Abstract: The molecule of the title compound, C12H14N4O, is roughly planar, with a dihedral angle of 8.0 (8)° between the benzene and pyrazole rings, and an intramolecular N-HO hydrogen bond forms an S(6) ring motif. In the crystal, molecules are linked into an inversion dimer by a pair of N-HO hydrogen bonds, which form an R22(8) ring motif.
