In the title compound, C22H19N3O4, the dihedral angle between the furan and pyrazole rings is 82.73 (19)° while the dihedral angles between the furan and pyrazole rings and their attached benzene rings are 31.93 (18) and 1.88 (18)°, respectively. In the crystal, inversion dimers linked by pairs of C—H
O hydrogen bonds generate R22(16) loops. In addition, weak C—Hπ and aromatic π–π stacking [minimum centroid–centroid distance = 3.5374 (17) Å] interactions are observed.

The asymmetric unit of the title compound, C11H10N4O3, contains two independent molecules in which the benzene rings make dihedral angles of 38.3 (2) and 87.1 (2)° with respect to the triazole rings. In the crystal, the molecules are linked by C—HO hydrogen bonds, forming chains along [021]. Further, weak C—Oπ [3.865 (5) Å, 83.8 (3)°] and N—Oπ [3.275 (5) and 3.240 (6) Å, 141.8 (4) and 102.8 (3)°] interactions are observed.
