In the title compound, C10H18O5.H2O, the fucopyranoside ring adopts a chair conformation. The crystal packing is stabilized by intermolecular O—H...O and C—H...O hydrogen bonds together with intramolecular O...O [2.2936 (8) A ° ] and intermolecular O...O [2.7140 (8)–2.829 (3) A ° ] short contacts. The molecules are linked together to form an infinite chain along the a axis. This structure has been solved previously but with no R-values [Spiers (1931). Z. Kristallogr. Kristallgeom. Kristallphys. Kristallchem. 78, 101].
