[Uses]

D-Glucurone is a glucuronic acid derivative. It is used for treating canine hepatitis.
[General Description]

D-(+)-Glucuronic acid γ-lactone (Glucourono-γ-lactone, Glucurone or Glycurone) is a carbohydrate derivative. It converted into L-ascorbic acid in animals and human body. Its molecule contains two five-membered rings. Its crystal structure has been studied.
[Purification Methods]

Dissolve the lactone or mixture of lactone and acid in H2O and concentrate on a steam bath until crystallisation begins. Cool rapidly to room temperature wih stirring. After 2hours the product is filtered off, washed with cold EtOH and dried to m 174-175o and [] D +19.8o (c 5.2, H2O). The amount of free acid can be obtained by titration of an ice-cold aqueous solution with standard alkali. It can be recrystallised from EtOH, EtOH/H2O or MeOH, and the highest recorded m is 180o.
