Physical & Safety Data

Physical Properties

Molecular weight:332.1; Physical form:Colourless, almost odourless solid. Density:1.441 (20 °C); Melting point:112.6 °C; Vapour pressure:0.013 mPa (25 °C, gas saturation method); Henry constant:2.29×10-3 Pa m3 mol-1 (25 °C, calc.); Partition coefficient(n-octanol and water):logP = 3.15 (22 °C); Solubility:In water c. 2 ppm (25 °C). In acetone, ethyl acetate and 1,2-dichloroethane >250, ethanol c. 13, n-heptane c. 2, xylene c. 60 (all in g/kg, 22 °C).; Stability:Stable to 250 °C (under nitrogen). Stable to light. In solution, hydrolysis occurs at pH 5-9.

Toxicology

Oral:Acute oral LD₅₀ for rats >4500 mg/kg, mice >10,000 mg/kg. Percutaneous:Acute percutaneous LD₅₀ for rats >5000 mg/kg. Non-irritating to skin and eyes (rabbits). Not a skin sensitiser (guinea pigs). Inhalation:LC₅₀ (4 h) for rats >10 mg/l air.

Environmental Profile

Ecotoxicology: Algae:EC₅₀ (96 h) for Selenastrum capricornutum 30 mg/l.Bees:LD₅₀ (oral) >100 mg/bee.Birds:Acute oral LD₅₀ for quail and mallard ducks >4500 mg/kg.Daphnia:LC₅₀ (48 h) 1.18 mg/l.Fish: LC₅₀ (96 h) for trout 27.5 mg/l.Other beneficial spp.:Harmless to Phytoseiulus persimilis at up to 2 recommended application rate. Environmental fate: Animals:Chlozolinate is readily absorbed, metabolised and excreted. Metabolites identified in urine of rats are: 3-(3,5-dichlorophenyl)-5-methyloxazolidin-2,4-dione, N-(3,5-dichlorophenyl)-2-hydroxypropionamide, O-1-carboxyethyl-N-3,5-dSoil:In silt-loam, sandy loam and clay loam soils, hydrolysis and decarboxylation occur; aerobic DT₅₀ <7 h.Plant:In plants, chlozolinate undergoes hydrolysis and decarboxylation processes, giving the same metabolites as those identified in animals.
