Abstract: In the title compound, C₁₀H₁₈O₅·H₂O, the fucopyranoside ring adopts a chair conformation. The crystal packing is stabilized by intermolecular O-HO and C-HO hydrogen bonds together with intramolecular OO [2.2936 (8) Å] and intermolecular OO [2.7140 (8)-2.829 (3) Å] 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].
