Physical & Safety Data

Physical Properties

Molecular weight:421.7; Physical form:Yellow to orange, odourless crystals. Density:1.54; Melting point:101.0-103.0 °C; ( tech., 92.4-103.8 °C); Vapour pressure:3.2 ×10-2 mPa (25 °C) ( OECD 104); Henry constant:0.19 Pa m3 mol-1 ( calc.); Partition coefficient(n-octanol and water):logP = 5.45 (25 °C); Solubility:In water 0.07 mg/l (25 °C). In acetone 560, toluene 400, ethanol 18, n-hexane 14, n-octanol 6.8 (all in g/l, 25 °C).; Stability:Decomposes exothermically above 250 °C. Hydrolytically stable between pH 5 and pH 9.

Toxicology

Oral:Acute oral LD₅₀ for rats >5000 mg/ kg. Percutaneous:Acute percutaneous LD₅₀ for rats >2000 mg/kg. EC formulation (150 g/l) is a moderate skin irritant and an extreme eye irritant. Inhalation: LC₅₀ for rats >2130 mg/m³. Phytotoxicity:May cause some injury to immature plants. ADI:( JMPR) 0.004 mg/ kg b.w. [1996].

Environmental Profile

Ecotoxicology:
Algae: EC₅₀ for Selenastrum >0.85 mg/l.Bees:Non-toxic.Birds: LD₅₀ for bobwhite quail and mallard ducklings >2000 mg/kg. LC₅₀ for mallard ducklings and bobwhite quail >5000 ppm.Daphnia: LC₅₀ (48 h) >66 μg/l. Fish:Toxic to fish; LC₅₀ for bluegill sunfish 18, trout 25 μg/l.Worms: LC₅₀ for earthworms >1000 mg/ kg.Other aquatic spp.:E_dC₅₀ for Lemna gibba 0.15 mg/l.

Environmental fate:
Animals:Metabolic reactions include reduction of the nitro groups, acetylation of the amino groups and hydroxylation of the phenyl ring.Soil:Strongly adsorbed and therefore immobile in soil; degradation is by photolysis. Stable to hydrolysis at 5, 7 and 9.Plant:Metabolism in tobacco is rapid and extensive; reduction or complete removal of substituents occurs.
