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. 116632-39-4, name is 5-Bromo-2-iodotoluene, This compound has unique chemical properties. The synthetic route is as follows., SDS of cas: 116632-39-4
Preparation 9 2-(2-Bromo-5-iodo-4-methylbenzyl) isoindoline-1,3-dione To a solution of 5-bromo-2-iodo toluene (512 mg, 1.72 mmol) in trifluoroacetic acid (5 mL) was added N-(hydroxymethy) phthalimide (305 mg, 1.72 mmol). The mixture developed a pink color. The solution was stirred at room temperature for 22 hours then concentrated sulfuric acid (1 mL) was added. The homogeneous solution was stirred for 18 hours at room temperature. Water was added and the precipitated solid collected by filtration and dried in a current of air (0.776 gm). This material, which by proton NMR analysis contained approximately 15% of an isomeric product, was carried forward to the following procedure without further purification. 1H NMR (400 MHz, CDCl3) delta7.85 (m, 2H) 7.76(m, 2H) 7.5 (s, 1H) 7.38(s, 1H) 4.84(s, 2H) 2.31(s, 3H). GC-MS calc. 455, found 455.
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 116632-39-4.
