Abstract: In the structure of the title compound, 3-hydroxy-6-methyl-2-[4-(3-trifluoromethylphenyl)piperazin-1-ylmethyl]-4H-pyran-4-one, C₁₈H₁₉F₃N₂O₃, the piperazine ring displays an almost perfect chair conformation, with the substituents at the N atoms lying in equatorial positions. The conformation of the molecule is determined by intra- and intermolecular hydrogen bonds.
