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.
