| Common Name | 2-Phenylbutyric acid |
|---|
| Description | 2-Phenylbutyric acid, also known as alpha-phenylbutyrate or alpha-ethyl-alpha-toluate, belongs to the class of organic compounds known as phenylpropanes. Phenylpropanes are organic compounds containing a phenylpropane moiety. 2-Phenylbutyric acid is slightly soluble (in water) and a weakly acidic compound (based on its pKa). 2-Phenylbutyric acid can be biosynthesized from butyric acid. 2-Phenylbutyric acid is used as an anticholesteremic. |
