In the title compound, C(14)H(13)N(3)O(3), the pyrazoline ring assumes an envelope conformation with the furanyl-bearing C atom at the flap position. The dihedral angle between the furan and nitrobenzene rings is 84.40 (9)°. Weak inter-molecular C-H⋯O hydrogen bonding is present in the crystal structure.
