The title compound, C 8 H 8 N 2 O 4 , differs in its degree of planarity from the 3-nitro isomer and also in its hydrogen-bonding pattern. Its NH group forms an intra-molecular hydrogen bond to a nitro oxygen atom, and its OH group forms an inter-molecular hydrogen bond to an amide oxygen atom, generating [10] chains in the crystal.
