| Abstract: | Dissociation constants of 5-methoxy-6-methyluracil, 5-methoxy-1,6-dimethyluracil and 5-methoxy-3,6-dimethyluracil in water are determined. Basing on the obtained рKа1 values, the content of anions in aqueous alkaline solution of 5-methoxy-6-methyluracil was calculated. The results were confirmed by the use of model compounds: 5-methoxy-1,6-dimethyluracil and 5-methoxy-3,6-dimethyluracil using the NMR spectroscopy. |
