水胺硫磷(Optunul,Bay 93820)系1975年华中师范学院研制的新有机磷杀虫剂。1979年我省胶县农药厂试产。其化学名称是0—甲基—0—(邻—异丙氧基羰基苯基)硫代磷酰胺。据测定。对大白鼠口服急性致死中量为28.5毫克/公斤体重,涂皮急性致死中量为447.1毫克/公斤体重,说明水胺硫磷口服毒性虽高,但经皮毒性低。主要
Hydrochlorothiazide (Optunul, Bay 93820) is a new organophosphate pesticide developed by the Central China Normal University in 1975. In 1979 I County plastic pesticide plant trial production. Its chemical name is O-methyl-O- (o-isopropoxycarbonylphenyl) thiophosphoramide. According to determination. Oral acute lethal dose in rats was 28.5 mg / kg body weight, the amount of acute lethality in the coating was 447.1 mg / kg body weight, indicating that oral toxicity of methamidophos is high, but its percutaneous toxicity is low. main
