The synthesis of 4-bromo-2 - (trifluoromethoxy) phenylacetic acid is an important research direction in the field of organic synthesis. The synthesis route can be gradually achieved by the following steps.
The starting materials are 4-bromo-2-hydroxyphenylacetic acid and trifluoromethylation reagents. These two, under suitable reaction conditions, undergo etherification reaction to generate the target product 4-bromo-2 - (trifluoromethoxy) phenylacetic acid.
First, dissolve 4-bromo-2-hydroxyphenylacetic acid in a suitable organic solvent, such as N, N-dimethylformamide (DMF). To this solution, add an appropriate amount of alkali, such as potassium carbonate. The action of the alkali is to deprotonate the hydroxyl group and enhance its nucleophilicity.
Then, slowly add a trifluoromethylating agent, such as trifluoromethylsulfonic anhydride. The reaction temperature needs to be carefully controlled, usually between low temperature and room temperature. In this reaction process, trifluoromethoxy anion undergoes nucleophilic substitution reaction with the deprotonated hydroxyl group of 4-bromo-2-hydroxyphenylacetic acid to form the intermediate of 4-bromo-2- (trifluoromethoxy) phenylacetic acid. After the
reaction is completed, the reaction mixture is post-treated. The product is diluted with water first, and then extracted with an organic solvent. Commonly used extractants include ethyl acetate. The extract is dried with anhydrous sodium sulfate to remove the moisture in it. After that, the organic solvent is removed by vacuum distillation to obtain a crude product.
The crude product can be further purified by column chromatography or recrystallization. The suitable silica gel column was selected by column chromatography, and the mixed solvent of n-hexane and ethyl acetate was used as the eluent; the appropriate solvent was selected by recrystallization method, such as ethanol-water mixed solvent, so that the product crystallized and precipitated, and finally obtained high-purity 4-bromo-2 - (trifluoromethoxy) phenylacetic acid. This synthesis method has clear steps and mild conditions, which can effectively prepare the target product, and is of great practical value in the field of organic synthesis.

4-Bromo-2- (trifluoromethoxy) phenylacetic acid, the price of this product in the market is difficult to determine. The price of the cover often varies due to many reasons, and it cannot be generalized.
Looking at the price of various chemical products, the availability of its raw materials is related to its price. If the raw material of 4-bromo-2- (trifluoromethoxy) phenylacetic acid is easy to obtain and abundant, the price will be flat. However, if the raw material is rare and difficult to find, its price will be high. For example, if the raw material is collected in a remote place, it is difficult to harvest and transport, the cost will increase, and the price will also rise.
Furthermore, the preparation technique also has a great impact. A refined method can save time, reduce its cost, and lower the price. If the method is clumsy and the material is time-consuming, the price will be high. If the ancient method is prepared, the steps are cumbersome, and the labor is twice as expensive, its price is not easy.
The supply and demand of the city is also the main reason. If there are many users, the demand is too much, and the price will rise. If the market is full of goods and the supply exceeds the demand, the price will fall.
There are various factors, such as tax increases and decreases, freight levels, and the current situation to rule out chaos, etc., all of which can change the price. If the tax is heavy, the merchant will increase the price to make up for it; if the freight increases, the cost will also increase and the price will be high. In times of trouble, the circulation of goods will be blocked, and the price will be unstable.
From this perspective, if you want to know the exact price of 4-bromo-2 - (trifluoromethoxy) phenylacetic acid, you can only get it after reviewing the changes in raw materials, preparation, supply and demand, and various foreign affairs. It is difficult to judge the market price based on your imagination.

4-Bromo-2 - (trifluoromethoxy) phenylacetic acid, this is an organic compound. Its storage conditions are crucial, which is related to the stability and quality of the compound.
