Molecular Structure
Category
Activity
Herbicide
An obsolete pre-emergence herbicide once used for total weed control in non-crop and aquatic situations
Physical Properties
Molecular weight:206.1; Physical form:Off-white solid. Melting point:151-152 °C; Vapour pressure:0.13 mPa (20 °C); Henry constant:2.82×10-5 Pa m3 mol-1 (calc.); Solubility:In water 950 mg/l (21 °C). In aromatic and chlorinated hydrocarbons 50-100 g/kg. Stability:Thermally stable up to 90 °C. Stable in acidic solutions, but is converted to dichlobenil in alkaline solutions.
Toxicology
Oral:Acute oral LD50 for rats 757 mg/kg, mice 500 mg/kg. Percutaneous:Acute percutaneous LD50 for rats >1000 mg/kg.
Environmental Profile
Ecotoxicology: 
Bees:Not toxic to bees.Birds:Acute oral LD50 for chickens 500 mg/kg. Fish:LC50 (24 h) for harlequin fish 41 mg/l. 
Environmental fate: 
Animals:In rats, following oral administration, there is rapid metabolism and 70% elimination in the urine within 24 hours.Soil:In soil, chlorthiamid is converted to dichlobenil, which then gradually undergoes microbial degradation to 2,6-dichlorobenzamide and 2,6-dichlorobenzoic acid. Converted to dichlobenil in soil, DT50 for loss from soil.
Transport Information
Signal Word:CAUTION; Hazard Class:III (Slightly hazardous)
