The title compound, C9H11NO2, was obtained as an unexpected product in an attempt to synthesize a triazene ligand. The title molecule is almost planar, with the formamide and ethoxy groups oriented at 2.7 (3) and 12.9 (2)°, respectively, with respect to the mean plane of the benzene ring. In the crystal, molecules are linked by intermolecular N—HO hydrogen bonds, forming a chain along the a axis. Weak C—Hπ interactions with an Hπ distance of 2.78 Å reinforce the crystal packing, resulting in a three-dimensional network.
