Deskripsi
The crystal structure of the title water-soluble analogue of vitamin E, trolox amide, C14H19NO3, 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.
