Meperfluthrin is light gray to light brown solid, melting point 72～75℃, vapor pressure 686.2Pa (200℃), specific gravity 12329g/ml, insoluble in water, easily soluble in toluene, chloroform, acetone, dichloromethane , dimethylformamide and other organic solvents. Stable under acidic and neutral conditions, but hydrolyzed faster under alkaline conditions.
Meperfluthrin is a chemical widely used in inhalation and contact insecticides. It has a fairly high knockdown and killing activity against mosquitoes, flies and other sanitary pests.
Renofluthrin is commercially produced through an industrially scalable process that yields a high-purity mixture of specific isomers. The synthesis involves the esterification of 2,3,5,6-tetrafluoro-4-(methoxymethyl)benzyl alcohol with 3-(2,2-dichlorovinyl)-2,2-dimethylcyclopropane carboxylic acid, resulting in a compound with a controlled ratio of trans and cis isomers. The process avoids the need for isolating individual isomers, enhancing efficiency and cost-effectiveness.
