Synthetic Route of 570-22-9,Some common heterocyclic compound, 570-22-9, name is 1H-Imidazole-4,5-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: 10 mL ethanol solution of 2.0 mmol metal salt was added into 10 mL ethanol solution of 2.0 mmol 4,5-imidazole dicarboxylic acid. Having blended the mixture under reflux for 1 h, methanol solution of 1.0 mmol NaOH was put into hot mixture drop by drop. After 5 h under reflux, solvent of the solution was removed, precipitate was filtered. The precipitates were washed with methanol 3 times and dried in 105 C. Molecular structures of complexes obtained from the reaction of 4,5-imidazole dicarboxylic acid ligand with metal salts were summarized in Fig. 2.1.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 1H-Imidazole-4,5-dicarboxylic acid, its application will become more common.
