methyl acetoacetate usage and synthesis

chemical properties	colorless, clear liquid
usage	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.
usage	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.
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.
reactivity profile	methyl acetoacetate is an ester. esters react with acids to liberate heat along with alcohols and acids. strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. heat is also generated by the interaction of esters with caustic solutions. flammable hydrogen is generated by mixing esters with alkali metals and hydrides
health hazard	may be harmful by inhalation, ingestion, or skin absorption. causes eye irritation. may cause skin irritation.
