Molecular formula : MW : CAS :
nature : also known as Su-urea on the 1st. Names o-benzoyl-3-(4-chlorophenyl) urea on the 1st. Pure white crystals, 199-200 ° C melting point, the packing density of 0.74; Industrial solid green light, the temperature of 190-196 ° C. Do not dissolve in water, ethanol, toluene and chlorobenzene, in acetone solubility of a gram / 100 ml, and the DMSO-soluble N, N - dimethyl formamide and pyridine and other organic solvents, alkaline and encountered strong acid decomposition easy, room temperature storage stability. Is low-toxicity insecticides. In vivo accumulation no obvious toxicity, and no mutagenic, teratogenic effect. Diflubenzuron is an insect chitin synthesis inhibitor. With high and low toxicity, long Vinca, pollution of the environment has the advantage of integrated control harmful organisms fine varieties. Armyworm of wheat, 430072, Pieris rapae, jujube geometrid, Hyphantria cunea, mosquitoes and other pests have such good control. Neighbors from benzoyl chloride and chlorine 102600 Urea catalyst role in the Synthesis. Processing% 25% and 50% of the SC.
