Application of 880870-13-3, The major producers of chemicals have been the Europe, Japan and China. Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a compound 880870-13-3, name is 5-Bromo-2-chloro-4-methoxypyridine. This compound has unique chemical properties. The synthetic route is as follows.
A solution of hydrogen chloride in 1,4-dioxane (4M, 0.020ml) was added to the solution of 5-bromo-2-chloro-4-methoxypyridine (0.18 g, 0.81 mmol) and methyl hydrazinecarboxyiate (0.30 g, 3.34 mmol) in ethanol (5 mi). The reaction mixture was heated in microwave reactor at 160 C for 9 hours. The mixture was cooled and evaporated to dryness. Purification of the evaporation residue by preparative reverse phase HPLC afforded 4.8 mg of 6-bromo-7-methoxy-[l ,2,4]triazolo[4,3-a]pyridin-3(2H)-one. 1H NMR (DMSO-de) delta: 12.24 (br s, 1H), 8.08 (s, 1H), 6.63 (s, 1H), 3.87 (s, 3H).
According to the analysis of related databases, 880870-13-3, the application of this compound in the production field has become more and more popular.
