Related Products of 4858-85-9, 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. 4858-85-9, name is 2,3-Dichloropyrazine belongs to Pyrazines compound, it is a common compound, a new synthetic route is introduced below.
Dissolve 2,3-dichloropyrazine (20 g, 0.134 mol) in ethanol, and add hydrazine hydrate (21 g, 0.42 mol) in small portions for multiple times and reflux at 85 C.The reaction was detected by TLC until the reaction was complete. After the reaction solution was cooled, it was added to ice water and stirred.The precipitated solid was suction-filtered and the filter cake was dried to obtain 16.8 g of a yellow-yellow powder with a yield of 84.1%.
The synthetic route of 2,3-Dichloropyrazine has been constantly updated, and we look forward to future research findings.
