Application
Methyl acetoacetate was used in development of a simple and cost effective method for monitoring of trace formaldehyde in air. It was used to study the substrate specificity of NADPH-dependent diacetyl reductase in Escherichia coli.
General description
Methyl acetoacetate undergoes asymmetric hydrogenation to form (R)-(-)-methyl-3-hydroxybutyrate in the presence of enantioselective Ni/SiO2 catalysts. It undergoes Pechmann reactions with phenols in various ionic liquids.

A reduced nicotinamide adenine dinucleotide phosphate (NADPH)-dependent reductase with the ability to reduce diacetyl has been isolated from Escherichia coli and has been purified 800-fold to near homogeneity. The product of the reduction of diacetyl was shown to be acetoin.
