In the title compound, C12H10N2O4, the furan-2-ylmethyl group is disordered over two sets of sites, with refined occupancies of 0.858 (3) and 0.143 (3). In the major component of disorder, the dihedral angle between the furan and benzene rings is 63.1 (2) and for the minor component this value is 67.9 (6) . The planes of the nitro group and the attached benzene ring form a dihedral angle of 4.34 (17) . In the crystal, inversion-related molecules are linked by two pairs of weak C—H O interactions, one involving the nitro group and the other involving the O—H group as an acceptor. As a result of these associations, ribbons are formed along . A strong intramolecular O—H N hydrogen bond is observed.
