Abstract: The title compound, C₁₀H₁₁NO₄, was extracted from a culture broth of Penicillium verruculosum YL-52. The molecular 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 molecules are connected into a centrosymmetric dimer through a pair of O-HO hydrogen bonds. The dimers are further extended into a chain by weak C-HO hydrogen bonds.
