The original drug was given to rats with acute oral LD501690mg/kg, rabbits with acute percutaneous LD50 > 5278mg/kg, and rats with acute percutaneous LD50 > 2000mg/kg. It has a stimulating effect on rabbit eyes. Its accumulative coefficient K value is more than 5, which belongs to slightly accumulative pesticides. It has no teratogenic, carcinogenic and mutagenic effects on animals. The three generation of reproduction test and neurotoxicity test showed no abnormalities. Two years feeding test, no action dose rats were 200mg/kg. Rainbow trout LC5038mg/L, quail LD50 > 5000mg/kg, duck LD50 > 10000mg/kg, bee LC5060mg/kg.
Pure product is white crystalline solid. M.p.115-117 C, vapor pressure 2.7 65507 The solubility of chloroform is 3880g/kg, methanol 2650g/kg, dimethylformamide 836g/kg, acetone 790g/kg, benzene 940g/kg, toluene 386g/kg, hexane 3g/kg, water 33g/kg.
