Adding a certain compound to certain chemical reactions, such as: 1074-98-2, 3-Methyl-4-nitropyridine 1-oxide, 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, 1074-98-2, blongs to pyridine-derivatives compound. Application In Synthesis of 3-Methyl-4-nitropyridine 1-oxide
The substance obtained in Process 1 (5.83 g) and sodium dichromate dehydrate (11.4 g) were slowly added to the concentrated sulfuric acid (39.5 mL) at 0 C. and reacted at room temperature for 4 hours. The reaction solvent was poured into ice (80 g) and water (100 mL) was slowly added thereto. Sodium hydrogen sulfite was further added thereto until the orange color of hexavalent chromium faded and the precipitate was filtered out. Ethyl acetated and 1N hydrochloric acid were added to the filtered out solid substance, extracted and washed. The layer of ethyl acetate was concentrated under reduced pressure to obtain the powder of 4-nitronicotinic acid-N-oxide (3.23 g).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,1074-98-2, its application will become more common.
