title: 2-(6-Benzoyl-2-oxo-1,3-benzothia-zol-3-yl)acetic acid.
abstract: In the title compound, C(16)H(11)NO(4)S, the nine-membered fused ring is nearly planar, with maximum deviations from the mean plane of -0.022 (1) Å for the N atom and 0.011 (1) Å for the S atom, and makes a dihedral angle of 53.56 (7)° with the phenyl ring. The crystal structure is stabilized by O-H⋯O and C-H⋯O hydrogen-bonding inter-actions.
