Flecainide, an antiarrythmic agent, and its analogs were resolved on a high performance liquid chromatographic chiral stationary phase (CSP) based on (+)‐(18‐crown‐6)‐2,3,11,12‐tetracarboxylic acid with the use of a mobile phase consisting of methanol‐acetonitrile‐trifluoroacetic acid‐triethylamine (80/20/0.1/0.3, v/v/v/v). The chiral resolution was quite successful, the separation factors (α) and
抗心律失常药Flecainide及其类似物在使用的高效液相色谱手性固定相(CSP)上进行拆分,该固定相基于(+)-(18-crown-6)-2,3,11,12-四羧酸流动相的组成为甲醇-乙腈-三氟乙酸-三乙胺(80/20 / 0.1 / 0.3,v / v / v / v)。手性拆分非常成功,分离因子(α)和拆分度(R S)包括氟卡尼在内的20种分析物的范围分别为1.19–1.82和1.73–6.80。发现分析物的苯甲酰基基团的邻位取代基会导致分析物的保留时间减少,这可能是由于邻位取代基所施加的位阻引起的分析物的构象变形。《手性》,2010年。©2009 Wiley-Liss,Inc.。
