Problems solved by technology

[0013] Apixaban and its intermediate II are weakly polar compounds, and the impurities in them are usually detected by reversed-phase high-performance liquid chromatography. For example, the quality standard of apixaban tablets uses octadecylsilane bonding Reversed-phase high-performance liquid chromatography with silica gel as a filler is used to detect related substances in apixaban tablets. This method uses gradient elution, the mobile phase preparation is complicated, the system equilibrium time is long, and the operation is cumbersome. It is used for the intermediate II. Detection, the peak is too fast, not suitable for the quality control of intermediate II

Abstract

The invention belongs to the field of analysis detection, and relates to a method for detecting an Apixaban intermediate II through a reversed-phase high-performance liquid chromatogram. The method includes the following steps of firstly, preparing a test solution; secondly, detecting the test solution through the reversed-phase high-performance liquid chromatogram; thirdly, calculating the content of each single impurity and all the impurities in the test solution according to an area normalization method. By means of the method, through simple mobile-phase components, the intermediate II can be completely separated from chromatographic peaks of all the impurities; meanwhile, the method is accurate and reliable in detection result and provides possibility for controlling the quality of the intermediate product in the Apixaban synthesis process.
