Physical & Safety Data

Physical Properties

Molecular weight:351.9g/mol; Physical form:Olive-green powder. Density:1.63 (20℃); Melting point:Decomposes above 270℃; Vapour pressure:4.6 ×10-5 mPa (25℃) (EEC A.4); Henry constant:2.31 × 10-4 Pa m3 mol-1 (calc.); Partition coefficient(n-octanol and water):logP = 2.46 (distilled water, 25℃).; Solubility:In water 0.07 mg/l ( pH 7, 25℃). In methanol 116, n-hexane <0.01 (both in mg/l, 25℃).; Stability: DT50 60-96 h ( pH 7.0). Chemically inert. Stable to u.v. light.

Toxicology

Oral:Acute oral LD₅₀ for rats 4700, mice 9000 mg/ kg. Percutaneous:Acute percutaneous LD₅₀ for rats >2000 mg/kg. Non-irritating to skin; irritating to eyes (rabbits). Inhalation: LC₅₀ for rats 150 mg/m³ air. Phytotoxicity:Non-phytotoxic when used as directed. Not to be used on copper-sensitive plants.

Environmental Profile

Ecotoxicology:
Algae: EC₅₀ (5 d) 2.20-15.4μg/l.Bees:Non-toxic to bees.Birds: LD₅₀ (8 d) for bobwhite quail 618, mallard ducks >2000 mg/kg. LC₅₀ (8 d) for bobwhite quail 3428, mallard ducks >2000 mg/ kg.Daphnia: LC₅₀ (48 h) 177μg/l.Fish: LC₅₀ (96 h) for bluegill sunfish 21.6, rainbow trout 8.94μg/l.

Environmental fate:
Animals:In rats, 58-62% is excreted in urine and about 25% eliminated in faeces within 72 h. Metabolites were mainly parent and 8-hydroxyquinoline and a small amount of glucuronide and sulfate conjugates.Soil: DT₅₀ 2 d (20℃, 63% MWC). No tendency to leach (90% remained in the 0-6 cm top soil layer).Plant:The product does not penetrate and is not translocated after foliar application after one week in lettuce and up to four weeks in apple. No metabolites were observed in the surface wash-off.
