title: Propan-2-yl 2-(1,1,3-trioxo-2,3-dihydro-1λ(6),2-benzothia-zol-2-yl)acetate.
abstract: In the title mol-ecule, C(12)H(13)NO(5)S, the benzisothia-zole ring system is essentially planar (r.m.s. deviation = 0.0169 Å) as is the -C-C(=O)-O-C- sequence of atoms in the vicinity of the acetate group (r.m.s. deviation = 0.0044 Å). The mean plane of these atoms forms a dihedral angle of 88.41 (7)° with the benzisothia-zole ring system. In the crystal, weak C-H⋯O hydrogen bonds involving methyl-ene and methyne H atoms form R(4) (3)(20) graph-set motifs.
