The asymmetric unit of the title compound, C12H11NO4, contains two molecules. In the crystal, neighbouring molecules are linked together by O-H...O hydrogen bonds into dimers. The dimers are arranged into columns parallel to the a axis, meditated by π- π interactions [centroid-centroid distances = 3.856 (3) and 3.857 (3) A]. The crystal structure is further stabilized by weak intermolecular C-H...O interactions. The crystal studied was a non-merohedral twin with a ratio of the twin components of 0.657 (11):0.343 (11).
