我们开发了一种简单快速的超临界流体色谱 (SFC) 方法来分离和表征 Ezetimi be 的 R-异构体,方法是使用正相 Chiral Cel OD-H 和 250 mm × 30 mm、5 微米色谱柱,使用含有超临界流体二氧化碳 (Co2) 和 2-丙醇百分比 (85:15) 作为流动相的流动相系统,并在 230 nm 处检测。分离的 R-异构体通过 UV-vis、FT-IR、ESI-MS、HPLC1H 和 13C NMR 进行表征。分离出的R-异构体的纯度约为98%。
A simple and rapid Supercritical Fluid Chromatography (SFC) method has been developed to isolate and characterize R-Isomer of Ezetimi be by using normal phase Chiral Cel OD-H with 250 mm × 30 mm, 5 microns column using a mobile phase system containing super critical fluid carbondi oxide (Co2) and the percentage of 2-Propanol as a mobile phase (85:15) and detection at 230 nm. The isolated R-Isomer is characterized by using UV-vis, FT-IR, ESI-MS, HPLC1H and 13C NMR. The purity of isolated R-Isomer is about 98%.
