Isobutyl acetoacetate Chemical Properties,Usage,Production
Description
Isobutyl acetoacetate has a sweet, winey, brandy-like odor and a sweet and slightly fruity flavor. May be prepared from isobutyl acetate by heating in the presence of sodium isobutylate.
Chemical Properties
Isobutyl acetoacetate has a sweet, winy, brandy-like odor and a sweet and slightly fruity flavor.
Chemical Properties
Isobutyl acetoacetate is a clear colorless liquid. Insoluble in water, soluble in alcohol and oils. B.P. approximately 196℃. The odor is somewhat fresher, not as "fermented" as that of the n-But yiester, while the taste of the iso-Butylester is somewhat less sweet. In general, the former is preferred for “winey” effects, while this (latter) is preferred for fruity effects, and partly as a fixative for the more volatile esters used in hard candy flavoring etc. Concentrations are usually around 25 ppm.
Uses
Isobutyl acetoacetate is used as intermediate for the production of pharmaceuticals (e.g. Nisoldipine). Product Data Sheet
Uses
Isobutyl Acetoacetate is a building block that has been used as a reactant in the preparation of b-annulated 1,4-dihydropyridine derivatives as TGFβ signaling inhibitors.
Definition
ChEBI: 2-Methylpropyl 3-oxobutanoate is an oxo carboxylic acid.
Preparation
From isobutyl acetate by heating in the presence of sodium isobutylate. Or by Claisen condensation of iso-ButyI acetate with Ethylacetate, using Sodium ethoxide catalyst.
