The synthesized [Cu(mal)(bpy)]\u22c5H<jats:sub>2<\/jats:sub>O and MOFs\u2010modified capillary column were characterized by X\u2010ray diffraction, thermogravimetric analysis, particle size distribution analysis, nitrogen absorption characterization, FTIR spectroscopy, SEM, and energy\u2010dispersive X\u2010ray spectroscopy (EDX). The MOFs\u2010modified capillary column was used for the stereoisomer separation of some drugs. The LODs and LOQs of six analytes were 0.1 and 0.25 \u03bcg\/mL, respectively. The linear range was 0.25\u2013250 \u03bcg\/mL for ephedrine, 0.25\u2013250 \u03bcg\/mL for pseudoephedrine, 0.25\u2013180 \u03bcg\/mL for <jats:sc>d<\/jats:sc>\u2010penicillamine, 0.25\u2013120 \u03bcg\/mL for <jats:sc>l<\/jats:sc>\u2010penicillamine, 0.25\u2013180 \u03bcg\/mL for <jats:sc>d<\/jats:sc>\u2010phenylalanine, and 0.25\u2013160 \u03bcg\/mL for <jats:sc>l<\/jats:sc>\u2010phenylalanine, all with <jats:italic>R<\/jats:italic><jats:sup>2<\/jats:sup> &gt; 0.999.
