Abstract: In the title compound, C14H20O5, an inter­mediate in the synthesis of oligosaccharides, the glycosidic [H-C-O-C(H3)] torsion angle [varphi]H is 52.3° and the exo-cyclic [H-C-O-C(H2)] torsion angle [theta]H is -11.7°. The hexa­pyran­ose ring has a chair conformation. In the crystal, mol­ecules are linked by O-H...O hydrogen bonds, forming chains propagating along [010]. Enclosed within the chains are R33(12) ring motifs involving three mol­ecules. The chains are linked via C-H...[pi] inter­actions, forming a three-dimensional network.
