| Abstract: | A method was established for determining two intermediates in synthesis of imidacloprid,2 chloro 5 methyl pyridine and 2 chloro 5 chloromethyl pyridine by HPLC. Under the optimum condition,the mixture were separated. The concentrations showed good linearity with the HPLC peak areas with correlation coefficients of 0.9996 and 0.9997,respectively.The average recoveries are 100.0 and 99.71%,respectively. |
