Adding a certain compound to certain chemical reactions, such as: 89-40-7, name is 5-Nitroisoindoline-1,3-dione, belongs to indolines-derivatives compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 89-40-7, SDS of cas: 89-40-7
Add 112.8 g of stannous chloride dihydrate and 70 mL of concentrated hydrochloric acid to a 500 mL three-necked flask, and stir until completely dissolved.19.2 g of 4-nitrophthalimide was added, and the reaction was stopped after reacting at 40 C for 1 h.The reaction solution was suction filtered to obtain a filter residue, and the filter residue was washed twice with 50 mL of concentrated hydrochloric acid and then dried.After washing twice with 50 mL of ethyl acetate, a second suction filtration was performed.The filter residue obtained by the second suction filtration was dried to obtain 14.9 g of 4-aminophthalimide yellow powder, and the yield was 92%.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 5-Nitroisoindoline-1,3-dione, other downstream synthetic routes, hurry up and to see.
