A kind of detection method for potential genotoxic impurity of sodium carboxysulfonate |
| abstract |
The invention provides a method for detecting potential genotoxic impurities of sodium carboxysulfonate. The detection method adopts gas chromatography to detect genotoxic impurities in a sample to be tested. The sample to be tested is a raw material and preparation of sodium carboxysulfonate. The genotoxic impurities are one or more combinations of semicarbazide, chloroacetic acid, and N,N-dimethylnitrosamine. The detection method of the invention, which simultaneously separates and determines the potential genotoxic impurities of sodium carboxylate and its preparation, has extremely important significance for the quality control of sodium carboxylate and its preparation. |
