It is used for treating canine hepatitis. Uses D-Glucurono-6,3-lactone is a glucuronic acid derivative studied for its effectiveness against canine hepatitis. It is utilized in the studies such as starting regent in the synthesis of 2,3,4,-tris(tert.-butyldimethysilyl) glucuronic acid trichloroethylester, required for the preparation of 1-O-acyl glucuronide of the anti-inflammatory drug ML-3000, synthesis of optically active glucopyranoses, synthesis of long-chain alkyl glucofuranosides. Definition The γ-lactone of glucuronic acid. Found in plant gums and animal connective tissues. 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.
