In the title compound, C(9)H(7)NO(6), the dihedral angles between the benzene ring and its three substituents are 29.99 (8)° for the nitro, 67.09 (8)° for the carb-oxy and 32.48 (10)° for the meth-oxy-carbonyl group. In the crystal, one classical O-H⋯O and two nonclassical C-H⋯O contacts link adjacent mol-ecules, forming a three-dimensional structure.
