Abstract

The invention discloses a method for detecting impurities in propadiene diethyl phosphate, which relates to the field of chemical drug analysis, and adopts a triple quadrupole mass spectrometry detector to detect in an ESI positive ion mode and an MRM multi-reaction monitoring mode. According to the present invention, the multi-reaction monitoring mode (MRM) of the high performance liquid chromatography-mass spectrometry is adopted to detect the propadiene diethyl phosphate, such that the sensitivity is high, the specificity is strong, and the propadiene diethyl phosphate in the fosfomycin sodium can be effectively controlled to the toxicological threshold value (TTC), namely 1.5 [mu] g/day.

Description

technical field [0001] The invention relates to the field of chemical drug analysis, in particular to a method for detecting impurities of allene diethyl phosphate. Background technique [0002] In the synthetic route of fosfomycin sodium, when the hydrolysis reaction of the intermediate is not complete, after adding ethanol, diethyl allene phosphate may be produced. The toxicity parameters of allene diethyl phosphate were comprehensively predicted by the ADME / T property prediction software ADMETPredictorTM (version 9.5.0.16) of Simulations Plus Company in the United States. This impurity may produce genotoxicity and belong to genotoxic impurities. [0003] Genotoxic impurities (also called genotoxic impurities) usually refer to substances that can cause DNA mutation, chromosome breakage or DNA recombination. Because genotoxic impurities can induce gene mutation and lead to chromosome breakage and rearrangement at very low concentrations, they have potential carcinogenicity...
