A kind of detection method of residual solvent N,N-diisopropylethylamine in roxadustat |
| abstract |
The invention discloses a method for detecting the residual solvent N,N-diisopropylethylamine in roxadustat. The method adopts a gas chromatography analysis method. In order to reduce the adsorption interference of roxadustat to N,N-diisopropylethylamine, realize the accurate detection of residual solvent N,N-diisopropylethylamine in roxadustat, so as to reach roxadustat The quality of APIs and their preparations is controllable. |
