Molecular Structure
Category
Activity
Herbicide
Premix
Emulsifiable concentrate, wettable powder. 
Premix Parters: cacodylic acid sodium cacodylate; 2,4-D dicamba mecoprop; 2,4-D diuron; diuron; fluometuron;
Physical Properties
Molecular weight:214.6; Physical form:Colourless crystals. Density:1.3 (20 °C); Melting point:80-83 °C; Vapour pressure:1.3 (20 °C); 100 (50 °C); Henry constant:5.649 ×10-4 (22 °C); 7.302×10-4 (25 °C) Pa m3 mol-1; Partition coefficient(n-octanol and water):logP = 2.20; Solubility:In water 735 /l (25 °C). Readily soluble in common organic solvents, e.g. alcohols, acetone, dioxane, xylene, chloroform, diethyl ether.; Stability:Stable in solution, but slowly decomposed in acidic and alkaline media. Very stable in dry, neutral conditions. Degradation is accelerated by light. Decomposes at 220 °C.;
Toxicology
Oral:Acute oral LD50 for rats 1430-2490 /. Percutaneous:Acute percutaneous 50 for rats >2000 /. Inhalation:50 (4 h) for rats >3.39 /l air. ADI:0.0006 / [1995].
Environmental Profile
Ecotoxicology: 
Bees:LD50 (oral) >296.3 mg/g b.w.Birds:Acute oral 50 for bobwhite quail 1260, Japanese quail >1690, mallard ducks >500 /.Daphnia:LD50 (48 h) 32.5 /l.Fish:LD50(96 h) for carp 74, rainbow trout 56-75 /l.Worms:LD50 (14 d) for Eisenia foetida >1000 /.Other beneficial spp.:Harmless to beneficials. 

Environmental fate: 
Soil:In soil, breakdown involves cleavage of the methyl and methoxy groups on the terminal nitrogen atom, simultaneous ring hydroxylation and formation of 3-(2-hydroxy-4-chlorophenyl)urea and the corresponding 3-hydroxy compound. Further degradation presumablyPlant:Degradation in plants is similar to that in soil.
Transport Information
Signal Word:CAUTION; Hazard Class:III(Slightly hazardous)
