Abstract:A method for the 2-methylthio-4-trifluoromethylacetophenone was established using high performance liquid chromatography with fluorescence detector(HPLC-PDA). The samples were dissolved with methanol, using methanol and water(plus 0.2% HAc)as mobile phase, The analysis was performed by HPLC-PDA with an external standard. The results showed that the standard deviation, the coefficient of variation, the average recovery and the liner correlation of method were 0.19, 0.20%, 100.04% and 0.999 6 respectively.
Key words:2-methylthio-4-trifluoromethylacetophenone; high performance liquid chromatography; analysis
