Adding a certain compound to certain chemical reactions, such as: 4966-90-9, 4-Hydroxy-6-methyl-3-nitropyridin-2(1H)-one, 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, 4966-90-9, blongs to pyridine-derivatives compound. Safety of 4-Hydroxy-6-methyl-3-nitropyridin-2(1H)-one
Part A: 2,4-Dihydroxy-6-methyl-3-nitropyridine was added to phosphorous oxychloride in a manner similar to Part B of Example 1 to afford 2,4-dichloro-3-nitro-6-methylpyridine as a pale yellow solid (mp 69-70 C.).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,4966-90-9, its application will become more common.
