16013-85-7, 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 16013-85-7, name is 2,6-Dichloro-3-nitropyridine. This compound has unique chemical properties. The synthetic route is as follows.
Reference Example 15 2,6-dibromo-3-nitropyridine 2,6-Dichloro-3-nitropyridine (5.0 g) was dissolved in 25% hydrogen bromide-acetic acid solution (50 mL), and the mixture was stirred at 80C for 6 hr. The mixture was returned to room temperature, concentrated under reduced pressure to a liquid amount of about 20 mL, neutralized using a 12N aqueous sodium hydroxide solution at 0C, and extracted with ethyl acetate. The extract was washed with saturated brine, dried over anhydrous sodium sulfate, and concentrated under reduced pressure. The yellow solid obtained as a residue was washed with a mixed solvent of diisopropyl ether and hexane to give the title compound as yellow crystals (yield 5.6 g, including impurity). 1H-NMR (CDCl3) delta: 7.65 (1H, d, J = 8.4 Hz), 8.03 (1H, d, J = 8.4 Hz).
While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 16013-85-7, 2,6-Dichloro-3-nitropyridine.
