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. 89-40-7, name is 5-Nitroisoindoline-1,3-dione, This compound has unique chemical properties. The synthetic route is as follows., name: 5-Nitroisoindoline-1,3-dione
4-Nitrophthalimide (LOOGR) was taken into a beaker and dissolved using 300ML of dimethylformamide and 400ML of methanol. The solution was transferred into a 1L hydrogenation kettle and 20gr of wet Raney nickel catalyst was charged into the kettle. Hydrogenation was carried out initially at 20-40psi and 25-30C until the exothermic nature was over. Hydrogenation was further continued at 40-60psi pressure and 40-50C. After checking the completion of reaction by TLC, catalyst was removed by filtration and the solvents distilled off from the reaction mixture at 50-60C. The residue thus obtained was suspended in water (500ML) and filtered off to get a bright yellow crystalline compound of 4-aminophthalimide (78gr, 92.5%). Melting point: 294-5C.
According to the analysis of related databases, 89-40-7, the application of this compound in the production field has become more and more popular.
