Metabolite Identification
Common Name2-Ethylhexanoic acid
Description2-Ethylhexanoic acid, also known as 2-ethylhexanoate or alpha-ethylcaproic acid, 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-Ethylhexanoic acid is a very hydrophobic molecule, practically insoluble in water, and relatively neutral. 2-Ethylhexanoic acid is a potentially toxic compound.
