What is Methyl isobutyrate?

Chemical properties

methyl isobutyrate is a clear colourless liquid that has a fruity (apple–pineapple) odor and a sweet flavor reminiscent of apricot. soluble in water, miscible in common organic solvents. flammable. natural products exist in strawberries etc.

Occurrence

Reported found in Russian champagnes and among the volatile components of strawberry juice. Also reported found in apple juice, banana, kumquat peel oil, blueberry, melon, papaya, pineapple, strawberry, fried potato, starfruit, dill herb, cherimoya, kiwifruit, loquat, naranjilla fruit and cape gooseberry.

The Uses of Methyl isobutyrate

Methyl isobutyrate is used as a flavoring agent. It was used as diluent in forced Rayleigh scattering studies to measure diffusion coefficients for a ternary system comprising camphorquinone in poly(methyl methacrylate).

Definition

ChEBI: Methyl isobutyrate is the fatty acid methyl ester of isobutyric acid. It has a role as a metabolite. It derives from an isobutyric acid.

Preparation

Methyl isobutyrate can be synthesized by direct esterification of methanol with isobutyric acid.

What are the applications of Application

Methyl isobutyrate can be used as a solvent, organic synthesis, standard for gas chromatography. radiofrequency-induced plasmas of methyl isobutyrate has been studied using mass spectrometry.
