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. | [Flammability and Explosibility]
