The title Schiff base compound, C11H9N3O3, was obtained from a condensation reaction of furan-2-carbaldehyde and 2-nitrophenylhydrazine. The molecule is roughly planar, the largest deviation from the mean plane defined by all non-H atoms being 0.097 (4). An in ntramolecular N-HO hydrogen bond might influence the planar conformation of the molecule. In the crystal, weak C-HO hydrogen bonds link the molecules, forming a chain.
