Ethyl acetoacetate EAA (CAS 141-97-9) is colorless clarified liquid with cheerful fruit smell. It is easy soluble in ethanol, ethyl ether, propylene glycol and ethyl acetate, and soluble in water as 1:12. Boiling point: 181ºC, melting point: -45ºC (enol: -80ºC, ketone: -39 ºC), flash point: 84.5ºC. Ethyl acetoacetate 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 aminopyrine, 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.
It is a tautomer at room temperature consisting of approximately 8% enol and 92% keto. It is soluble in water and common organic solvents. It is used as a low color-generating copromoter for unsaturated polyester resins.
