B. P.: V. P.: 4.25 × 10-3 MPa (25 ° C, gas saturation method) Henry: 0.033 PA m3 mol-1S. G. 
Solubility: In water <0.05 mg/l (25 ° C). Soluble in most organic solvents, e. G. Acetone, dimethylformamide 100, acetophenone, cyclohexanone 50, isophorone 35, xylene 20, cyclohexane, 2-ethoxyethanol, kerosene <10 (all in g/kg, 20 ° C). 
Stability: Stable in air up to melting point. At 22 ° C, very stable in aqueous solution at pH 5, 7 and 9. 
Fairly stable to photolysis. 

Toxicity 
Oral: Acute oral LD50 for rats >2000, mice >1000, rabbits >5000 mg/kg. 
Skin and eye: Acute percutaneous LD50 for rats >2000 mg/kg. 
Non-irritating to skin and eyes (rabbits) 
Inhalation: LC50 (4 h) for rats >2.34 mg/l air. 
Application 
Biochemistry: Carotenoid synthesis (phytoene desaturase) & photosynthetic electron flow inhibitor. Mode of action: Selective contact and residual herbicide, absorbed principally by the shoots of germinating seedlings, with limited translocation. Uses: Applied at 125-250 g/ha pre- or early post-emergence in autumn-sown wheat and barley to control grass and broad-leaved weeds, particularly Galium, Veronica and Viola spp. Normally used in combination with isoproturon or other cereal herbicides. Phytotoxicity: Any slight phytotoxicity is in the form of small transient patches on basal leaves, with no adverse effect on crop development.
