4-(2,3,4,6-Tetra- O -acetyl-- D -galactopyranosyl)thiosemicarbazide

In the title compound, C15H23N3O9S, the hexopyranosyl ring adopts a chair conformation. The acetyl group at C4 occupies an axial position, while all other substituents are equatorial. The mol­ecules are linked by C—H⋯O hydrogen bonds into ribbons parallel to the a axis, and N—H⋯O inter­actions provide further stability in a three-dimensional network.
