In the mol-ecule of the title compound, C(23)H(18)BrN(3)O(3), the benzotriazole mean plane makes dihedral angles of 1.26 (1) and 87.39 (1)° with the tolyl and bromophenyl benzene rings, respectively, and the dihedral angle between the benzene rings is 87.27 (1)°. In the crystal structure, mol-ecules are linked into chains along the a axis by C-H⋯O inter-molecular hydrogen bonds. The structure is further stabilized by C-H⋯π and π-π inter-actions, with a distance of 3.700 (1) Å between the centroids of the bromophenyl and benzotriazole benzene rings related by symmetry code (x, -1 + y, z).
