2-(3,4-Dimethyl-anilino)acetohydrazide.

The title compound, C10H15N3O, crystallizes in an infinite two-dimensional polymeric network due to inter­molecular N—H⋯O hydrogen bonding. Intra­molecular N—H⋯N and inter­molecular C—H⋯N inter­actions are also present. The 3,4-dimethyl­phenyl unit is disordered over two sites with an occupancy ratio of 0.677 (5):0.323 (5). The dihedral angle between the benzene rings of the disordered components is 2.6 (6)°.
