| 2-Methyl-2-pentenoic acid Usage And Synthesis |
Description | May be prepared by distillation of 2-hydroxy-2-methylvaleric acid
(m-form). | Chemical Properties | With a
dry acid note, 2-Methyl-2-pentenoic Acid is found in the odor of strawberries.The acid can be prepared from the
corresponding saturated one by α-bromination followed by dehydrobromination.
It is used in fragrances to enhance fruity notes and in strawberry flavors. | Chemical Properties | white semi-transparent crystalline | Chemical Properties | 2-Methyl-2-pentenoic acid has a fruity odor. | Occurrence | Reported found in strawberry | Uses | 2-Methyl-2-pentenoic Acid (CAS# 3142-72-1) can be used for cleansing and refreshing hair and scalp. It can also be used to store and cure food products, and for providing a long-lasting strawberry odor. | 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. |
