Reference of 19798-80-2, 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 19798-80-2, name is 4-Chloropyridin-2-amine. This compound has unique chemical properties. The synthetic route is as follows.
To a solution of 2-amino-4-chloropyridine (150 g, 0.78 mol) in DMF (1.5 L) was added NIS (341 g, 1.52 mol) and the reaction mixture stirred at RT for 18 h before being concentrated in vacuo to 300 mL volume. The resultant residue was poured into 10% aqueous sodium thiosulfate solution (1.2 L), stirred for 15 min and the precipitate formed collected by filtration, washed with water then dried at 35 C. in vacuo to give the title compound as a pale brown solid (185 g, 62%). 1H NMR 400 MHz (CDCl3) delta: 8.33 (1H, s), 6.68 (1H, s), 4.52 (2H, s).
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 19798-80-2, 4-Chloropyridin-2-amine.
