The single-crystal structure of 2-S-(6′-deoxy-1′,2′:3′,4′-di-O-isopropylidene-a-D-galacto pyranos-6′-ylthio)-3-methylquinoxaline (C21H26N2O5S) was determined at 293 K and refined to R = 0.0373 for 3634 observed reflections. This crystal is orthorhombic, P212121 with Z = 4. The unit-cell dimensions are: a = 11.0592(9)Å, b = 11.3500(7)Å, c = 16.9656(10)Å and V = 2129.6(3)Å3. Molecules are stacked with C-H***N hydrogen bonds.
