Cymoxanil is an organic compound with molecular formula C7H10N4O3 and relative density of 1.31. Solubility at 25 degree : water 1 g/L, dimethylformamide 1.85 g/L, chloroform 105 g/L, methanol 41 g/L, benzene 2 g/L, hexane <1 g/L. It is prepared by acylation and methylation of ethyl urea. It is stable under normal storage conditions and in neutral or weak acid medium, and loses 50% in soil in 7 days.

 Cymoxanil is a highly effective, low-toxic fungicide that is effective against Peronosporales fungi such as Phytophthora, Peronospora, and Peronospora. It is low toxic to humans and animals.
