In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 150-78-7 as follows. Quality Control of 1,4-Dimethoxybenzene
General procedure: To a stirred solution of starting compound (0.5-1.2 mmol) in DMF-H2O (95:5, v/v, 8-12 mL) mixture was added NBS (4.0-4.2 mmol) at room temperature. The contents were stirred at room temperature about 10 min and then heated for appropriate duration mentioned in Table 2. Progress of the reaction in every case was monitored by TLC analysis. After completion of the reaction, the reaction mixture was cooled to room temperature and quenched with aqueous NaHCO3 (20%, 20-30 mL) solution. The insoluble precipitate was isolated by filtration and dried in vacuo. It was further purified by either recrystallization with ethyl acetate/n-hexane mixture or short pad silica gel column chromatography led to pure product.
According to the analysis of related databases, 150-78-7, the application of this compound in the production field has become more and more popular.
