The detection method comprises the following steps: using a high performance liquid chromatography instrument to detect and an area normalization method to perform quantitative analysis, and controlling chromatographic conditions to be that the chromatographic column is Agilent ZORBAX SB-phenyl; the injection volume is 5 to 10 [mu]l; the flow velocity is 0.8 to 1.2 ml / min; the column temperature is 25 to 35 DEG C; the detection wavelength is 250 to 300 nm; the mobile phase comprises a mobile phase A which is a 0.1% formic acidaqueous solution and a mobile phase B which is acetonitrile in a volume ratio of (5-70): (30-95); the diluent comprises acetonitrile and water in a volume ratio of (40-60): 50; the detector is a UV detector; the detection method of Vonoprazan fumarate, disclosed by the invention, can simply, accurately, rapidly, efficiently and reliably detect the purity and impurities of 5-(2-fluorophenyl)-N-methyl-1-(3-pyridylsulfonyl)-1H-pyrrole-3-methylamine fumarate, has very high sensitivity, is simple and convenient in operation, can realize complete separation, and further provides the basis for the research, development and quality detection of the compound.

Description

technical field [0001] The invention belongs to the technical field of analytical chemistry, and in particular relates to a detection method of vonoprazan fumarate. Background technique [0002] Vonoprazan fumarate, its chemical name is 5-(2-fluorophenyl)-N-methyl-1-(3-pyridylsulfonyl)-1H-pyrrole-3-methylamine fumarate , is a potassium ion competitive acid blocker (P-CAB) developed by Takeda Pharmaceutical Company. In vitro experiments have shown that the ability of the compound to inhibit the proton pump is 400 times that of lansoprazole, and its relative to Na + ,K + - The inhibitory selectivity of ATPase is more than 1000 times, which can effectively inhibit the secretion of gastric acid and has the advantage of long duration. The purity of the compound and the impurities contained therein will directly affect its function of suppressing acid and treating gastric acid-related diseases. [0003] At present, there is no relevant literature on the purity detection method ...
