These common heterocyclic compound, 570-22-9, name is 1H-Imidazole-4,5-dicarboxylic acid, its 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. COA of Formula: C5H4N2O4
The complex was synthesized by hydrothermal method. A mixture of Zn(NO3)2.6H2O (0.47 g; 1.6 mmol), H3idc (0.25 g, 1.6 mmol) and water (30 mL) was sealed in a 45 mL Parr brand teflon-linedacid digestion bomb and heated at 180 C for 5 days, and then cooled to room temperature at a rate of 5 C/h. Pale yellow crystals of 1 were obtained (yield: 0.195 g, 73% based on Zn(NO3)26H2O). Anal. Calc. for C10H2N4O8Zn3: C, 23.91; H, 0.40; N, 11.15. Found:C, 23.90; H, 0.52; N, 10.90%. IR data (KBr, cm1): 3531m, 3359m, 3120m, 1589s, 1544s, 1474s, 1477s, 1384s, 1296m, 1253s, 1205m, 1107s, 1020w, 871m, 835m, 792m, 661m, 540w.
The synthetic route of 1H-Imidazole-4,5-dicarboxylic acid has been constantly updated, and we look forward to future research findings.
