| Common Name | (±)-2-Methylpentanoic acid |
|---|
| Description | (±)-2-Methylpentanoic acid, also known as alpha-methylvaleric acid or a-methylvalerate, belongs to the class of organic compounds known as methyl-branched fatty acids. These are fatty acids with an acyl chain that has a methyl branch. Usually, they are saturated and contain only one or more methyl group. However, branches other than methyl may be present. Based on a literature review a significant number of articles have been published on (±)-2-Methylpentanoic acid. |
