Molecular Structure
Physical Properties
Molecular weight:225.3; Physical form:Colourless crystals; ( tech. is a yellow oil with a mercaptan-like odour). Density:1.231 (20 °C); Melting point:33.4 °C; Flash point:123 °C; Vapour pressure:0.45 mPa (20 °C); 0.94 mPa (25 °C); 26 mPa (50 °C); Partition coefficient(n-octanol and water):logP = 2.04; Solubility:In water 1.8 g/l (20 °C). In dichloromethane, isopropanol and toluene >200, hexane 5-10 (all in g/l, 20 °C).; Stability:Stable in neutral and acidic media, but hydrolysed in alkaline solution. In isopropanol/water (1:1), DT50 (37-40 °C) 330 d ( pH 2), 450 h ( pH 7), 5 min ( pH 11.4);
Toxicology
Oral:Acute oral LD50 for male and female rats c. 200, male and female mice c. 240, female dogs >50 mg/ kg. Percutaneous:Acute percutaneous LD50 for male and female rats >1000 mg/kg. Non-irritating to skin and eyes (rabbits). Not a skin sensitiser. Inhalation: LC50 (4 h) for male and female rats >0.2 mg/l air (for aerosol). Phytotoxicity:Phytotoxic to anthurium and begonias. ADI:( JMPR) 0.05 mg/ kg b.w. [1997].
Environmental Profile
Ecotoxicology: 
Algae: ErC50 for Scenedesmus subspicatus 43 mg/l.Bees:Not toxic to bees.Birds:Acute oral LD50 for Japanese quail 155, mallard ducks 140-275 mg/ kg.Daphnia: LC50 (48 h) 0.22 mg/l.Fish: LC50 (96 h) for rainbow trout 12.8, golden orfe 61.8 mg/l.Worms: LC50 for Eisenia foetida 262 mg/ kg dry soil. 

Environmental fate: 
Animals:In animals, 14C-ethiofencarb is rapidly excreted. The main metabolites are ethiofencarb sulfoxide and sulfone, ethiofencarb phenol and the corresponding sulfoxide and sulfone. Metabolism of carbamate insecticides is reviewed (M. Cool & C. K. JaSoil:Ethiofencarb has a relatively high mobility in soil, but is very rapidly degraded to its sulfoxide and sulfone and hydrolysed to the corresponding phenolic metabolites.Plant:In plants, metabolites include ethiofencarb sulfoxide and sulfone and the hydrolysed products ethiofencarb phenol-sulfoxide and sulfone, which form conjugates."
Transport Information
Signal Word:WARNING; Hazard Class:II(Moderately hazardous)
