Description and Uses
The organic compound ethyl acetoacetate (EAA) is the ethyl ester of acetoacetic acid. It is mainly used as a chemical intermediate in the production of a wide variety of compounds, such as amino acids, analgesics, antibiotics, antimalarial agents, antipyrine and amino pyrine, and vitamin B1; as well as the manufacture of dyes, inks, lacquers, perfumes, plastics, and yellow paint pigments. Alone, it is used as a flavoring for food.
Ethyl acetoacetate is used as an intermediate in organic synthesis and as a co-promoter for unsaturated polyester resins. It is widely used in the production of dyes, inks, perfumes, plastics and flavoring agents. It is an important starting material for the syntheses of alpha-substituted acetoacetic esters and cyclic compounds like pyrazole, pyrimidine and coumarin derivatives. It acts as an intermediate in the synthesis of vitamins and pharmaceuticals. It finds application as a formaldehyde scavenger.
