This is a disodium 8-phenylamino-5- [[4- (3-sulfophenyl) azo-1-naphthyl] azo] naphthalene-1-sulfonate, which has a wide range of uses.
In the field of dyeing, it can be used as a dye. Because of its special molecular structure, it can form a stable bond with fiber molecules, giving rich colors to fabrics. Whether it is natural fibers such as cotton and linen, or synthetic fibers such as polyester, it can be evenly colored by it, and the color is bright and the color fastness is very good. After many washes and rubbing, the color is still lasting and bright.
can be used as an indicator in analysis and detection. Because it is sensitive to changes in a specific chemical environment, when a specific substance or condition changes, the color will change significantly, so it can accurately indicate the chemical reaction process or the presence or absence of a specific substance. For example, in some acid-base titration reactions, the color mutation can be used to keenly indicate the titration endpoint, which can help the experimenter accurately judge the completion time of the reaction and improve the accuracy of the analysis results.

By connecting with biological macromolecules such as proteins and nucleic acids, and tracking the activity trajectory and distribution of biomolecules through their color or fluorescence characteristics under a microscope, it can help researchers to deeply explore the complex physiological processes and molecular mechanisms in organisms, providing key tools for life science research.

When preparing the bisodium salt 8-phenylamino-5- [[4- (3-sulfophenyl) azo-1-naphthyl] azo] naphthalene-1-sulfonate, many matters need to be paid attention to.
First and foremost, the selection of raw materials must be carefully selected. The purity and impurity content of the aniline, naphthalene compounds and phenyl compounds containing sulfonyl groups used have a profound impact on the quality of the product. Too many impurities, or the increase of reaction by-products, reduce the purity of the product, and affect the subsequent application.
The reaction conditions cannot be ignored. Temperature control is extremely critical, and different reaction stages may require different temperatures. If the temperature rise is too fast or too slow, it may cause the reaction to deviate from the expected path, or cause the reaction rate to be poor. The reaction time must also be accurately controlled. If it is too short, the reaction will not be fully functional and the product generation will be insufficient. If it is too long, it may cause an overreaction and destroy the product structure.
Furthermore, the choice of reaction solvent is also very knowledgeable. The selected solvent needs to be able to dissolve the raw materials and products well and have no adverse effects on the reaction. At the same time, its physical properties such as boiling point and volatility also need to meet the needs of the reaction, so that the separation and purification after the reaction can be carried out.
Separation and purification steps are also crucial. The product is often mixed with unreacted raw materials, by-products and other impurities. Appropriate separation methods, such as crystallization, extraction, chromatographic separation, etc., are required to obtain high-purity products. When operating, follow the standard process to prevent product loss or secondary pollution.
Finally, safety protection must not be slack. During the reaction process, toxic and harmful raw materials, solvents, or irritating gases may be involved. Operators must take protective measures, such as wearing protective equipment and operating in a well-ventilated environment, to ensure their own safety and health.

This is a product called disodium 8-anilinyl-5- [4 - (3-sulfonylphenyl) azo-1-naphthyl] azo] naphthalene-1-sulfonate, but its market price range is difficult to say exactly. Due to the ease of the market, prices are affected by various factors.
First, the purity of this product has a huge impact on the price. If the purity is high and the impurities are rare, it is suitable for high-end and fine chemical synthesis, scientific research experiments and other important uses, and its price is high; on the contrary, the purity is slightly inferior, only for ordinary industrial uses, and the price is low.
Second, the state of supply and demand is also the key. If there are many people in the market, but the supply is limited, the so-called "rare things are more expensive", and the price will rise; if the supply exceeds the demand, the merchant may reduce the price in order to sell their goods.
Third, the cost of production cannot be ignored. The price of raw materials, production methods, manpower costs, transportation costs, etc. will all weigh on the cost, which will then affect the price. If the raw materials are rare and the craftsmanship is complicated, the cost will be high, and the price will rise accordingly.
Fourth, brand and word-of-mouth are also related to the price. Well-known brands, with their reputation as the most important, product quality is stable and good, and customer trust is strong, their price may be higher than others.
To sum up, the market price of disodium 8-anilinyl-5- [[4- (3-sulfophenyl) azo-1-naphthyl] azo] naphthalene-1-sulfonate is difficult to generalize, or from a low price of several yuan per kilogram to a high price of several hundred yuan per kilogram, depending on how the above factors interact.

The method of hiding is related to the long-term storage without damage. For this "disodium 8-anilinyl-5- [4 - (3-sulfophenyl) azo-1-naphthyl] azo] naphthalene-1-sulfonate", choose a dry place to hide. Because of its fear of moisture, if it is in a humid environment, water vapor will invade it, and it may cause changes in its properties, and its efficacy or other uses will be harmed.
And it is better to avoid strong light. Photothermal interweaving can promote its chemical reactions, causing the components to decompose and deteriorate. Therefore, hiding in a dark room or using a shading device can reduce the disturbance of light and heat.
Furthermore, temperature is also necessary. Room temperature is appropriate, overheating will activate molecules and easily cause structural changes; undercooling may also change physical properties. If the temperature can be controlled between several degrees and more than 20 degrees, it is good.
Also, this thing may come into contact with other things, so it can be stored in one place to avoid mixing with foreign species, prevent interaction, and keep it pure and stable. Only in this way can it be hidden for a long time.
