The title compound, C11H6ClN5O4S, crystallized with two independent mol­ecules in the asymmetric unit. The benzene ring makes dihedral angles of 66.46 (8) and 85.77 (9)° with the mean plane of the purine ring in the two mol­ecules. In the crystal, inter­molecular π–π stacking inter­actions [centroid–centroid distance = 3.8968 (12) Å], C—Cl⋯π inter­actions [Cl⋯centroid = 3.2505 (10) Å, C—Cl⋯centroid = 161.56 (18)°] and non-classical C—H⋯O and C—H⋯N hydrogen bonds link the molecules
