In the title 1:1 adduct, C(6)H(12)N(2)O(2)·C(9)H(10)N(2)O(2), the maximum deviations from the 1H-pyrazole-5-ol and furan rings are 0.014 (1) and 0.003 (1) Å, respectively. The dihedral angle formed between the 1H-pyrazol-5-ol and 2,5-dimethyl-furan rings is 21.07 (5)°. In the crystal, pairs of inter-molecular O-H⋯N hydrogen bonds form inversion dimers of the 3-(2,5-dimethyl-furan-3-yl)-1H-pyrazol-5-ol species, generating R(2) (2)(8) ring motifs. Mol-ecules are further linked by inter-molecular N-H⋯O, N-H⋯N and C-H⋯O hydrogen bonds to form ribbons along the [010] direction containing bifurcated R(1) (2)(5) and R(2) (1)(7) ring motifs. Further stablization of the packing is provided by weak π-π [centroid-centroid distance = 3.5686 (15) Å] and C-H⋯π inter-actions.
