Abstract: In the title compound, C₁₆H₁₅N₃O₂, the planar [maximum deviation 0.156 (2) Å] pyrazoline ring is nearly coplanar with the 3-nitrophenyl group and is approximately perpendicular to the phenyl ring, making dihedral angles of 3.80 (8) and 80.58 (10)°, respectively. Weak intermolecular C-HO hydrogen bonding is present in the crystal structure.
