In the title compound, C12H13NO3S, a saccharin derivative, the dihedral angle between the aromatic and isothiazole rings is 2.91 (12)°. The planar 3,3-dimethylallyl group [maximum deviation = 0.0086 (16) Å] is oriented at dihedral angles of 71.86 (7) and 74.35 (7)° with respect to the aromatic and isothiazole rings, respectively. In the crystal structure, weak intermolecular C—H⋯O interactions link the molecules into chains along the c axis. A weak C—H⋯π interaction is also present.
