In the title compound, C10H7BrF3N3O, the dihedral angle between the benzene and triazole rings is 23.17 (12)° and the C atom of the -CF3 group deviates from its attached ring plane by 1.147 (3) Å. In the crystal, mol-ecules are linked by C-H⋯N inter-actions, generating C(7) chains running along [010].
