Abstract: In the title compound, C₇H₉ClN₄, the 3-chloro-6-hydrazinylpyridazine unit is planar (r.m.s. deviation = 0.0219 Å) and is oriented at a dihedral angle 4.66 (27)° with respect to the propan-2-ylidene group. In the crystal, the molecules are linked into non-planar dimers due to a crystallographic twofold rotation via N-HN hydrogen bonds with R₂²(8) graph-set ring motifs.
