Physical and Chemical Properties | Yellow-brown crystalline solid. The melting point is 122-123 ℃, and the vapor pressure is 1.33 × 10-3Pa. Insoluble in water, easily soluble in aromatic hydrocarbons. It is stable to water-bearing acid and alkali, but it will lose its activity under high temperature or sunlight ultraviolet light, and the activity will decrease by 50% at 130 ℃ for 6h. |
Use | As a special acaricide, it is used to control mites on greenhouse roses. |
