Common NameBut-2-enoic acid
DescriptionBut-2-enoic acid, also known as (2E)-2-butenoate or alpha-crotonic acid, belongs to the class of organic compounds known as straight chain organic acids. These are organic acids with a straight aliphatic chain. But-2-enoic acid is a very hydrophobic molecule, practically insoluble in water, and relatively neutral.
