Vapour pressure:4.9 mPa (25℃); Henry constant:2.09 × 10-3 Pa m3 mol-1 (calc.); Partition coefficient(n-octanol and water):logP = 2.45 (24℃); Solubility:In distilled water 0.05% (25℃). In methanol, toluene >800, ethyl acetate >900, hexane 64 (all in g/l).; Stability:Stable to light.

Toxicology

Oral:Acute oral LD₅₀ for rats 1470 mg/ kg. Percutaneous:Acute percutaneous LD₅₀ for rabbits 4.22 ml/ kg; not a primary irritant to them. Inhalation: LC₅₀ (4 h) for rats 0.58 mg/l.

Environmental Profile

Ecotoxicology:?
Birds: LD₅₀ for bobwhite quail 346, mallard ducks >887 mg/kg. Dietary LC₅₀ (8 d) for bobwhite quail and mallard ducks >5620 ppm.Daphnia: LC₅₀ (48 h) 0.180 mg/l.Fish: LC₅₀ (96 h) for bluegill sunfish 0.196, fathead minnow 0.140, rainbow trout 0.065, channel catfish 0.177 mg/l.?

Environmental fate:?
Soil:River water die-away tests at an initial concentration of 1 ppm of a.i. showed that 40-100% of the fungicide was destroyed within one month. The a.i. was also strongly adsorbed by clays and soil.
