Abstract: The title carbohydrate, C13H22O6, is a derivative of D-glycose, in which the furanosidic and isopropylidene rings are in twisted conformations. The mean plane of the furanosidic ring makes a dihedral angle of 70.32 (18)° with the mean plane of the fused isopropylidene ring. The methyl groups in the other isopropylidene ring are disordered over two sets of sites, with an occupancy ratio of 0.74 (6):0.26 (6). In the crystal, molecules are linked by O-H...O hydrogen bonds into chains with graph-set notation C(5) along [100]. Weak C-H...O interactions also occur.
