Abstract
This research was undertaken to synthesizes and evaluate 3,5-dihydroxymethyl-4-(2-fluorophenyl)-2,6-dimethylpyridine and 4-(fluoromethyl)-2,6-dimethylpyridine as indicators of 19 F NMR pH. A comparison of 3,5-dihydroxymethyl-4-(2-fluorophenyl)-2,6-dimethylpyridine to 4-(fluoromethyl)-2,6-dimethylpyridine showed that 4-(fluoromethyl)-2,6-dimethylpyridine has a large 19 F chemical shift to pH, a suitable pKa value and a good water solubility.
