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 13472-81-6, name is 3,5-Dibromo-2-hydroxypyridine. This compound has unique chemical properties. The synthetic route is as follows. Formula: C5H3Br2NO
3,5-Dibromo-2-hydroxypyridine (9.36 g, 37 mmol; purchased from Tokyo Chemical Industry Co., Ltd.), 1,4-butane sultone (6.58 g, 48.3 mmol), and NaOH (1.97 g, 49.3 mmol) were added to 160 mL of ethanol, and the mixture was stirred for 24 h at 60 C. The white precipitate was separated by filtration, and recrystallization from THF containing a small amount of water gave Monomer-1 (7.17 g, 47%). 1H NMR (300 MHz, D2O) delta: 7.93 (d, J = 2.4 Hz, 1H), 7.77 (d, J = 2.4 Hz, 1H), 3.90 (t, J = 6.9 Hz, 2H), 2.78 (t, J = 7.5 Hz, 2H), 1.71 (m, 2H), 1.60 (m, 2H). IR (KBr) 1656, 1593, 1188, 1052 cm-1. Anal. Calcd for C9H10Br2NNaO4S: C, 26.30%; H, 2.45%; Br, 38.88%; N, 3.41%; S, 7.80%. Found: C, 25.80%; H, 2.52%; Br, 39.04%; N, 3.34%; S, 7.71%.
With the rapid development of chemical substances, we look forward to future research findings about 13472-81-6.
