1-Cyclo-hexyl-5-(4-meth-oxy-phen-yl)-1H-pyrazole-4-carb-oxy-lic acid.

In the title compound, C(17)H(20)N(2)O(3), the meth-oxy-phenyl unit is disordered over two sets of sites in a 0.715 (4):0.285 (4) ratio. The pyrazole ring forms dihedral angles of 55.88 (16) and 72.6 (4)° with the benzene rings of its major and minor components, respectively. The cyclo-hexane ring adopts a chair conformation and its C-N bond is in an equatorial orientation. In the crystal, mol-ecules are linked into inversion dimers by pairs of O-H⋯O hydrogen bonds, generating R(2) (2)(8) loops.
