Related Products of 3112-31-0,Some common heterocyclic compound, 3112-31-0, name is 1H-Pyrazole-3,5-dicarboxylic acid, molecular formula is C5H4N2O4, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
General procedure: The deionized water (3 mL) was slowly dropped over the mixturesolution containing Cu(NO3)23H2O (0.2 mmol, 48 mg) andpyrazine (0.2 mmol, 16 mg) in water and DMF (4 mL, 1:1 v/v) in15 mL of glass vial. Then, the solution of pyrazole-3,5-dicarboxylicacid (0.2 mmol, 35 mg) in deionized water and ethanol (5 mL,1:1 v/v) was carefully layered over the mixture layer. Then, the vialwas sealed and allowed to stand undisturbed at room temperature. The blue crystals of 1 were obtained after 2 days.
The synthetic route of 3112-31-0 has been constantly updated, and we look forward to future research findings.
