4-diamino-6-piperidinylpyrimidine 3-oxide and 2,4-diamino-6-(diallylamino)triazine 3-oxide) react with sources of sulfur trioxide, such as sulfur trioxide trimethylamine or chlorosulfuryl chloride, to yield the corresponding heterocyclic O-sulfates. These sulfates are inner salts with unusual physical properties. The structure of the O-sulfate of 2,4-diamino-6-piperidinylpyrimidine 3-oxide was confirmed by X-ray
