To prepare 8- (3,4-dioxyisobenzofuran-2 (1H) -yl) benzaldehyde, the method is as follows:
First take catechol and react it with chloroacetic acid in an alkaline environment to obtain 3,4-dihydroxyphenylacetic acid. In this step, the temperature should be controlled moderately and stirred evenly to make the reaction sufficient.
Then the 3,4-dihydroxyphenylacetic acid is co-heated with acetic anhydride to undergo acetylation reaction to obtain 3,4-diacetoxyphenylacetic acid. When reacting, pay attention to the heat and do not cause the product to decompose due to excessive temperature.
Next, 3,4-diacetoxyisobenzofuran-1 (3H) -one is obtained by intramolecular cyclization of 3,4-diacetoxyisobenzofuran-1 (3H) -one with concentrated sulfuric acid as catalyst. In this process, the amount of concentrated sulfuric acid needs to be accurate and the drip rate should be appropriate.
Subsequently, 3,4-diacetoxyisobenzofuran-1 (3H) -one is hydrolyzed, and the acetyl group is deacetylated to obtain 3,4-dihydroxyisobenzofuran-1 (3H) -one. The hydrolysis conditions are mild to maintain the stability of the product.
Then oxidize 3,4-dioxyisobenzofuran-1 (3H) -one to 3,4-dioxyisobenzofuran-2 (1H) -one with a suitable oxidant. The choice of oxidant needs to be cautious, depending on the reaction conditions and product requirements.
Finally, the Suzuki coupling reaction of 3,4-dioxyisobenzofuran-2 (1H) -one with p-formylphenylboronic acid results in 8- (3,4-dioxyisobenzofuran-2 (1H) -yl) benzaldehyde. In the reaction, the choice of catalyst, base and reaction solvent is crucial, which affects the success or failure of the reaction and the yield.
Each step of the reaction requires fine operation, attention to the control of reaction conditions, such as temperature, pH, reaction time, etc., and the separation and purification of the product cannot be ignored, so as to obtain the target product efficiently.

Today there are 8- (3,4-dioxy isosquinone acid-2 (1H) -ylthiazolyl) square acids in the market, what is the price? I will imitate the body of "Tiangong Kaiwu" and describe it in ancient text.
Gai Wen is trading in various stores, and each product has a price. The price of this 8- (3,4-dioxy isosquinone acid-2 (1H) -ylthiazolyl) square acid in the market is difficult to determine. The level of its price depends on many factors.
One is the place where it comes from. If the production is good, the materials are abundant, and the production is convenient, the price will be flat. If its source is sparse, it is difficult to harvest, and the system is cumbersome, the price will increase.
Second, the quality is good or bad. Those with high purity and few impurities are excellent products, and the price is not cheap. If it contains a lot of heterogeneity, the quality is not pure, and the price should be inferior.
Third, the supply and demand of the city. If there are many people who want it, and there are few people who supply it, the price will go up; if supply exceeds demand, the price will automatically drop.
Fourth, the cost of production and sales. Fees such as harvesting, refining, storage and transportation, taxes, etc. are all included in the price. The cost is high if it is complicated, and the price is low if it is simple. < Br >
Therefore, if you want to know the exact price of this 8- (3,4-dioxy isosquanoic acid-2 (1H) -ylthiazolyl) square acid in the market, you should carefully consider its source, quality, supply and demand, and the cost of production and sales. In the market, Jia people also weigh various ends according to the changes of time to set the price. Or you can consult the pharmacy and chemical shop, and negotiate with Jia to get the exact price.

"Tiangong Kaiwu" says: "8 -% 283% 2C4 - dioxoisobutyric acid - 2% 281H% 29 - thiazolyl% 29 - butyric acid light is a matter of safety and is quite important. The material used in this light must be pure in quality. If there are impurities, the light color may be different, and it is prone to danger.
Those who make this light should choose the best material with a strict method. During operation, it is necessary to observe changes in temperature and heat. If the temperature is too high, the material will be vulnerable, and the light will be abnormal; if the temperature is too low, the reaction will be slow, and the light will not be effective.
Also, the environment where this light is located should also be paid attention to. If you are in a humid place, the light body is perishable, causing the light color to be dim, or even extinguished; if you are in a hot and dry place, there is a risk of explosion.
Furthermore, the person who handles it must be familiar with its skills and be careful. A slight mistake will lead to disaster. You must follow the law, and you must not act on your own. In this way, the light of 8 -% 283% 2C4 -dioxoisobutyric acid - 2% 281H% 29 -thiazolyl% 29 butyric acid will be safe for your needs, and there will be no safety. "
