Descriptiontrans-2-Octenoic acid, also known as (e)-2-octenoate or trans-a-octenoate, 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. trans-2-Octenoic acid is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral.
