| PYRAZOLATE Usage And Synthesis |
| Uses | Pyrazolynate is a 4-benzoyl pyrazole molecule used for
the selective control of annual and some perennial grass and broadleaf weeds in paddy rice in the Far East (as Sanbird) (20). | | Metabolic pathway | 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.). |
