(3,4-Methylenedioxy-6-nitrobenzald - Reference Information
| Use | organic synthesis intermediates. |
| production method | 60ml fuming nitric acid and 40ml glacial acetic acid are mixed into mixed acid under cooling, 25g of piperonal was added in portions to the mixed acid below 5 °c and the reaction was stirred for 6H. The reaction solution was poured into water to precipitate a precipitate. Filtration, washing, drying and recrystallization from ethanol gave 24g of 6-nitropiperonal in 74% yield. |
