5-Amino-1-phenyl-3-trifluoro-methyl-1H-pyrazole-4-carboxylic acid.

ABSTRACT: In the title compound, C(11)H(8)F(3)N(3)O(2), there are two mol-ecules 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 mol-ecules are held together by O-H⋯O hydrogen bonds between the carboxyl groups, forming a centrosymmetric dimer with an R(2) (2)(8) motif. Intra-molecular N-H⋯O inter-actions are also present.
