Abstract: The title compound, C6H12O6, a C-3 position epimer of D-galactose, crystallized from an aqueous solution, was confirmed as [beta]-D-pyran­ose with a 4C1 (C1) conformation. In the crystal, O-H...O hydrogen bonds between the hy­droxy groups at the C-1 and C-6 positions connect mol­ecules into a tape structure with an R33(11) ring motif running along the a-axis direction. The tapes are connected by further O-H...O hydrogen bonds, forming a three-dimensional network.
