Abstract
Abstract The method collaboratively studied is based on 3 steps: free interfering amines are removed by acid extraction; dimethylamine is liberated by alkaline hydrolysis; and the liberated amine is distilled into an absorbing solution and continuously titrated. Interfering byproducts are separately determined by a thin layer chromatographic method. Two samples of metoxuron, the technical active ingredient, and an 80% wettable powder, were analyzed by 18 collaborators from Europe, the United States, and South America; results were satisfactory with an overall coefficient of variation of about 0.8%. Only one outlier was noticed. The method was adopted in 1974 as a full CIPAC method. The method was adopted in 1975 as an official first action AOAC method.
