Acts by inhibiting biosynthesis of the essential amino acids valine and isoleucine, hence stopping cell division and plant growth. Selectivity derives from rapid metabolism in the crop. Metabolic basis of selectivity in sulfonylureas reviewed (M. K. Koeppe & H. M. Brown, Agro-Food Industry, 6, 9-14 (1995)). Uses: Post emergence control of wild mustard, hempnettle and other broad-leaved weeds in oilseed rape, at 15-20 g/ha. Description： M.F.: C15H18N6O6S Mol Wt: 410.4 Form (appearance): Colourless to light tan, odourless crystals. M.P.: 194℃ V.P.: 7.73 x 10 l0 mpa (25℃) S.G.: 1.6 Solubility.: In water 50 mg/l (pH 7, 25℃). In acetone 1.6, acetonitrile 0.8, ethanol 0.17, methanol 0.35, methylene chloride 3.9, ethyl acetate 0.68 (all in g/l). Stability: Stable at pH 7 and pH 9. Hydrolysis occurs more rapidly at pH 5, DT50 45 d. Photolysis is not a major degradation pathway. Acidic in reaction, Henry: 6.34 × 10-12 Pa m3 mol-1 (calc.) KowlogP: 0.89 (pH 7), 1.588 (pH 5) Pka: 4.6
