4,5,6-TRIAMINOPYRIMIDINE Chemical Properties,Uses,Production

Uses

4,5,6-Triaminopyrimidine (pyrimidine-4,5,6-triamine) is a pyrimidine derivative. It can be used in the preparation of 5-pyrimidine-6-yloxypyrazole and pyrazole derivatives, as well as in the preparation of nanofiltration membranes and surface-modified substrates for compounds.

Synthesis

61908-15-4

118-70-7

Step 4: Wetted 4,6-diamino-5-nitrosopyrimidine was loaded into a reaction column. 400 mL of methanol and 4 g of 5% palladium carbon catalyst were added to the autoclave and the reaction was stirred at room temperature in a hydrogen atmosphere. Upon completion of the reaction, methanol was removed by evaporating the filtrate. The resulting 4,5,6-triaminopyrimidine can be used directly in the subsequent reaction steps without further purification in 95% yield.
