During the detection of the liquid chromatography, a mobile phase adopts the following gradient elution procedure: time (min), mobile phase A (%) and mobile phase B (%) 047-5153-492547-5153-492695-1005-03695-1005-036.147-5153-494547-5153-49. According to the technical scheme, the problem that an elution system adopted in a detection method in the prior art cannot obtain qualified specificity in the determination of the pyrazolopyrimidine benzenesulfonate impurities is solved; th
