The hydrolysis of the sulfonylurea herbicide triasulfuron [(2-(2-chloroethoxy)-N-[[4-methoxy-6-methyl-1,3,5-triazin-2-yl)amino]carbonyl]benzenesulfonamide] was studied in aqueous buffers of pH values 2, 3, 4, 5, 6, 7, and 9. The reaction was of first-order and pH-dependent. Triasulfuron was more persistent in neutral or weakly basic than in acidic solution Five metabolites have been isolated and identified. At all pH values studied, the primary pathway of degradation was the cleavage of the sulfonylurea bridge. However, minor degradation pathways have also been observed like O-demethylation and opening of the triazine ring. The product distribution was pH-dependent. In the experiment, the researchers used many compounds, for example, 2-(2-Chloroethoxy)benzenesulfonamide (cas: 82097-01-6Quality Control of 2-(2-Chloroethoxy)benzenesulfonamide).
2-(2-Chloroethoxy)benzenesulfonamide (cas: 82097-01-6) belongs to amides. Because of the greater electronegativity of oxygen, the carbonyl (C=O) is a stronger dipole than the NâC dipole. The presence of a C=O dipole and, to a lesser extent a NâC dipole, allows amides to act as H-bond acceptors. The presence of the amide group âC(=O)Nâ?is generally easily established, at least in small molecules. It can be distinguished from nitro and cyano groups in IR spectra. Amides exhibit a moderately intense νCO band near 1650 cmâ?. By 1H NMR spectroscopy, CONHR signals occur at low fields. In X-ray crystallography, the C(=O)N center together with the three immediately adjacent atoms characteristically define a plane.Quality Control of 2-(2-Chloroethoxy)benzenesulfonamide
