Orescein 4 5 6 7 Tetrachloro 2 4 5 7 Tetraiodo Disodium Salt

This is tetrachlorotetraiodine fluorescein disodium, commonly known as erythrosine, which has a wide range of uses. In the food industry, it is often used as a edible red pigment, which is added to candies, beverages, pastries, etc., to make its color attractive and increase appetite. Such as sugar coating on the outer layer of candies and in beverage liquids, it can be seen, adding brilliant color to food. In the field of pharmaceuticals, it can be used as a drug colorant to make the appearance of drugs more recognizable, making it easier for patients to distinguish between different drugs, especially in children's medications. Bright colors can reduce children's resistance to medication. In the cosmetics industry, it is also an important coloring raw material, used in lipstick, eyeshadow and other makeup products, giving it colorful colors and meeting consumers' diverse In some scientific research experiments and analytical tests, due to its special optical properties, it can be used as a fluorescent indicator or tracer to help researchers observe and analyze specific substances or reaction processes. In short, tetrachlorotetraiodofluorescein disodium plays an important role in many fields, enriching life and assisting scientific research progress.

This substance is named 4,5,6,7-tetrachloro-2 ', 4', 5 ', 7' -tetraiodofluorescein disodium salt, which has the following chemical properties:
First, in terms of solubility, the sodium salt usually exhibits good solubility in water, which makes it easy to integrate into aqueous solution systems. It is widely used in many experiments and industrial processes using water as a medium, such as some biological dyeing experiments, which need to be formulated into aqueous solutions for dyeing biological samples.
Second, in terms of color characteristics, the substance exhibits a specific color, which originates from the conjugated system and halogen atom substituents present in the molecular structure. The conjugated system can absorb specific wavelengths of visible light, causing it to exhibit bright colors. It is often used as a dye or indicator to indicate specific chemical or biological processes by color changes.
Third, the level of chemical stability, under normal conditions, it is relatively stable. However, in extreme environments such as strong acids, strong bases or strong oxidants, the molecular structure may be damaged. For example, when encountering strong oxidants, the iodine atoms or chlorine atoms in the molecule may be oxidized, changing their chemical properties and color characteristics.
Fourth, in terms of spectral characteristics, because of its specific molecular structure, it has unique absorption and emission characteristics in the spectrum. It has a characteristic absorption peak in the ultraviolet-visible absorption spectrum, which can be used for qualitative and quantitative analysis to determine its content in the sample by measuring the absorbance of a specific wavelength.
Fifth, in terms of biological activity, the substance is often used as a fluorescent probe or dye in the biological field. Due to the molecular structure containing multiple halogen atoms, or affecting its interaction with biological macromolecules, such as binding with proteins and nucleic acids, the structure and function of biological macromolecules are studied by means of fluorescent properties.

Fu tetrachlorotetraiodine fluorescein disodium salt is a chemical substance. When storing, there are several points to pay attention to.
First, pay attention to the temperature and humidity of the environment. This substance should be stored in a cool and dry place, away from high temperature and humidity. If it is in a high temperature environment, it may cause its chemical properties to change, such as accelerated decomposition or deterioration; in case of moisture, it is easy to absorb moisture and agglomerate, which affects its quality and use.
Second, pay attention to isolating the air. Oxygen, water vapor and other components in the air may react chemically with the substance, causing it to fail. Therefore, when storing, it should be contained in a well-sealed container to prevent air from invading.
Third, avoiding light is also the key. Light, especially strong light, or lead to luminescent chemical reactions, causing changes in the structure of tetrachlorotetraiodofluorescein disodium salt. It should be placed in a dark container such as a brown bottle and stored in a dark place.
Fourth, keep away from incompatible substances. This substance may react with certain acids, bases, oxidizing agents, reducing agents, etc. When storing, be sure to keep it separate from such substances to prevent accidental chemical reactions and ensure its stability and safety.
Furthermore, the place of storage should be clearly marked. Indicate the name of the substance, specifications, storage date and other key information for easy management and access, and can keep abreast of its storage period and use it reasonably within the valid period. Therefore, the tetrachlorotetraiodofluorescein disodium salt must be properly preserved to stabilize its properties and be available when needed.

Ore red, 4, 5, 6, 7 - tetrachloro - 2 ', 4', 5 ', 7' - tetrachloro -, disodium salt, the production process is as follows:
First, prepare refined raw materials. Select high-quality and pure basic materials, and after multiple screening and purification methods, remove impurities and ensure high purity of raw materials. This is the foundation for producing high-quality products.
Then, in a special reactor, according to the precise ratio, put the reactants. Control the reaction temperature, pressure and duration to fully react each substance. In the meantime, a catalyst may be added to promote the efficient progress of the reaction. The temperature must be stable. If it is too high, the reaction will be too fast, resulting in side reactions. If it is too low, the reaction will be slow and time-consuming.
After the reaction is completed, the mixed product is obtained. After separation and purification, such as filtration, extraction, crystallization, etc., the target product is analyzed. Filtration removes insoluble impurities, extraction enriches the product, and crystallizes to obtain pure crystals.
Subsequently, the product needs to be dried. Choose a suitable drying method, such as vacuum drying, hot air drying, etc., to remove moisture and ensure the stability and purity of the product.
At the end, after strict quality inspection, various indicators of the product, such as purity, impurity content, color, etc., are all in line with the standard. The finished product can be packaged and put into storage for sale. This process is interconnected, and negligence in any aspect can affect product quality.

I have a question today about the market price range of "Orescein, 4, 5, 6, 7-tetrachloro-2 ', 4', 5 ', 7' -tetrachloro-iodine-disodium salt". However, it is not easy to understand this price.
Prices in the city often change for many reasons. First, the number of places where this medicine is produced varies, and there are many places of origin and abundant output, so the price may decrease; if the place of origin is rare and the output is small, the price will be high. Second, the number of people who want to buy this product is also the main reason. Those who need it are in a tide, and the supply is in short supply, and the price will rise; those who ask for it are few, and the supply exceeds the demand, and the price will fall. Third, the difficulty of production and the level of cost all affect the price. If the production process is complicated, the materials used are rare, the cost is high, and the price is not cheap; if the process is simple, the raw materials are easy to obtain, the cost is low and the price is also low.
And the market conditions are changing rapidly, and the past records are difficult to prove. Or you can consult the merchants of various pharmaceutical shops, who are often involved in the transaction of this product, and their price may be known. Or check the relevant business books and market records, or you can get one or two clues. However, if you want to know the exact price range, you need to explore it in detail. After repeated visits, you can get a more accurate number. Now it is difficult for me to determine the range of its price.
