trans-2-Methyl-2-pentenoic acid Usage And Synthesis
Chemical Properties2-Methyl-2-pentenoic acid has a fruity odor.
Chemical Propertiesclear colorless to pale yellow liquid
OccurrenceReported found in strawberry
Usestrans-2-Methyl-2-pentenoic Acid is an unsaturated analog of the anticonvulsant Valproic Acid (V094750) and is used for aroma characterization of different beers with different hops.
DefinitionChEBI: 2-Methyl-2-pentenoic acid is a methyl-branched fatty acid. It is a conjugate acid of a 2-methyl-(2E)-pentenoate(1-).
PreparationBy distillation of 2-hydroxy-2-methylvaleric acid (cis-form).
Taste threshold valuesTaste characteristics at 50 ppm: sour, acidic, sweaty, berry and fruit-like.
General DescriptionAdsorption and desorption of trans-2-methyl-2-pentenoic acid in dichloromethane has been investigated by using in situ attenuated total reflection infrared spectroscopy. Asymmetric hydrogenation of trans-2-methyl-2-pentenoic acid in hexane over two well defined E-40692 and E-5220 Engelhard Pd/Al2O3 catalysts modified with cinchonidine has been studied.
Flammability and ExplosibilityNot classified
