Chemische Eigenschaften
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.
Verwenden
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.
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.
synthetische
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
Allgemeine Beschreibung
Radiofrequency-induced plasmas of methyl isobutyrate has been studied using mass spectrometry.
Carcinogenicity
Not listed by ACGIH, California Proposition 65, IARC, NTP, or OSHA.
