Product Details

Ethyl acetoacetate CAS#141-97-9

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.

Product Application of Ethyl acetoacetate CAS#141-97-9

Ethyl acetoacetate can be used as a potential bio-based diluent for improving the cold flow properties of biodiesel from waste cooking oil[1]. Ethyl acetoacetate reacts with glycosylamines to form ethyl 3-(glycosylamino)crotonate, which is further transformed into ethyl 2-methyl-4-(polyhydroxyalkyl)pyrrole-3-carboxylates under conditions that promote the Amadori rearrangement of glycosylamines. It also reacts with ketohexylamines (D-fructosylamine, L-sorbosylamine) to form ethyl 2-methyl-5-(tetrahydroxybutyl)pyrrole-3-carboxylates[2].
