In the title compound, C(12)H(10)N(2)O(3), the dihedral angle between the benzene ring and the furan ring is 16.12 (13)°. The conformation is stabilized by an intra-molecular O-H⋯N hydrogen bond. Inter-molecular N-H⋯O hydrogen bonds with the keto group as acceptor lead to strands along [001]. The mol-ecule displays a trans configuration with respect to the C=N and N-N bonds.
