9/7/21 News Extended knowledge of 15108-18-6

The synthetic route of 2-Hydrazinyl-1H-benzo[d]imidazole has been constantly updated, and we look forward to future research findings.

Electric Literature of 15108-18-6, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 15108-18-6, name is 2-Hydrazinyl-1H-benzo[d]imidazole belongs to imidazoles-derivatives compound, it is a common compound, a new synthetic route is introduced below.

To a solution of 2-hydrazinobenzimidazole (750 mg;5mmol) in a mixture of 10mL of water and 0.75mL of concentrated HCl was gradually added 1,1,3,3-tetramethoxypropane(820mL; 5mmol). The resulting mixture was heated at reflux for 2 h, then was allowed to cool and filtered.The filtrate was neutralised with solid potassium carbonate,causing the product to precipitate as a pale tan solid, which was filtered and dried in vacuo.

Extended knowledge of 15108-18-6

The synthetic route of 15108-18-6 has been constantly updated, and we look forward to future research findings.

Application of 15108-18-6,Some common heterocyclic compound, 15108-18-6, name is 2-Hydrazinyl-1H-benzo[d]imidazole, molecular formula is C7H8N4, 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.

To a solution of 2-hydrazino-1 H-benzimidazole (5.0 g, 33.7 mmol) in ethanol (30 ml) is added sequentially triethylamine (5 ml, 33.7 mmol) and N-cyanoformimidic acid ethyl ester (3.3 g, 33.7 mmol) with cooling. After stirring for 2 hours at 0C the resulting precipitate is filtered with suction and dried to give 3-, amino-2-(1 H-benzimidazol-2-yl)-1, 2, 4-triazole. 1H- NMR (400 MHz, d6-DMSO) : 13.0 (s, 1 H) ; 7.77 (s, 1 H) ; 7.70 (m, 2H); 7.50 (m, 2H); 7.20 (s, 2H).

The synthetic route of 15108-18-6 has been constantly updated, and we look forward to future research findings.
