代謝経路

The hydrolytic degradation of thifensulfuron methyl is pH dependent and, in alkaline condition, specifically yields the corresponding free acid. Primary degradation cleaves the sulfonylurea moiety to give two typical hydrolyzed products, sulfonamide and aminotriazine analogs, derived from thifensulfuron methyl in acidic and neutral conditions. Hydrolysis of the ester linkage proceeds in mammals, plants, soils, and also chemical hydrolysis, and opening of the triazine ring occurs to yield the acetyltriuret analog identified. On the other hand, by hydrolysis, O- demethylated thifensulfuron methyl undergoes opening of the triazine ring to give the corresponding acetyltriuret analog. Under photolytic conditions, methyl 3-(4-methoxy-6-methyl-1,3,5-triazin-2- yl)aminothiophene-2-carboxylate is identified.
