Adding a certain compound to certain chemical reactions, such as: 19346-44-2, 2-Fluoro-3-nitro-5-methylpyridine, 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, Safety of 2-Fluoro-3-nitro-5-methylpyridine, blongs to pyridine-derivatives compound. Safety of 2-Fluoro-3-nitro-5-methylpyridine
3-Amino-2-fluoro-5-methylpyridine was prepared analogously from 2-fluoro-5-methyl-3-nitropyridine. This compound was obtained in 89 percent yield as white solid melting at 27-28.5 C.
