In the title compound, C12H11N3O2, the benzotriazole ring system is approximately planar [maximum deviation = 0.008 (1) Å] and its mean plane is oriented at a dihedral angle of 24.05 (4)° with respect to the furan ring. In the crystal, O—H
N hydrogen bonds link the molecules into chains along the ac diagonal. π–π stacking between the furan rings, between the triazole and benzene rings, and between the benzene rings [centroid–centroid distances = 3.724 (1), 3.786 (1) and 3.8623 (9) Å] are also observed.

In the title compound, C19H15Cl2N3O2, the benzotriazole ring system is approximately planar [maximum deviation = 0.018 (2) Å] and its mean plane is oriented at dihedral angles of 30.70 (5) and 87.38 (4)°, respectively, to the furan and benzene rings while the dihedral angle between furan and benzene rings is 74.46 (6)°. In the crystal, weak C—HN hydrogen bonds link the molecules into chains along the b axis. π–π stacking interactions between the parallel dichlorobenzene rings of adjacent molecules [centroid–centroid distance = 3.6847 (9) Å] and weak C—Hπ interactions are also observed.
