In the title compound, C22H27N3O9S, the six-membered pyranosyl ring adopts a chair conformation. The acetyl group opposite the thiosemicarbazone substituent occupies an axial position, while all other substituents are in equatorial positions. The molecules are linked by C—HO hydrogen bonds into chains parallel to the b axis, and two additional C—HO interactions provide further stability in a three-dimensional network.
