| | 4,6-Diaminopyrimidine Usage And Synthesis |
| Chemical Properties | Yellow to light yellow crystal | | Uses | 4,6-Diaminopyrimidine is a compound used for the preparations of pharmaceutical goods. It was shown that organotin polyamines derived from reaction with 4,6-diaminopyrimidines displayed good inhibition of two pancreatic cancer cell lines. | | Synthesis | General procedure for the synthesis of 4,6-diaminopyrimidine from the compound (CAS:40070-06-2): 250 mL of 11.5 mol/L hydrochloric acid solution was added to the 4,6-diamino-2-sulfinic acid pyrimidine filter cake obtained in step 2, and the mixture was cooled to -5 °C and stirred continuously for 0.5 h. The mixture was then purified to -5 °C and stirred continuously for 0.5 h. The mixture was purified to -5 °C and stirred continuously for 0.5 h. The mixture was purified to -5 °C and stirred continuously for 0.5 h. The yield of this step was 100%. | | References | [1] Patent: CN103709164, 2016, B.
