| Physical and Chemical Properties | The pure chemical product is white solid, odorless and bitter. m.p.198 ℃; The original drug is gray-white crystalline powder with an active ingredient content of more than 95%, m.p.187 ℃. Soluble in boiling alcohol, insoluble in water (0.06g/100mL). The chemical properties are stable, not easy to deteriorate, and the grinding will not fail after being damp and caking. |
| Use | Use thiourea acute rodenticide. Strong selectivity, mainly used for the prevention and treatment of rodents and yellow rats, low toxicity to other mice. The drug has a strong gastric toxicity, can also damage the respiratory system of rodents. General food within 6 to 72h after death. The first time to use the effect is ideal, but the intake of sub-lethal dose will produce strong drug resistance, resistance ability can be increased by 7~50 times, and the other thiourea derivatives produce cross resistance. |
