| Abstract: | The HPLC method for the determination of tetrafluorobenzyl acid was studied.Analytical conditions involved were as follows： using a ODS-C18 reversed-phase chromatography column,with a mobile phase of 15% methanol and 85%（20mmol/L KH2PO4,pH=2.3）（by vol）,and the flow rate of 1.0mL/min.Wavelength of the UV detector was 276nm.The mobile phase choice was studied,at the same time,the linear correlation,the variation coefficient,the standard deviation and the recovery rate of the method were studied also.Under the given conditions,the quantitatively determination of tertrafluorobenzoic acid can be easily realized. |
