[0003] Zhang Liqing et al. mentioned in the article "Reversed Phase High Performance Liquid Chromatography Simultaneously Determination of the Content of 5 Components including Paracetamol" in "Analytical Chemistry", Volume 31, Issue 1, January 2003, that the separation of paracetamol was carried out by liquid phase detection. Aminophenol, chlorpheniramine, caffeine, guaiacol glyceryl ether and p-aminophenol are five substances, but this liquid phase method cannot separate 4-amino-3-fluorophenol and 4-aminophenol, and the detection limit Unable to meet the requirement that genotoxic impurities 4-amino-3-fluorophenol and 4-aminophenol need to be controlled below 9ppm
[0004] Moreover, the retention of 4-amino-3-fluorophenol and 4-aminophenol compounds is weak, and it is easy to produce solvent effect and cause peak bifurcation, thus affecting the accuracy of detection

Abstract

The invention provides a method for detecting p-aminophenols by UPLC-MS / MS; comprising the following steps: a, determining UPLC-MS / MS conditions; b, adopting ultra-high performance liquid chromatography-triple quadrupole mass spectrometry (UPLC-MS / MS) detects respectively reference substance solution, need testing solution; c, obtain the impurity content in the sample with peak area calculation by external standard method. The present invention provides a new detection method for detecting p-aminophenol substances, each object to be tested has no interference with each other, has high sensitivity, and can realize accurate detection of 4-amino-3-fluorophenol and 4-aminophenol at the same time , providing an effective detection method for monitoring the content of p-aminophenols.

Description

technical field [0001] The invention belongs to the field of analytical chemistry, and in particular relates to a method for detecting p-aminophenols by UPLC-MS / MS. Background technique [0002] 4-[4-({[4-Chloro-3-(trifluoromethyl)phenyl]carbamoyl}amino)-3-fluorophenoxy]-N-methylpyridine-2-carboxamide monohydrate The drug is a novel oral multikinase inhibitor for the treatment of patients with metastatic colorectal cancer (CRC), gastrointestinal stromal tumor (GIST) and hepatocellular carcinoma (HCC). The drug has been approved for use in more than 90 countries and regions including the United States, the European Union, and Japan, and was approved for marketing by the CFDA on March 24, 2017, for the treatment of patients with metastatic colorectal cancer and gastrointestinal stromal tumors. The maximum daily dose of the drug is 160mg, and the genotoxic impurities 4-amino-3-fluorophenol and 4-aminophenol need to be controlled below 9ppm. [0003] In "Analytical Chemistry",...
