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.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

General References:
- Under the conditions of the classical acetoacetic ester route to methyl ketones [see, e.g.: Org. Synth. Coll., 1, 248, 351 (1941)], varying amounts of O-alkylation occur. Regioselective C-alkylation can be obtained by phase-transfer procedures: J. Org. Chem., 39, 3271 (1974). For improved alkylation using TBAB, see: Org. Prep. Proced. Int., 26, 469 (1994).
- Many techniques have been devised for the decarboalkoxylation of substituted ß-ketoesters (compare Diethyl malonate, A15468); for reviews, see: Synthesis, 805, 893 (1982). Enolisable ß-keto esters can be decarboalkoxylated by heating in toluene in the presence of a catalytic amount of DMAP. Other bases are ineffective: J. Org. Chem., 54, 3474 (1989).
