A doubly tethered chiralstationaryphase (CSP) based on (+)-(18-crown-6)-2,3,11,12-tetracarboxylicacid were appli- ed to the liquidchromatographic resolution of racemic tocainide, an antiarrhythmic agent, and its analogues. The chiral recognition efficiency of the doubly tethered CSP for tocainide and its analogues was generally greater than that of the corresponding singly tethered CSP especially
