Product Description
Ethyl Acetoacetate is an important raw material and versatile intermediate widely used in organic synthesis and chemical manufacturing. In the agrochemical industry, it serves as a key precursor for the preparation of various pesticide intermediates, including α-chloroethyl acetoacetate, which is used in the synthesis of the organophosphorus insecticide coumaphos, and 2-methoxy-4-methyl-6-hydroxypyrimidine, an intermediate for pyrimidinoxam. It is also utilized in the manufacture of insecticides such as diazinon and pirimicarb, as well as fungicidal compounds including oxazolidinones.
