| titleOfInvention | Method for the detection of isomers of orlistat intermediates |
| abstract | The present invention relates to a method for detecting isomers of orlistat intermediates. The method is as follows: preparation of reference substance solution: take the enantiomer reference substance of orlistat intermediate, add solvent to dissolve, and obtain enantiomer reference substance solution; preparation of sample solution to be tested: take the sample to be tested , dissolve with solvent to obtain the sample solution to be tested; carry out liquid chromatography detection on the enantiomer reference substance solution and the sample solution to be tested; the chromatographic conditions of the liquid chromatography include: mobile phase A is n-hexane, Mobile phase B is isopropanol, mobile phase C is diethylamine, isocratic elution; in the isocratic elution, keep the volume ratio of the mobile phase A, the mobile phase B and the mobile phase C It was (95±5): (5±2): (0.1±0.05). The above method can effectively separate the chromatographic peaks of the orlistat intermediate and its enantiomers, and provide a simple, accurate, fast and reliable detection method for the industrial production of the orlistat intermediate. |
