General description
CHIRALDEX B-DA 要求分析物具有至少兩種環(huán)狀結(jié)構(gòu),其中一種是連接手性中心的不飽和(芳族)α、β。例如氟西汀、哌醋甲酯和氯苯吡胺。DA 系列對(duì)映立體選擇性主要機(jī)理是被分析物和環(huán)糊精空腔之間合適的包和作用和恰當(dāng)?shù)呐浜?。必須有連接手性中心的可包合基團(tuán) α 或 β 用于手性識(shí)別。由于 CHIRALDEX DA 柱能以高效率分離多環(huán)分析物,因此分析溫度通常高于 150°C。在溫度 >200°C 時(shí)可觀察到對(duì)映立體選擇性(氟西汀乙酰基衍生物)。
