What are the synthesis methods of 2- (4-ethoxy-2,3-difluoro-phenyl) -6-fluoro-phenol?

To prepare 2 - (4-ethoxy-2,3-difluorophenyl) -6-fluorophenol, the following ancient method can be used.

First take the appropriate starting material, one of which needs to contain 4-ethoxy-2,3-difluorophenyl structure, and the other needs to have a group that can react with the former and introduce 6-fluorophenol moiety. Halogenated aromatics are often used as starting materials, such as 4-ethoxy-2,3-difluorohalobenzene. The halogen atom can be bromine or chlorine. This halogenated benzene reacts with compounds containing 6-fluorophenol activity check point under the action of metal catalysts.

Commonly selected palladium catalysts, such as tetra (triphenylphosphine) palladium, etc., and ligands are also indispensable, such as tri-tert-butylphosphine, etc., can enhance the activity and selectivity of the catalyst. In the reaction system, alkali is also required. Potassium carbonate, sodium carbonate and other bases can adjust the pH value of the reaction environment and promote the reaction. Dissolve the raw materials, catalysts, ligands and bases, such as toluene, N, N-dimethylformamide, etc. in a suitable organic solvent to form a homogeneous reaction system.

When reacting, heat the system to an appropriate temperature, usually between 80 and 150 ° C according to the raw materials and reaction characteristics, and continue to stir to fully contact the reactants. The reaction process is monitored by thin-layer chromatography. When the raw material point disappears or reaches the expected degree of reaction, the heating is stopped.

After the reaction is completed, the reaction liquid is cooled, and the purified product is separated by conventional post-treatment means. The reaction solution is first diluted with water and extracted with an organic solvent, such as dichloromethane, ethyl acetate, etc., to collect the organic phase. The organic phase is dried with a desiccant such as anhydrous sodium sulfate to remove water. Then the organic solvent is removed by vacuum distillation to obtain a crude product. The crude product is further purified by column chromatography, and a suitable silica gel and eluent, such as a mixture of petroleum ether and ethyl acetate, are selected. The ratio is adjusted according to the polarity of the product, and finally the pure 2 - (4-ethoxy-2,3-difluorophenyl) -6 -fluoroph

What is the price range of 2- (4-ethoxy-2,3-difluoro-phenyl) -6-fluoro-phenol in the market?

What I am asking you is about the market price range of 2- (4-ethoxy-2,3-difluoro-phenyl) -6-fluoro-phenol. However, the price of the market is often changed due to factors such as time and place, supply and demand, and quality, and it is difficult to determine the exact number.

If it is in the chemical raw material market, the price of this compound may be affected by the cost of raw materials. The abundance of raw materials and the difficulty of obtaining them are all related to the cost, which in turn affects the price of the finished product. And the simplicity of the production process also affects the cost. If the process is complicated, special equipment and multiple processes are required, the cost will be high and the price will be high.

Furthermore, the market supply and demand relationship is the key. If the demand is strong and the supply is limited, the price will rise; conversely, if the supply exceeds the demand, the price may fall. Different regional markets, due to regional differences, transportation costs, local demand and other factors, prices also vary.

In addition, product quality is also a factor affecting price. High purity, high quality products, the price may be higher than ordinary.

Although it is difficult to determine its price range, you can consult chemical product suppliers, traders, or refer to chemical industry information platforms and market survey reports to obtain relatively accurate price information to help you make informed decisions.
