一般說明
通过特殊的衍生方法,CHIRALDEX B-DM 中环糊精的浓度在聚硅氧烷载体中显著增加。该固定相对许多游离酸和碱非常有用。B-DM 能够分离可在全甲基化 β 环糊精固定相所分离的大部分物质,但分离度更高。B-DM 的选择性包括了 B-PM 和 B-PH 相的应用,但性能更加出众。
應用
它已用于气相色谱法对麻黄碱、伪麻黄碱、氯化中间体和甲基安非他明进行对映体分离。

The enantiomers of dialkyl 2,3-pentadienedioate undergo interconversion during gas chromatographic separation on chiral stationary phases. In this paper the on-column apparent interconversion kinetic and thermodynamic activation data were determined for dimethyl, diethyl, propylbutyl and dibutyl 2,3-pentadienedioate enantiomers by gas chromatographic
