Reference of 13091-23-1, 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 13091-23-1, name is 4-Chloro-3-nitropyridine. This compound has unique chemical properties. The synthetic route is as follows.
A solution of 4-chloro-3-nitropyridine (1.0 equiv.) and piperidine (2.0 equiv.) in ethanol, at a concentration of 0.5 M, was stirred at rt for 48 hours at which time the ethanol was removed in vacuo. The residue was partitioned between EtOAc (300 mL) and Na2CO3 (Sat) (75 mL), was washed further with H2O (50 mL), NaCl(Sat ) (50 mL), was dried over MgSO4, was filtered and the volatiles were removed in vacuo yielding 3- nitro-4-(piperidin-l-yl)pyridine (95%). LCMS (m/z): 207.7 (MH+); LC Rt = 1.60 min. 1H NMR (CDCl3): delta 8.80 (s, IH), 8.31 (d, J=5.7, IH), 6.84 (d, J=6.3, IH), 3.18-3.21 (m, 4H), 1.64-1.78 (m, 6H).
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 13091-23-1, 4-Chloro-3-nitropyridine.
