In the mol-ecule of the title compound, C(11)H(11)NO(4)S, the isoindoline ring system is almost planar with a maximum deviation of 0.008 (3)Å. In the crystal structure, inter-molecular C-H⋯O inter-actions link the mol-ecules into a three-dimensional network. π-π contacts between the isoindoline rings [centroid-centroid distances = 3.592 (1) and 3.727 (1) Å] may further stabilize the structure.
