چکیده
The title compound, C(10)H(11)NO(4), was extracted from a culture broth of Penicillium verruculosum YL-52. The mol-ecular structure is essentially planar, with an r.m.s. deviation of 0.01342 (2) Å for the non-H atoms. In the crystal structure, adjacent mol-ecules are connected into a centrosymmetric dimer through a pair of O-H⋯O hydrogen bonds. The dimers are further extended into a chain by weak C-H⋯O hydrogen bonds.

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-pyraz...
