2-{[(4-Amino-2,5-Dichlorophenyl)Sulfonyl]Amino}Ethanesulfonic Acid

This compound is 2 - [ [ ( 4-hydroxy-2,5-dioxobenzyl) blue] hydroxy] acetic acid. Its chemical properties are as follows:
This compound contains a carboxyl group, which is acidic because it can ionize hydrogen ions. Under suitable conditions, it can neutralize with bases to produce corresponding carboxylic salts and water. For example, when reacted with sodium hydroxide, the hydrogen ions in the carboxyl group combine with hydroxyl ions to form water molecules, and at the same time generate - [ [ ( 4-hydroxy-2,5-dioxobenzyl) blue] hydroxy] sodium acetate.
It also contains a hydroxyl group in its molecule, and the hydrogen atom of the hydroxyl group is relatively active. On the one hand, it can participate in the esterification reaction. When heated with carboxylic acid as a catalyst in concentrated sulfuric acid, the hydroxyl group will react with the carboxylic group of the carboxylic acid, remove a molecule of water, and form an ester group. On the other hand, the hydroxyl group can be oxidized, and under the action of an appropriate oxidant, it can be gradually oxidized to an aldehyde group, a carboxyl group, etc.
Furthermore, the compound has a benzene ring structure. The benzene ring has a certain stability and can undergo a substitution reaction. For example, in the presence of a catalyst, it can undergo halogenation reactions with halogen elements, and halogen atoms replace hydrogen atoms on the benzene ring; it can also nitrate with mixed acids of concentrated nitric acid and concentrated sulfuric acid, and nitro groups are introduced into the benzene ring.
In addition, due to the presence of multiple polar groups in the molecule, this substance should have a certain solubility in polar solvents. Its molecules can interact with each other through hydrogen bonds and other forces, which will also affect its melting point, boiling point and other physical properties.

In my opinion, the substance in question is 2 - [ [( 4-hydroxy-2,5-difluorophenyl) blue] hydroxy] acetic acid. This compound has applications in many fields.
In the field of pharmaceutical research and development, due to its unique chemical structure, it may become a key intermediate for the synthesis of new drugs.

To obtain 2 - [ [（ 4-hydroxybenzyl-2,5-dioxybenzyl) blue] hydroxy] acetic acid, there are many ways to synthesize it, and now I will describe one of them.
First take an appropriate amount of 4-hydroxybenzaldehyde, place it in a clean reaction vessel, add a certain amount of basic catalyst, such as potassium carbonate, at a suitable temperature, add 2,5-dioxybenzyl halide in a slow dropwise manner. This halide can be a bromide or a chloride, depending on the actual available raw materials. During the reaction, it is necessary to continuously stir to make the reactants fully contact and accelerate the reaction. After some time, the reaction is completed, and the (4-hydroxy-2,5-dioxybenzyl) compound can be obtained.
Then, transfer the compound to another reaction vessel, add an appropriate amount of oxidant, such as potassium permanganate or potassium dichromate, etc. Under specific reaction conditions, the hydroxyl group is oxidized to convert it into a carboxyl group, and then a carboxyl-containing (4-hydroxy-2,5-dioxybenzyl) derivative is obtained.
In this derivative, a suitable halogenated acetate is added, and in an alkaline environment, a nucleophilic substitution reaction occurs. After the reaction is completed, the acid is acidified to hydrolyze the ester group, and the final product is 2 - [ [（ 4-hydroxy-2,5-dioxybenzyl) blue] hydroxy] acetic acid.
However, there are many variables in the way of synthesis. The temperature, time and ratio of the reactants of the reaction need to be finely adjusted to obtain the ideal yield and purity. And the separation and purification of the product between each step is also very important. The commonly used methods include extraction, crystallization, column chromatography, etc., which are selected according to the characteristics of the product.

Looking at your words, I seem to ask "the price range of 2- [ (4-hydroxy-2,5-difluorophenyl) tracer] hydroxy] acetic acid in the market." However, the price of such chemicals often varies due to a variety of factors, which is difficult to determine.
First, the cost of raw materials has a great impact. If the raw materials for preparing this compound are scarce or difficult to obtain, the price will be high. If special reagents or extracts are required, if the sources are limited, the cost will be passed on to the finished product, resulting in higher prices.
Second, the complexity of the preparation process is also the key. If the preparation process requires multi-step reactions, strict conditions or complex technologies, the investment of manpower and material resources will increase, and the price will also increase. Fine chemical synthesis often requires precise control and high-end equipment, both of which increase costs.
Third, the market supply and demand relationship determines the price. If the demand is strong and the supply is limited, the merchant may raise the price for profit; conversely, if the supply exceeds the demand, the price may drop for promotional sales.
Fourth, the scale of production has an impact. Large-scale production can often reduce unit costs. Because resources such as equipment and manpower can be used more efficiently, the price or small-scale production is lower.
In summary, 2- [ (4-hydroxy-2,5-difluorophenyl) tracer] hydroxy] acetic acid is difficult to determine in the market price range, or fluctuates from a few to several hundred yuan per gram due to various factors. For the exact price, consult the relevant chemical product supplier or market platform.

In order to obtain the purity of this [ (4-hydroxy-2,5-dichlorophenyl) silver] hydroxyethyl ester acid, it is necessary to follow precise and complicated methods. First, appropriate separation and purification techniques should be used, such as distillation, recrystallization, chromatography, etc., to remove impurities and obtain a pure sample.
The method of distillation, according to the difference in boiling points of each component of the mixture, vaporizes and condenses successively to achieve the purpose of separation. Recrystallization is achieved by the change of solubility of the solute in different solvents or temperatures, so that the impurities remain in the mother solution, and the solute precipitates into crystals to improve its purity. Chromatography is achieved by the difference in the distribution coefficients of each component between the stationary phase and the mobile phase.
Then, the purity is determined by various analytical means. Chemical analysis methods can be used, such as titration, to select the appropriate titrant, and to measure the content of the target substance in the sample according to the chemical reaction metrological relationship. Instrumental analysis methods are also commonly used, such as high-performance liquid chromatography (HPLC), which determines the purity of the target substance according to the retention time and peak area; gas chromatography (GC), which is suitable for the determination of the purity of volatile organic compounds; mass spectrometry (MS), which can provide material structure and purity information.
When operating, it must be done strictly according to the specifications. From sample collection, preparation, to separation and analysis, all steps need to be carefully controlled to reduce errors and ensure accurate and reliable results. In this way, the purity of this [ (4-hydroxy-2,5-dichlorophenyl) silver] hydroxyethyl ester acid can be trusted.
