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. 113170-72-2, name is 3-Bromo-5-(trifluoromethyl)benzene-1,2-diamine, This compound has unique chemical properties. The synthetic route is as follows., Product Details of 113170-72-2
Example 21 0.2 mol of 3-bromo-5-trifluoromethyl-phenylene-diamine and 150 ml of trifluoroacetic acid were refluxed for 3 hours. For working up, excess trifluoroacetic acid was distilled off and the residue was partitioned between 100 ml of water and 300 ml of ethyl acetate. The organic phase was separated off, washed in succession with in each case 100 ml of aqueous sodium hydrogencarbonate solution and water, dried over sodium sulphate and concentrated in vacuo. The residue was purified by chromatography on silica gel (eluent: cyclohexane/ethyl acetate 1:1). This gave 4-bromo-6-trifluoromethyl-2-trifluoromethyl-1H-benzimidazole of melting point 149-151 C.
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 113170-72-2.
