Chemical Information
FooDB Name2-Methylhexanoic acid
Description2-Methylhexanoic acid, also known as alpha -methylcaproic acid or 2-methylhexanoate, belongs to the class of organic compounds known as medium-chain fatty acids. These are fatty acids with an aliphatic tail that contains between 4 and 12 carbon atoms. 2-Methylhexanoic acid is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral.
