摘要：

Information about the presence and the nature of various deprotonated forms of malonic acid in lyophilizates prepared from parent solutions at different pH values can be obtained by solid-state, natural abundance 13C NMR spectroscopy, particularly if a 13C-enriched substrate is used (see picture). pK values calculated from solid-state acid:base ratios are found to be equal to those classically measured in the liquid state.
