The syntheses of four hydrolysis products, 2-F₃C(CH₂)₂C₆H₄SO₂NHCOR (R = NHCONHCONHAc, NHCONHCONH₂, NHCONH₂, NH₂), isolated from environmental studies on the title compound (CGA-152005) are reported. Spectral comparison of these synthetic standards with study isolates provided proof for sulfonyl urea intact triazine ring hydrolysis.

Hultgren, Ryan P. published the artcileEffects of Soil pH and Soil Water Content on Prosulfuron Dissipation, Product Details of C9H10F3NO2S, the publication is Journal of Agricultural and Food Chemistry (2002), 50(11), 3236-3243, database is CAplus and MEDLINE.

The sulfonylurea herbicide prosulfuron is used for the selective control of broadleaf weeds in corn, sorghum, and cereal grains. To investigate its fate in soils, this study examined the effects of soil pH and water content on the rates of dissipation processes and the products formed under aerobic conditions. Radiometry and chromatog. analyses were used to quantify the degradation products and bound residues formed in incubations of 10 different soils. The pH-dependent hydrolysis of the sulfonylurea bridge to form Ph sulfonamide was the primary transformation process. Significant microbial degradation of prosulfuron occurred in 2 of the 10 soils, yielding ¹⁴CO₂ and desmethyl prosulfuron among the major products. The time required for 50% dissipation of the herbicide (DT₅₀) was determined for each soil and water content treatment. At equivalent water contents, prosulfuron DT₅₀ values were pos. correlated with soil pH (P < 0.0001), varying from 6.5 days at pH 5.4 to 122.9 days at pH 7.9. Soil pH and water content strongly influence the fate of sulfonylurea herbicides in agricultural fields. Differences in the effect of soil water content on dissipation kinetics in a comparison of two soils were attributed to differences in soil pH, texture, and the ability of indigenous microorganisms to transform the herbicide.

Bray, Leslie D. published the artcileHydrolysis of prosulfuron at pH 5: evidence for a resonance-stabilized triazine cleavage product, HPLC of Formula: 94125-42-5, the publication is Pesticide Science (1997), 51(1), 56-64, database is CAplus.

Prosulfuron is a herbicide for the selective control of broadleaf weeds in corn. In order to exam. the effect of pH on the stability of prosulfuron in aqueous solution, a hydrolysis experiment was conducted in buffer at pH 5, 7 and 9 utilizing [phenyl-¹⁴C] and [triazine-¹⁴C]prosulfuron. Prosulfuron was found to be stable under neutral and basic conditions and hydrolytically unstable under acidic conditions (T_1/2 ∼ 10 days). One of the major routes of degradation at pH 5 involved hydrolysis of the sulfonylurea bridge to yield the corresponding phenyl- and triazine-cleavage products and minor amounts of desmethyl-prosulfuron and dihydroxymethyltriazine. In addition to these hydrolysis products, an unknown species was observed at significant levels after 30 days (∼20% of the applied dose). A large-scale experiment was subsequently performed to generate addition material for the spectroscopic characterization and identification of this unknown degradate. A thorough spectral evaluation of this unknown revealed a resonance-stabilized derivative of the parent mol. which stemmed from a hydrolytic opening of the triazine ring of desmethyl-prosulfuron. Although this triazine ring-opening phenomenon was first described for chlorsulfuron, a structurally related sulfonylurea herbicide, the structure of the product was only postulated. Recently, Cambon et al. described the hydrolysis kinetics of thifensulfuron and thifensulfuron-Me which resulted in cleavage of the sulfonylurea bridge and triazine ring-opening. The results support these findings and the characterization and identification of this resonance-stabilized species were described by comparison with the recently synthesized authentic reference standard
