In the title compound, C14H12N4O3, the dihedral angle between the benzene rings is 7.6 (4)°. In the crystal, infinite sheets linked by N-HO and bifurcated N-H(O,N) hydrogen bonds propagate in the (10-1) plane, in which R44(36) loops are apparent. Neighbouring layers may interact by way of very weak - stacking interactions [centroid-centroid distances = 3.9329 (13) and 4.0702 (13) Å].
