The molecule of title compound, C13H11N5, is essentially planar (r.m.s. deviation = 0.0440 Å) and an intramolecular C—HN hydrogen bond generates an S(6) motif. In the crystal, molecules are connected into chains by intermolecular N—HN and C—HN hydrogen bonds. In addition, π–π stacking interactions are observed between the pyrazole and pyridazine rings [interplanar distance = 3.6859 (10) Å].
