In the title compound, C11H8F3N3O2, there are two molecules in the asymmetric unit wherein the phenyl rings make dihedral angles of 65.3 (2) and 85.6 (2)° with the pyrazole rings. In the crystal, pairs of molecules are held together by O—H⋯O hydrogen bonds between the carboxyl groups, forming a centrosymmetric dimer with an R 2 2(8) motif. Intramolecular N—H⋯O interactions are also present.
