Reference of 3112-31-0, Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 3112-31-0, name is 1H-Pyrazole-3,5-dicarboxylic acid, This compound has unique chemical properties. The synthetic route is as follows.
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. Yield: 16 mg(34percent) based on copper salt. Anal. Calcd for Cu3C14H20N6O15: C,23.92; H, 2.87; N, 11.95. Found: C, 24.40; H, 2.80; N, 11.73percent.
