Chemical Information
FooDB Name2-Methylbutanoic acid
DescriptionEthylmethylacetic acid, also known as alpha-methyl butyric acid or a-methyl butyrate, 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 small amount of articles have been published on Ethylmethylacetic acid.
