Abstract

The invention belongs to the field of analytical chemistry and relates to a method for separating and measuring acitretin and its genotoxic impurities. The reagent composition used for solid-liquid separation and determination of acitretin and its genotoxic impurities is: an acidic aqueous solution system and an organic solvent; the method for using the above-mentioned reagent composition acitretin and its genotoxic impurities is: take the test sample and dissolve it in Tetrahydrofuran is diluted with a diluent to obtain a sample solution; the mobile phase is prepared; the sample solution is injected into the separation detection system, and the eluent is obtained by eluting and separating the sample solution with the flow; the eluent enters the detection system device measurement. The present invention can completely separate the acitretin and its genotoxic impurities at the same time, the solvent peak in the detection does not interfere with the determination of the acitretin and its genotoxic impurities, and the separation degree is greater than 1.5; and the method is simple, high in sensitivity and short in analysis time, With strong specificity and good reproducibility, it can simultaneously effectively separate and highly sensitively (up to ppm level) determine the content of genotoxic impurities in acitretin raw materials and preparations.

Description

technical field [0001] The invention belongs to the field of analytical chemistry, in particular to a method for separating and measuring acitretin and its genotoxic impurities. Background technique [0002] Active pharmaceutical ingredients often contain impurities, including residues and degradation products of raw materials and intermediates used in the synthetic process. Due to their intrinsic activity, some raw materials, intermediates or by-products may be known or suspected mutagens and / or carcinogens. In addition, previously impossible human exposure and risk characterization of genotoxic impurities is now possible with advances in analytical techniques. Assuming that minimization of human exposure is accompanied by minimization of the risk of genotoxic impurities, the availability of high-sensitivity assays is accompanied by increased concerns about the measurement and control of suspected API residues of genotoxic impurities. [0003] Genotoxic impurities (or gen...
