| Abstract: | chlorimuron ethyl was synthesized from 2 amino 4 chloro 6 methoxypyrimidine and 2 ethoxylcarbonyl benzene sulfonyl isocyanate. The further purification and separation by recrystallization and column chromatography gave the certified chlorimuron ethyl sample. The chemical structure was characterized by means of element anlysis, IR, UV vis, 1H NMR and MS. The purity of standard chlorimuron ethyl sample studied was testified to be exceed 99%. |
