Abstract: The asymmetric unit of the title compound, C₁₈H₂₄O₆·H₂O, contains a 14-membered macrolide molecule and a water molecule. In the crystal structure, intramolecular C-HO and O-HO hydrogen bonds help to stabilize the molecular conformation, while intermolecular O-HO hydrogen bonds link the molecules, forming an infinite network. The absolute configuration was assigned by comparison with related zearalenone compounds, but needs verification.
