It is an oxidized derivative of imidazolidine.In a more general sense, hydantoins can refer to a groups and a class of compounds with the same ring structure as the parent. For example, phenytoin (mentioned below) has two phenyl groups substituted onto the number 5 carbon in a hydantoin molecule.t is an oxidized derivative of imidazolidine.
