trans-2-Methyl-2-pentenoic acid Chemical Properties,Uses,Production
Chemical Properties
2-Methyl-2-pentenoic acid has a fruity odor.
Chemical Properties
clear colorless to pale yellow liquid
Occurrence
Reported found in strawberry
Uses
trans-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.
Definition
ChEBI: 2-Methyl-2-pentenoic acid is a methyl-branched fatty acid. It is a conjugate acid of a 2-methyl-(2E)-pentenoate(1-).
Preparation
By distillation of 2-hydroxy-2-methylvaleric acid (cis-form).
Taste threshold values
Taste characteristics at 50 ppm: sour, acidic, sweaty, berry and fruit-like.
General Description
Adsorption 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.
