are critical for enhancing drug efficacy and reducing side effects. Commonly employed in the preparation of dopamine modulators and agents targeting neurological disorders such as Parkinson’s disease and restless legs syndrome. Also utilized in research settings for structure-activity relationship (SAR) studies of phenylpropylamine derivatives.
