Overview: 

Pyrethroid pesticides are a new generation of insecticides developed on the basis of imitating the effective ingredients and chemical structure of natural pyrethroids. With its obvious efficacy, high insecticidal activity, wide use, low residual amount and low toxicity to mammals, it has become an ideal variety to replace highly toxic and highly residual organophosphorus pesticides advocated and promoted by the state. Methyl cardic acid, chemical name 3,3 dimethyl-4-pentenoate methyl ester, pure product is colorless transparent, with a special irritating odor liquid. 

Soluble in ethanol, ethyl acetate, ether and other organic solvents, insoluble in water, is a pungent aroma of organic compounds, is the synthesis of all kinds of permethrin the most important intermediate, including permethrin (DV permethrin), vithrin, permethrin, cypermethrin and a series of dichlorothrin insecticides; Cyfluthrin, deltamethrin, rich D-trans allethrin and so on more than a dozen major varieties. Methyl cardinate accounts for about 60% of the cost of the above types of pesticides, plays a key role in the synthesis of various types of permethrin pesticides, the early 1970s took the lead in the industrial production of British Zeneca company, domestic production in recent years, but most are generic category. 

At the same time, methyl cardic acid is also an important chemical raw material, can be used in general organic synthesis, because the production process of methyl cardic acid uses a large number of irritating chemical raw materials, intermediate products and final products are also irritating gas chemicals, so the production process should pay attention to its impact on human health and ecological environment.
