Title: rac-6-Hydroxy-2,5,7,8-tetramethylchroman-2-carboxamide from synchrotron data

The crystal structure of the title water-soluble analogue of vitamin E, trolox amide, C{sub 14}H{sub 19}NO{sub 3}, solved and refined against synchrotron diffraction data, contains two molecules in the asymmetric unit. In both molecules, the heterocyclic ring is in a half-chair conformation. The crystal packing features a herring-bone pattern generated by N-H...O hydrogen bonds between the hydroxy and amide groups. O-H...O hydrogen bonds also occur.
