In the molecule of the title compound, C11H11NO4S, the isoindoline ring system is almost planar with a maximum deviation of 0.008 (3)Å. In the crystal structure, intermolecular C—H⋯O interactions link the molecules 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.
