| Hazard Information | Back Directory | [Chemical Properties]
The pure product is white needle-shaped crystals. Its mp is 147-148°C, its vapor pressure is 4.79×10-6 Pa (20°C), and its solubility in 100 mL of acetone, benzene, and dichloromethane is 5 g, 2.4 g, and 4.3 g, respectively. Its solubility in water is 10 mg/L. It is stable at room temperature but decomposes in the presence of acids and bases at elevated temperatures. Its half-life in soil is approximately 30 days. | [Uses]
Herbicide. | [Definition]
ChEBI: A member of the class of ureas that is N-methyl urea substituted by a 3-chloro-4-methylphenyl group at position 3 and a methyl group at position 1. A herbicide that is non-toxic to honeybees but is moderately toxic to mammals, birds, ea
thworms and most aquatic organisms. | [Metabolism]
Chlortoluron is rapidly
metabolized in winter wheat. Hydroxylation of the methyl
group on the phenyl ring has been demonstrated as a
detoxification mechanism for chlortoluron resistance in
winter wheat, whereas in the susceptible weed blackgrass
(Alopecurus myosuroides Huds.), the main metabolite is
the mono N-demethylated metabolite (107). In a tolerant
weed, Persian speedwell (Veronica persica Poir.), chlortoluron is rapidly transformed to the nonphytotoxic di-N-demethylated metabolite (107). |
