The title compound, C19H16N2O, crystallized with two independent mol-ecules (A and B) in the asymmetric unit. There is an intra-molecular O-H⋯N hydrogen bond in each mol-ecule with the phenol ring being inclined to the central benzene ring by 4.93 (14) and 7.12 (14)° in mol-ecules A and B, respectively. The conformation of the two mol-ecules differs essentially in the orientation of the terminal amino-phenyl ring with respect to the central benzene ring; this dihedral angle is 50.51 (4)° in mol-ecule A and 54.61 (14)° in mol-ecule B. The two outer aromatic rings are inclined to one another by 51.39 (14) and 49.88 (14)° in mol-ecules A and B, respectively. In the crystal, mol-ecules are connected by N-H⋯O hydrogen bonds generating -A-B-A-B- zigzag chains extending along [010]. The chains are linked via C-H⋯π inter-actions involving neighbouring A mol-ecules, forming slabs lying parallel to (100).
