Use

Hydrolysis of pyrazolate (DTP) in buffer solutions and in artificial gastric and intestinal fluids proceeds predominantly through base- and acid-catalyzed processes in the regions above pH 7 and below pH 3, respectively, whereas both processes occur between pH 3 and pH 7. The hydrolysis products are p- toluenesulfonic acid and 4-(2,4-dichlorobenzoyl)-1,3- dimethyl-5-hydroxypyrazole. The metabolism study of DTP in fish, rats, plant, soils, and soil microorganisms shows that the metabolites in these systems are mostly derived from the herbicidal entity of pyrazolate resulting from N-demethylation and hydroxylation followed by further oxidation of the methyl group of the pyrazole ring and the cleavage of the carbonyl linkage (see Nakagawa et al.).
