title: 5-Pentyl-4-phenyl-sulfonyl-1H-pyrazol-3-ol.
abstract: In the title compound, C(14)H(18)N(2)O(3)S, the 1H-pyrazole ring is approximately planar, with a maximum deviation of 0.005 (1) Å. The dihedral angle formed between the 1H-pyrazole and phenyl rings is 79.09 (5)°. Pairs of inter-molecular N-H⋯O and O⋯H⋯N hydrogen bonds form dimers between neighboring mol-ecules, generating R(2) (2)(10) ring motifs. These dimers are further linked by intermolecular N-H⋯O and O-H⋯N hydrogen bonds into two-dimensional arrays parallel to the ac plane. The crystal structure is also stabilized by C-H⋯π inter-actions.
