In the title compound, C(16)H(12)F(3)N(3)O(2)S·0.47C(2)H(5)OH·0.53CH(3)OH, the quinoline ring system is approximately planar, with a maximum deviation of 0.035 (3) Å, and makes a dihedral angle of 52.67 (9)° with the benzene ring. The F atoms of the -CF(3) group are disordered over two orientations, with refined site occupancies of 0.56 (2) and 0.44 (2). A single solvate site is occupied at random by ethanol or methanol, with refined site occupancies of 0.470 (6) and 0.530 (6), respectively. In the crystal, mol-ecules are linked via N-H⋯O, N-H⋯N, O-H⋯O and C-H⋯O hydrogen bonds, thereby forming sheets lying parallel to (010).
