Physical & Safety Data

Physical Properties

Molecular weight:347.3; Physical form:Colourless, odourless, crystalline powder. Density:1.52 g/cm3 (20 °C); Melting point:93 °C; Vapour pressure:0.2 mPa (20 °C); Henry constant:7.7 × 10-2 Pa m3 mol-1 ( calc.); Partition coefficient(n-octanol and water):logP = 3.90 (20 °C); Solubility:In water 0.9 mg/l (20 °C). In heptane 54, dichloromethane >250, isopropanol 22, xylene 190 (all in g/l, 20 °C).; Stability:Hydrolysis DT50 (22 °C) 12 d ( pH 4), 29 h (pH 7), <10 min ( pH 9). Under environmental conditions, hydrolysis occurs much more rapidly than photolysis.;

Toxicology

Oral:Acute oral LD₅₀ for rats >5000, mice >1000, guinea pigs 250-500 mg/kg. Percutaneous:Acute percutaneous LD₅₀ for rats >5000 mg/kg. Severely irritating to skin and moderately irritating to eyes (rabbits). Skin sensitiser. Inhalation: LC₅₀ (4 h) for rats c. 0.265 mg/l air (aerosol).

Environmental Profile

Ecotoxicology:
Algae: E_rC₅₀ for Scenedesmus subspicatus >1.0 mg/l.Bees:Non-toxic to bees.Birds: LD₅₀ for Japanese quail >5000 mg/kg. Dietary LC₅₀ (5 d) for bobwhite quail >5000 mg/kg.Daphnia:LC₅₀ (48 h) 0.57 mg/l.Fish:LC₅₀ (96 h) for golden orfe 0.06, rainbow trout 0.05 mg/l.Worms: LC₅₀ for Eisenia foetida >1000 mg/kg dry soil.

Environmental fate:
Animals:In animals, ¹⁴C-tolylfluanid is rapidly absorbed and the radioactivity excreted; there is no accumulation in organs and tissues. Tolylfluanid is rapidly hydrolysed to DMST (dimethylamino sulfotoluidide) and then transformed to the main metaboliSoil:In soil, tolylfluanid is rapidly hydrolysed to DMST (see above) with DT₅₀ 2-11 d. DMST is further degraded to methylaminosulfotoluidide, 4-(dimethylaminosulfonylamino) benzoic acid, 4-(methylaminosulfonylamino)benzoic acid and fiPlant:In plants, tolylfluanid is rapidly hydrolysed to DMST (see above) which is further hydroxylated and conjugated.
