N′-(Butan-2-ylidene)furan-2-carbohydrazide

The title Schiff base compound, C9H12N2O2, was obtained from a condensation reaction of butan-2-one and furan-2-carbohydrazide. The furan ring and the hydrazide fragment are roughly planar, the largest deviation from the mean plane being 0.069 (2)Å, but the butanylidene group is twisted slightly with respect to this plane by a dihedral angle of 5.2 (3)°. In the crystal, intermolecular N—H...O hydrogen bonds link pairs of inversion-related molecules, forming dimers of R22(8) graph-set motif.
