5-Bromo-3-nitropyridin-2(1H)-one is a biochemical reagent that can be used as a biological material or organic compound for life science related research. | [Synthesis]
GENERAL METHOD: 2-amino-3-nitro-5-bromopyridine (0.015 mol) was dissolved in 70% sulfuric acid under cooling in an ice bath. A solution prepared from sodium nitrite (1.24 g) dissolved in water (8 mL) was slowly added dropwise in the range of 0-5°C, keeping the reaction temperature constant. After the dropwise addition, the reaction mixture was allowed to warm up gradually to room temperature and stirred continuously at that temperature for 3 hours. After completion of the reaction, the resulting precipitate was separated by filtration, washed well with deionized water and finally dried under vacuum at 60 °C overnight. | [References]
