Milieu dependence of isomeric composition of D-arabino-hexo-2-ulose in aqueous solution determined by high-resolution NMR spectroscopy.

In this study, high-resolution (1)H NMR spectroscopy (600.03 MHz) and (13)C NMR spectroscopy (150.89 MHz) were used to elucidate the structures of equilibrating d-arabino-hexo-2-ulose (GLUC) (1) isomers in aqueous solution.
