Physical Properties
Molecular weight:357.8; Physical form: Odorless, white crystalline solid. Density:1.48; Melting point:174-178 °C; Vapour pressure:3×10-6 mPa (25 °C); Henry constant:3.0×10-9 Pa m3 mol-1; Partition coefficient(n-octanol and water):logP = -0.99 (pH 7); pKa:3.6; Solubility:In water 587 ppm (pH 5), 3.18 g/100g (pH 7) (both 25 °C). In dichloromethane 1.4, acetone 4, methanol 15, toluene 3, hexane <0.01 (all in g/l, 20 °C).; Stability:Stable to light when dry. Decomposes at 192 °C. In aqueous solutions, DT50 4-8 w (pH 5.7-7.0, 20 °C); significant degradation in 24-48 h (pH <5). Hydrolysis is also promoted by polar organic sol. Slight solubility in methylene chloride, acetone, methanol, toluene, and hexane.
Toxicology
Oral:Acute oral LD50 for male rats 5545 mg/kg, female rats 6293 mg/kg. Percutaneous:Acute percutaneous LD50 for rabbits 2500 mg/kg. Mild eye irritant; non-irritating and non-sensitising to skin. Inhalation: LC50 (4 h) for rats >5.9 mg/l air. Phytotoxicity:Phytotoxic to many broad-leaved crops, particularly sugar beet and brassicas. ADI:(JMPR) 0.01 mg/kg b.w. [1992].
Environmental Profile
Ecotoxicology: Bees:LD50 (contact) >25 mg/bee.Birds:Acute oral LD50 for mallard ducks and bobwhite quail >5000 mg/kg. Dietary LC50 (8 d) for mallard ducks and bobwhite quail >5000 mg/kg diet.Daphnia:LC50 (48 h) 370 mg/l.Fish:LC50(96 h) for rainbow trout >250, bluegill sunfish >300 mg/l. LC50 for fathead minnow >300, catfish >50, sheepshead minnow >980 mg/l.Worms: LC50 >2000 mg/kg. Environmental fate: Soil:In soil, deactivation is through hydrolysis followed by complete metabolism to low-molecular-weight compounds through normal soil microbial processes. Rate of hydrolysis is increased at lower pH. Average half-life under growing-season conditions is c. WATER SOLUBILITY: 300-2800 ppm at 25°C (pH 5-7)
Transport Information
Signal Word:CAUTION; Hazard Class:III (Slightly hazardous)
