摘要

本文采用反相高效液相色谱法（HPLC）测定了14 C -绿磺隆的化学纯度

并分别用高效液相色谱与液体闪烁测量仪联用法（HPLC -LSC）以及薄层层析 -同位素成像分析法（TLC -Isotopeimaginganalysis

TLC -IIA）测定了14 C -绿磺隆的放射化学纯度。实验结果显示

合成的14 C -绿磺隆的化学纯度为 94 .4 %

HPLC -LSC和TLC -IIA法测到的放射化学纯分别为 94 .7%和 94 .9—95 .2 %

所得结果较一致。合成的14 C -绿磺隆的化学结构用LC -MS法进行了验证

结果表明

该14 C -绿磺隆样品与绿磺隆标样的HPLC保留时间相同

总正负分子离子峰和选择离子检测推断的分子量均为 35 7

与绿磺隆的分子量相同。

Abstract

The chemical purity of 14 C-labeled chlorsulfuron was determined by HPLC

its radiochemical purity was measured by HPLC-LSC (Liquid scintillation counter) and TLC-Isotope imaging analysis

respectively. The results showed that the chemical and radiochemical purity of synthetic 14 C-chlorsulfuron are 94.4% and 94.7-95.2%

respectively. Results determined by LC-MS showed that the retention time of synthetic 14 C-chlorsulfuron was consistent with that of its standard sample

and the molecular weight determined by MS was 357 that is equal to the molecular weight of chlorsulfuron.
