In the title compound, C(10)H(9)NO(6), the carb-oxy, ethoxy-carbonyl and nitro groups form dihedral angles of 3.8 (1), 4.5 (1) and 164.8 (1)°, respectively, with the mean plane of the benzene ring. In the crystal structure, mol-ecules lying about inversion centers are linked through O-H⋯O hydrogen bonds. C-H⋯O inter-actions are also present.
