Methyl isobutyrate Usage And Synthesis

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.

Uses

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).

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.

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.

Taste threshold values

Taste characteristics at 35 ppm: sweet, ethereal, fruity and juicy fruit

General Description

Radiofrequency-induced plasmas of methyl isobutyrate has been studied using mass spectrometry.

Carcinogenicity

Not listed by ACGIH, California Proposition 65, IARC, NTP, or OSHA.
