Molecular weight:200.0; Physical form:Colourless to pale yellow-brown solid. Melting point:130 °C; Vapour pressure:1.68 mPa (20 °C); Solubility:In water 250 g/l (22 °C). In ethanol 500, isopropanol 250, propylene glycol 143, glycerol 10, liquid paraffin <5 (all in g/l, 23-24 °C). Readily soluble in acetone and ethyl acetate; slightly soluble in chloroform, diethyl ether, and benzene; insoluble in; Stability:Slightly hygroscopic. Stable under normal storage conditions, but unstable in aluminium containers.;

Oral:Acute oral LD₅₀ for rats 180-400, mice 250-500, dogs 250 mg/kg. Percutaneous:Acute percutaneous LD₅₀ for rats >1600 mg/kg. Moderate skin irritant; mild eye irritant (rabbits). Inhalation:LC₅₀ (6 h) for rats >5 mg/l air. Phytotoxicity:Non-phytotoxic to a wide range of crops, including cotton.

Ecotoxicology: 
Birds:Acute oral LD₅₀ for mallard ducks 510 mg/kg.Daphnia: LC₅₀(48 h) 1.4 mg/l.Fish: LC₅₀ (96 h) for trout 20.0 mg/l. 

Environmental fate: 
Animals:Oral doses are rapidly absorbed and rapidly excreted, mainly in the urine. The major metabolite has been identified as 2-nitropropane-1,3-diol.Plant:Following treatment of potatoes at a rate of 12 g bronopol/tonne, the residues fell to <0.1 mg/kg after 6 months storage. Biochemical degradation in the tuber leads to the metabolite 2-nitropropan-1,3-diol (Link

Signal Word:WARNING; Hazard Class:II(Moderately hazardous)
