5-Fluoro-4-hydroxy-2-methoxypyrimi dine exists in a solution as two oxo tautomers with the conjugated and isolated double bonds in the ring. The latter tautomer has a zwitterionic structure, and it dominates in water and trifluoroethanol. 5-Fluoro-4-hydroxy-2-methoxypyrimidine in acidic medium gives rise to an equilibrium mixture of two protonated forms at a ratio of about similar to 1:1. The zwitterionic structure of 4-hydroxypyrimidines is stabilized if the solvent is capable for specific solvation via hydrogen bonding.
