Vapor pressure 1.9×10-4mPa(25℃).KowIgP=1.64(25℃),Solubility in water(pH 4.5,20℃)77.63g/L;Solubility in other solvents(20℃,g/L):n-hexane77.63,1,2-dichloroethane,methanol,acetone,m-xylene,ethyl acetate≥1000.Photolysis of aqueous solution DT50 ( 25℃):179d(pH 4),178d(pH 7),8d(pH 9). | | Production Methods | Imicyafos is typically synthesised through a multi-step process involving the formation of a phosphonothioate ester. The key reaction includes the condensation of O-ethyl and S-propyl groups with a substituted imidazolidine ring bearing a cyanoimino moiety. This synthesis requires precise control of reaction conditions to ensure the correct (E)-configuration of the final molecule. | | Definition | ChEBI: Imicyafos is a member of imidazolidines. | | Mechanism of action | High contact activity with and fast diffusion in soil. Acetylcholinesterase (AChE) inhibitor. | | Pesticide Type | Nematicide |
