Disodium 6-Hydroxy-5-[(E)-(2-Methoxy-5-Methyl-4-Sulfonatophenyl)Diazenyl]Naphthalene-2-Sulfonate

This is the chemical substance disodium 6-hydroxy-5- [ (E) - (2-methoxy-5-methyl-4-sulfophenyl) azo] naphthalene-2-sulfonate. It has a wide range of uses and is often used as an important raw material for synthetic dyes in the field of dyes. Because of its special chemical structure, it can give fabrics a variety of colors, such as bright red, orange, etc., and has good color fastness after dyeing. It plays a key role in the textile printing and dyeing industry. In analytical chemistry, it can be used as an analytical reagent. By virtue of the color reaction with specific substances, it is used for qualitative and quantitative analysis, such as the detection of metal ions, which helps to determine the composition and content of substances. In scientific research and exploration, it is also an important tool. Researchers use its chemical properties to study chemical reaction mechanisms and molecular interactions, which help to deeply understand chemical processes and provide theoretical support and technical means for new material research and development, drug synthesis and other fields.

This is a disodium 6-hydroxy-5- [ (E) - (2-methoxy-5-methyl-4-sulfophenyl) azo] naphthalene-2-sulfonate, which is an organic compound. This substance has multiple chemical properties:
First, it shows good solubility in water because it contains a sulfonate group (-SO 🥰 Na). This group is hydrophilic and can form hydrogen bonds with water molecules, which helps the compound disperse and dissolve in aqueous media, and then is used in aqueous systems such as dyes and coatings.
Second, the molecule contains an azo group (-N = N-), which gives the compound a certain color. The nitrogen-nitrogen double bond in the azo group can absorb visible light of specific wavelengths, cause electron transitions, and show specific colors. It is often used to prepare dyes. By precisely adjusting the molecular structure, different color dyes can be obtained.
Third, the structure of naphthalene ring and benzene ring gives the compound a certain stability. The aromatic ring system has a conjugated π electron cloud, which enhances molecular stability. At the same time, this kind of rigid structure affects the accumulation and arrangement of molecules, and has an effect on the physical properties of the compound such as melting point and crystallinity.
Fourth, the presence of hydroxyl groups (-OH) adds molecular reactivity. Hydroxyl groups can participate in a variety of chemical reactions, such as esterification, etherification and other reactions, providing the possibility for the derivatization of compounds. Through chemical modification, its application range can be further expanded, such as the preparation of derivatives with special properties.
Fifth, methoxy (-OCH) as a power supply group can change the electron cloud density of the benzene ring, affecting the electronic properties and reactivity of the compound. This has an impact on the molecular spectral properties and chemical reaction selectivity, such as affecting the distribution of azo electron clouds, resulting in changes in the absorption spectrum.

The preparation of this disodium 6-hydroxy-5- [ (E) - (2-methoxy-5-methyl-4-sulfophenyl) azo] naphthalene-2-sulfonate is very important, and there are many things to pay attention to.
The quality of the first raw material, the materials used must be pure and free of impurities. 2-methoxy-5-methyl-4-sulfoaniline and other raw materials, if they contain impurities, will cause the product to be impure, affecting its performance and use. When purchasing a material, check its quality carefully and ask for the quality inspection book to ensure that it meets the required standards.
The rule of reaction cannot be ignored. Temperature is a crucial item. For this reaction, if the temperature is too high, the reaction will be too fast, and it is easy to produce by-products; if the temperature is too low, the reaction will be slow and time-consuming. When the temperature is precisely controlled according to the nature of the reaction, it is often kept at an appropriate temperature with a precise temperature control device. And the pH value of the reaction is also important. Improper pH can cause the reaction to be difficult or the product to change. Therefore, when the reaction is carried out, the pH needs to be constantly measured and adjusted with an acid-base agent to ensure that it is at an appropriate value.
The matter of stirring is also about success or failure. Stir well, and the materials will be mixed evenly, and the reaction will be fast and uniform. If the stirring is not uniform, some raw materials may be difficult to react, resulting in uneven products and a decrease in yield. When using a suitable stirring device, adjust the speed to suit, and ensure that the reaction system is well miscible. The separation and purification work after
also requires careful attention. In the product, or containing unsuitable materials or by-products, it must be removed by appropriate methods. Crystallization, chromatography, etc. can be used to remove impurities to obtain a pure product. In pure chemical industry, pay attention to the fineness of the operation, so as not to damage the product.
In summary, the preparation of this disodium 6-hydroxy-5- [ (E) - (2-methoxy-5-methyl-4-sulfophenyl) azo] naphthalene-2-sulfonate, from raw materials to finished products, step by step to be careful, in order to obtain a good material for where needed.

I don't know what you mean by "Disodium+6-Hydroxy-5-%5B%28E%29-%282-Methoxy-5-Methyl-4-Sulfonatophenyl%29Diazenyl%5DNaphthalene-2-Sulfonate" to the market price. This is a rather professional chemical substance, and its market price often changes due to many factors.
First, the quality of the product has a great impact on the price. If the product is pure and has few impurities, and meets high standards, the price will be high; if the quality is slightly inferior and contains more impurities, the price will be low.
Second, the situation of supply and demand also affects the price. If the market has a strong demand for this product and the supply is limited, the price will rise; conversely, if the demand is low, the supply will be abundant, and the price will fall.
Third, the manufacturing cost is also the key. The price of raw materials, the simplicity of the production process, energy consumption, etc., are all related to the cost, which in turn affects the selling price.
Fourth, the place and channel of sales are different, and the price is also different. In prosperous places and formal channels, the price may be high; in remote places and informal channels, the price may be low.
However, I have not received the exact market information, so it is difficult to determine the market price. If you want to know the exact price of this product, you can consult chemical reagent suppliers, chemical product trading platforms, or consult with industry experts to get a more accurate price.

"Tiangong Wuwu" was completed in the Ming Dynasty for ten years. According to the ancient Chinese saying, it is a matter of hundreds of techniques and techniques. However, I have not yet discovered the amount of "Disodium+6-Hydroxy-5-%5B%28E%29-%282-Methoxy-5-Methyl-4-Sulfonatophenyl%29Diazenyl%5DNaphthalene-2-Sulfonate". This name is used for the generation, and there are no chemical names. "Tiangong Wuwu" has not yet realized this situation, and it is not mentioned that this material is not.
In terms of generation, there are no synthetic dyes or materials in the composition, and the amount of it depends on the use. If used for printing and dyeing, color fastness, solubility, dispersion, etc. need to be considered. The color fastness needs to be high, such as water resistance, friction resistance, light resistance, etc., to meet the needs of different materials and use scenarios; the solubility should be able to dissolve well in specific printing and dyeing solutions to avoid clogging the mouth or causing uneven dyeing; the dispersibility should be evenly dispersed in the dye solution, so that the dyeing is uniform.
If used for other industrial purposes, such as raw materials, etc., in addition to the above characteristics, there may be requirements for compatibility and quality of other components of the raw materials. It is necessary to ensure the storage of the raw materials during the period and the performance during use. It is not difficult to produce, sink, etc. Therefore, the amount of raw materials is determined by its application domain and customer needs.
