Adding a certain compound to certain chemical reactions, such as: 23056-47-5, 2-Bromo-4-methyl-5-nitropyridine, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound, Product Details of 23056-47-5, blongs to pyridine-derivatives compound. Product Details of 23056-47-5
2-Bromo-4-methyl-5-nitropyridine (2.5g, 11.58mmol) was dissolved in concentrated sulfuric acid (25mL), cooled to ice bath 0C, chromium trioxide (3.88g, 38.8mmol) was added. It was slowly warmed to room temperature and stirred overnight. The reaction mixture was poured into ice water (75 mL), stirred for 10 minutes and suction filtered to give a white solid (2.5g, yield: 87.8%).
At the same time, in my other blogs, there are other synthetic methods of this type of compound,23056-47-5, 2-Bromo-4-methyl-5-nitropyridine, and friends who are interested can also refer to it.
