Physical PropertiesMolecular weight:293.5; Physical form:Colourless powder. Density:1.69 (20 °C); Melting point:95-97 °C; Vapour pressure:0.053 mPa (20 °C); Henry constant:4×10-4 Pa m3 mol-1 (calc.); Partition coefficient(n-octanol and water):logP = 2.9; Solubility:In water 35 mg/l (20 °C). In acetone 460, dichloromethane 170, hexane 89, benzene 72, isopropanol 12 (all in g/kg, 20 °C).; Stability:Slowly hydrolysed in neutral, slightly acidic, and slightly alkaline media.
-
ToxicologyOral:Acute oral LD50 for rats >5000 mg/kg. Percutaneous:Acute percutaneous LD50 for rats >2000 mg/kg, rabbits >10 000 mg/kg. Not a skin or eye irritant. Inhalation:LC50 (6 h) for rats >1.05 mg/l air. Phytotoxicity:A number of crops may be injured by pre-emergence applications, e.g. rice, beet, okra, flax, cucurbits, tomatoes, strawberries, etc.
-
Environmental ProfileEcotoxicology: Bees:Not toxic to bees.Birds:Dietary LC50 (10 d) for pheasants and mallard ducks >10 250 mg/kg diet.Fish:LC50 (96 h) for rainbow trout 5, bluegill sunfish 5, crucian carp 8 mg/l. Environmental fate: Soil:In biologically active soils, DT50 8-28 w; strongly bound to soil (Koc 908), indicating low leaching potential. In water, stable against abiotic degradation, but in biologically active systems. Plant:In plants, metabolism involves demethylation and deamination-decarboxylation to the corresponding aniline molecule.
