摘要
采用高效液相色谱法,以甲醇∶乙酸∶水(5 0∶3∶47,V/V)为流动相,采用ODS C18色谱柱和紫外检测器,用外标法对苯异氰酸酯法合成的标题化合物进行定量分析。标准偏差0 . 2 5 3 % ,变异系数0 .5 2 4% ,平均回收率98. 5 %。
A method was established for the determination of 1-(2-chloro-4-pyridyl)-3-phenylurea by HPLC on ODS-C_ 18 column with UV absorbance detector and methanol∶acetic acid∶water( 50∶ 3∶47) as mobile phase.The standard deviation was 0.253%,the RSD was 0.524% and recovery was 98.5%.
