摘要
氯氟氰虫酰胺(cyhalodiamide)[3-氯-N1-(2-甲基-4-七氟异丙基苯基)-N2-(1-甲基-1-氰基乙基)邻苯二甲酰胺]是由浙江省化工研究院有限公司自主开发的邻苯二甲酰胺类新型杀虫剂。本文采用高效液相色谱法,以甲醇∶水(70∶30)为流动相,使用ZORBAX SB-C18、5μm为填料的不锈钢柱和二极管阵列检测器,在210nm波长下对氯氟氰虫酰胺悬浮剂进行分离和定量分析。结果表明,该分析方法的线性相关系数为0.999 9,标准偏差为0.024,变异系数为0.119%,平均回收率为99.93%。
Cyhalodiamide {3-chloro-N2-1-methyl-1-cyano-ethyl-N1-[2-methyl-4-(1,2,2,2-tetrafluoro-1-trifluoromethyl-ethyl)-phenyl]-phthalamide} is a novel insecticidal phthalic diamides developed by Zhejiang Research Institute of Chemical Industry Ltd, China. A method for separation and the quantitative analysis of cyhalodiamide by HPLC with methanol and water( 70 ∶30) as mobile phase, ZORBAX SB-C18 column and DAD at 210 nm wavelength was described. The result showed that the linear correlation coefficient was 0.999 9, the standard deviation was 0.024, the variation was 0.119%, and the average recovery was 99.93%.
