Products Description of Ethyl acetoacetate CAS# 141-97-9
Ethyl acetoacetate is an important raw material for organic synthesis. In the production of pesticides, it is used to synthesize the intermediate α-chloroethyl acetoacetate of the organophosphorus insecticide coumaphos, the intermediate 2-methoxy-4-methyl-6-hydroxypyrimidine of pyrimidinoxam, the intermediate 2-isopropyl-4-methyl-6-hydroxypyrimidine of diazinon, the carbamate insecticide pirimicarb, the fungicide oxazolidinone, the herbicide imipenem, the chemical book rodenticide coumarin, warfarin, etc. It is also the intermediate of the new fungicide varieties cyprodinil, difulmetorim, furammetpyr and the plant growth regulator cintofen. In addition, ethyl acetoacetate is also widely used in the pharmaceutical, plastic, dye, fragrance, varnish and additive industries.
