[Purification Methods]

A likely impurity is fumaric acid. In neutral or alkaline solution it readily undergoes ring closure to the 'anhydride' (see below). Crystallise it from water by adding 1.5 volumes of EtOH. The barium salt is stable at 0-5o if dry. [Westfall Biochem J 77 135 1960, Ratner & Kunkemueller Biochemistry 5 1821 1966.]
