摘要：

The asymmetric unit of the title compound, C5H4F6O3, a polyfluorinated derivative of beta-hydroxybutyric acid, comprises two molecules. Intramolecular O-H center dot center dot center dot O hydrogen bonds occur. In the crystal, intermolecular O-H center dot center dot center dot O hydrogen bonds give rise to the formation of carboxylic acid dimers. Along with these hydrogen bonds, C-H center dot center dot center dot O contacts connect the molecules into infinite strands along the a axis.
