352271-52-4 - Uses and synthesis methods

introduction

P> chlorofluoroethrin is a light gray to light brown solid, melting point 72~75 ℃, vapor pressure 686.2Pa (200 ℃), specific gravity 12329 g/ml, insoluble in water, soluble in toluene, chloroform, acetone, dichloromethane, dimethylformamide and other organic solvents. It is stable under acidic and neutral conditions, but hydrolyzes faster under alkaline conditions. It can be stored stably for two years at room temperature.

pyrethroid insecticides

Chloroethrin is a fluorine-containing pyrethroid insecticide. It has high fat solubility and hydrophobicity, and can promote the absorption and transfer speed of the agent in the organism. Therefore, the agent has high efficacy, Low toxicity and fast metabolism. According to the tests of Jiangsu Yangnong Chemical Co., Ltd. and other companies, the basic activity of chloroethrin is more than 15 times that of dextran-rich allenethrin. Compared with the mosquito-repellent incense based on chlorofluoroether, the mosquito-repellent incense based on tetrafluoromethyl ether has a slightly better knock-down activity, and the comprehensive cost-effective tetrafluoromethyl ether has a more competitive advantage.

Toxicity

chlorofluoroethrin is a low-toxic pesticide, acute oral toxicity LD50>500mg/kg in rats, acute transdermal toxicity LD50>5000mg/kg in rats, acute transdermal toxicity LC50 3160mg/m3 in rats, no irritation to rabbit eyes and skin, and weak sensitizer to guinea pig skin.
