Methyl acetoacetate Usage And Synthesis
Chemical Properties Colorless, clear liquid
Uses Methyl acetoacetate (MAA) is a starting material for the syntheses of alpha-substituted aceto- acetic esters and cyclic compounds, e.g. pyrazole, pyrimidine and coumarin derivatives.
Uses 3-Oxobutanoic Acid Methyl Ester is a chemical reagent used in the synthesis of pharmaceuticals. It participates in the Biginelli reaction, forming molecules including dihydropyrimidinones.
Production Methods Methyl acetoacetate is produced by a reaction of methyl acetate with sodium methoxide.
General Description A clear colorless liquid. Flash point 158°F. Denser than water and slightly soluble in water. Vapors heavier than air.
Air & Water Reactions Very slightly soluble in water.
