| Common Name | 3-Methylpentanoic acid |
|---|
| Description | 3-Methylpentanoic acid, also known as 3-methyl-pentanoate or 3-methyl-N-valeric acid, 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 3-Methylpentanoic acid. |
