EPA chemical information | Information provided by: ofmpub.epa.gov (external link) |
application | 5-nitroindazole can be used as an intermediate in organic synthesis and pharmaceutical intermediate for laboratory research and development processes and synthesis of pharmaceutical and chemical industries. |
Use | Used as a photosensitive chemical Organic synthesis intermediate. |
production method | dissolve 55 g2-amino -5-nitrotoluene in 2.5L glacial acetic acid, cool, add 25g sodium nitrite and 60ml water to prepare the solution, and the reaction temperature does not exceed 25 ℃. The generated yellow precipitate is filtered out, the reaction solution is placed for 3 days and then concentrated under reduced pressure. The residue is stirred with 200ml of water and pasty, filtered, the filter cake is washed with cold water, dried, and recrystallized with methanol to obtain 42-47g5-nitroindazole with a yield of 72%-80%. |
