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. 550-44-7, name is 2-Methylisoindoline-1,3-dione, This compound has unique chemical properties. The synthetic route is as follows., Formula: C9H7NO2
3. Add N-methylphthalimide 19.3g (119.9mmol) and 40mL of 98% sulfuric acid in a 100mL round bottom flask, stir.After the solid was completely dissolved, 18.8 g (65.7 mmol) of dibromohydantoin was added, and the mixture was immediately sealed, and the reaction was further stirred at room temperature for 6 hours.The resulting clear reaction mixture was then poured into 200 mL of ice water.A large amount of white precipitate was precipitated immediately, suction filtered, and washed with deionized water until the filtrate was neutral.Vacuum drying to constant weight,28.2 g of 4-bromo-N-methylphthalimide as a white solid were obtained in a yield of 98.4%.
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 550-44-7.
