methyl 6-bromobenzo[b]thiophene-2-carboxylate

The method of preparing methyl 6-bromobenzo [b] thiophene-2-carboxylic acid ester is often achieved in several ways in the ancient organic synthesis technology.
First, it can be obtained by esterification of 6-bromobenzo [b] thiophene-2-carboxylic acid with methanol. In this method, an appropriate amount of 6-bromobenzo [b] thiophene-2-carboxylic acid is first placed in the reaction vessel, followed by a certain amount of methanol. In order to promote the speed of this reaction, strong acids are often used as catalysts, such as concentrated sulfuric acid. When reacting, it is necessary to control the temperature to a suitable range, and it can generally be carried out under the condition of heating and reflux to make the two fully react. After some time, the reaction is completed, and the impurities are removed by conventional separation and purification methods, such as extraction, distillation, recrystallization, etc., to obtain pure methyl 6-bromobenzo [b] thiophene-2-carboxylate.
Second, it can also be prepared by reacting 6-bromobenzo [b] thiophene-2-formyl chloride with sodium methoxide. First prepare 6-bromobenzo [b] thiophene-2-formyl chloride, which can be obtained by the action of 6-bromobenzo [b] thiophene-2-carboxylic acid with chlorination reagents such as dichlorosulfoxide. After 6-bromobenzo [b] thiophene-2-formyl chloride is prepared, it is slowly dripped into a solution containing sodium methoxide. This reaction is relatively fast, but it is also necessary to pay attention to the control of reaction conditions, such as temperature and drip speed. After the reaction is completed, the target product is obtained by the same separation and purification method, such as filtration, washing, drying and other steps. < Br >

I have not heard of the exact price of "methyl 6 - bromobenzo [b] thiophene - 2 - carboxylate" in the market. This is a chemical substance, and its price fluctuates due to various factors such as purity, supply and demand, and difficulty in preparation.
If its purity is excellent, the preparation is difficult, and there are many applicants and few suppliers, the price will be high; if the purity is slightly lower, the preparation is easier, and the supply is excessive, the price will be low.
In the world of "Tiangong Kaiwu", such chemically synthesized substances have not yet been available, so it is difficult to determine the price according to their method. Today, if you want to know the price of this product, you should consult the chemical reagent supplier or check it in detail on the chemical trading platform to get its approximate price range. However, there is no exact information at present, and it is difficult to determine the price range. It should be noted that different suppliers and different purchase quantities have different prices. To get an accurate price, you must inquire and compare it many times.
