A doubly tethered chiral stationary phase (CSP) based on (+)-(18-crown-6)-2,3,11,12-tetracarboxylic acid were appli- ed to the liquid chromatographic 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
将基于 (+)-(18-crown-6)-2,3,11,12-四羧酸的双键手性固定相 (CSP) 应用于抗心律失常药物外消旋妥卡尼的液相色谱分离中,及其类似物。双束缚 CSP 对妥卡尼及其类似物的手性识别效率通常高于相应的单束缚 CSP,尤其是在分辨率 (RS) 方面。托卡尼及其类似物在双束缚 CSP 上的分离度取决于水性流动相中有机和酸性改性剂的含量和类型以及柱温。尤其,
