There are two independent 3,5-dimethylpyrazole and two independent 2-hydroxy-5-(phenyldiazenyl)benzoic acid molecules [in which intramolecular O-H center dot center dot center dot O bonds form S(6) graph-set motifs] in the asymmetric unit of the title compound, C(5)H(8)N(2)center dot C(13)H(10)N(2)O(3). In the crystal, the components are linked by intermolecular O-H center dot center dot center dot O, O-H center dot center dot center dot N and N-H center dot center dot center dot O hydrogen bonds, forming four-component clusters. Further stabilization is provided by weak C-H center dot center dot center dot pi interactions.
