Abstract: The title compound, C8H15NO7, the methyl carbamate of [beta]-D-glucosamine has been synthesized, in moderate yield, from the reaction of [beta]-D-glucosamine hydrochloride and methyl chloroformate. There are two crystallographically independent molecules in the asymmetric unit. In both molecules, the pyranose ring adopts a slightly distorted chair conformation. In the crystal structure, molecules are packed along the a axis, with intra- and intermolecular O-H...O, N-H...O and C-H...O hydrogen bonds.
