| toxicity | the original drug has no irritating effect on skin and eyes for acute oral LD50 of 0.25~0.4 mg/kg and acute percutaneous LD500.54 mg/kg in rats. Rainbow trout LC500.0091 mg/L, mallard oral LD501.7 mg/kg. |
| use | second generation anticoagulant. It has the advantages of strong toxicity, good palatability and significant deratization effect. It can prevent domestic rats, wild rats and other types of rodenticide resistant rat species. When using, 0.1% powder can be prepared into 0.005% poison bait. After 19 portions of grain bait are soaked and slightly cooled, 0.1% fluororadione powder is added and fully mixed for use. Prevention and control of domestic mice 1~3 bait points per room, 3~5g per point, if necessary 3~6 days later supplement; For the prevention and control of wild rats, a point is set at 50m2, and 5~10g of poison bait is pushed and released at every point. Fluorine ketone is highly toxic, pay attention to safety when using it. |
| Production method | The preparation of 4-hydroxycoumarin is shown in the preparation method of scutamine. 3-[4-(4-trifluoromethylbenzyloxy) phenyl]-1,2,3, 4-tetrahydro-1-naphthol was prepared by reacting 4-trifluoromethylbromide with naphtholone in DMF at room temperature, and the reaction product was reduced with NaBH4. Synthesis of fluororicone 3-[4-(4-trifluoromethylbenzyloxy) phenyl]-1,2,3, 4-tetrahydro-1-naphthol and 4-hydroxycoumarin In the presence of p-methyl benzene sulfonic acid condensation, fluororicone was prepared. |
