Abstract: In the title compound, C8H9N3O4, there are two molecules in the asymmetric unit, one of which is in the zwitterionic form. The zwitterion contains an intramolecular N-H...O hydrogen bond and the other molecule contains both an intramolecular N-H...O and an intramolecular O-H...O hydrogen bond. In the crystal, N-H...O and N-H...N hydrogen bonds link the molecules, formimg a two-dimensional network parallel to (10-1).
