Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 39989-43-0, name is 3,5-Dichlorobenzylamine, This compound has unique chemical properties. The synthetic route is as follows., SDS of cas: 39989-43-0
1 -(2-(3 ,5-DichloiObenzylamino)-4-fluoro-nitrobenzene:; A mixture of 2,4-difluoronitrobenzene (5.0 mmol), 3,5-dichlorobenzylamine (5.0 mmol), N, N- diisopropylethylamine (10.0 mmol) and acetonitrile (25 mL) was heated at reflux for 18 h, cooled and concentrated in vacuo. The residue was dissolved in ethyl acetate; this solution was washed with water, dried over Na2SO4 and concentrated in vacuo. The residue was purified by flash column chromatography on silica gel using 5 % ethyl acetate in hexanes as eluent to yield the title compounds as a yellowish solid (46 %). 1H NMR (400 MHz, CDCl3): delta 9.28 (br s, 1 H)5 7.88 (m, 1 H)5 7.34 (s, 1 H)5 7.22 (s, 2 H), 6.44 (m, 1 H), 6.30 (dd, 1 H), 4.43 (d, 2 H).
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 39989-43-0.
