1,2,3-Benzenetriol, 5-broMo- Chemical Properties,Usage,Production
Application
5-Bromo-1,2,3-benzenepyrogallol can be used as an organic synthesis intermediate and a pharmaceutical intermediate, mainly in laboratory research and development processes and chemical production processes.
Synthesis
2675-79-8
16492-75-4
General procedure for the synthesis of 5-bromo-1,2,3-benzenetriol from 1-bromo-3,4,5-trimethoxybenzene: 7.44 g (30.24 mmol) of 3,4,5-trimethoxy-1-bromobenzene and 70 mL of anhydrous methylene chloride were added to a four-necked flask and the mixture was cooled to -78 °C. Subsequently, 325.0 g (99.8 mmol) of boron tribromide (BBr3) was slowly added dropwise, and after completion of the dropwise addition, the reaction mixture was continued to be stirred at -78 °C for 1 hour. Upon completion of the reaction, the mixture was slowly warmed to room temperature and carefully poured into 200 mL of ice water to precipitate the product. The precipitate was collected by filtration to give 6.8 g (quantitative yield) of 5-bromo-1,2,3-benzenetriol as a white powder. The m/z of 5-bromo-1,2,3-benzenetriol was analyzed by mass spectrometry to be 206.01 ([M + H]+).
