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. 6332-56-5, name is 3-Nitropyridin-2(1H)-one, the common compound, a new synthetic route is introduced below. Formula: C5H4N2O3
a. 5-bromo-3-nitro-pyridine-2-ol-hydrobromide 3.6 ml of bromine are added dropwise to a suspension of 10.0 g (0.071 mol) of 2-hydroxy-3-nitro-pyridine in 25 ml of carbon tetrachloride whilst cooling with ice. The reaction mixture is refluxed for 2 hours. The solvent is distilled off in vacuo, the crystalline product is suction filtered and recrystallized from water. Yield: 7.5 g (35.1% of theory).
The synthetic route of 6332-56-5 has been constantly updated, and we look forward to future research findings.
