Abstract

The invention belongs to the technical field of medicine analysis and particularly relates to a quantitative method for 3-aminopiperidine and a detection method for the chiral purity of 3-aminopiperidine. According to the method, benzoyl chloride which is used as a derivatization reagent and 3-aminopiperidine are rapidly derived at a low temperature in a large quantity of organic solvents to generate benzoyl-3-aminopiperidine; then a detection analysis of benzoyl-3-aminopiperidine is carried out by using HPLC-UV (High Performance Liquid Chromatography-Ultraviolet). The method carries out qualitative analysis and quantitative analysis by adopting a common C18 column, and carries out enantiomeric excess rate determination by adopting a chiral chromatographic column. The method is simple to operate, high in sensitivity and high in accuracy, is easy for standardized operation.

Description

technical field [0001] The invention belongs to the technical field of drug analysis, and in particular relates to a qualitative and quantitative method for 3-aminopiperidine and a high-performance liquid chromatography analysis method for its chiral purity. Background technique [0002] 3-aminopiperidine is an important intermediate of linagliptin, establish and confirm the qualitative and quantitative methods and chirality of 3-aminopiperidine ee The value determination method is of great significance to the detection and monitoring of 3-aminopiperidine. The HPLC detection method has the advantages of high detection sensitivity, high precision, less time required for detection, and high repeatability of detection results. It is a commonly used detection method in current analytical chemistry. Meek et al.
