2-Methoxy-4-nitro-aniline-5-sulfonic acid, sodium salt, is one of the organic compounds. Its physical properties are quite critical, and it plays a significant role in the chemical industry and other fields.
The appearance of this compound is often in a solid state, and the specific color may vary due to factors such as purity, or it is a white-like to yellow solid. In terms of solubility, it can show certain solubility in water. This is due to the presence of sulfonate sodium salt in its molecular structure, which is hydrophilic, so that this compound has a certain solubility in water and can form a uniform dispersion system. However, in organic solvents such as ethanol and ether, the solubility may be quite different from that in water, and factors such as the polarity of the organic solvent and the intermolecular forces will affect its dissolution.
Furthermore, the melting point is also an important physical property. Accurate melting point data is of great significance for identifying the compound and controlling its purity. When the compound is heated to a specific temperature, the transition from solid to liquid state occurs, which is the melting point. By accurately measuring the melting point, its purity can be determined. If it contains impurities, the melting point may decrease and the melting range becomes wider.
In addition, the density of the compound also has certain characteristics. Its density reflects the mass per unit volume of the substance. In chemical production, for the measurement and mixing of materials, density data can provide important reference and help to accurately control the production process.
To sum up, the physical properties of 2-methoxy-4-nitro-aniline-5-sulfonic acid, sodium salt appearance, solubility, melting point and density are of indispensable significance in chemical synthesis, product quality control and many other aspects.

2-Methoxy-4-nitro-aniline-5-sulfonic acid, sodium salt, this is an organic compound. Its physical properties are usually solid, mostly powdery or crystalline, and the color may vary from white to yellow.
When it comes to solubility, it may have a certain solubility in water, because sodium salts often have good water solubility, this property makes it easier to disperse and participate in reactions in aqueous solution systems or applications.
In terms of chemical stability, the structures of methoxy, nitro, sulfonic acid and sodium salts in the molecular structure all affect its stability. Nitro is a strong electron-absorbing group, which can reduce the electron cloud density of the benzene ring and enhance the oxidation of the molecule. Under specific conditions, it may participate in the oxidation-reduction reaction. Sodium sulfonate salt imparts ionic properties to the compound and increases its stability in polar solvents. However, the compound may be sensitive to heat, light and certain chemical reagents. At high temperatures, it may cause reactions such as intramolecular chemical bond breaking and rearrangement; light may also promote photochemical reactions to occur, causing molecular structure changes.
In the field of organic synthesis, this compound is often used as an intermediate. The diverse functional groups in its structure provide rich possibilities for subsequent reactions. For example, nitro can be reduced into amino groups, expanding the molecular reaction path, which can be used to construct complex organic molecules containing various functional groups. Sulfonate sodium salts can participate in ion exchange reactions or be used to introduce specific hydrophilic groups to target molecules.
However, due to its chemical properties, conditions should be paid attention to when storing and using. It should be stored in a cool, dry and dark place to avoid deterioration due to environmental factors and ensure its chemical stability, which is conducive to subsequent applications.

2-Methoxy-4-nitro-5-aminobenzenesulfonic acid, sodium salt is a very important raw material in organic synthesis. During the synthesis process, many key precautions cannot be ignored.
The first to bear the brunt is the quality of the raw materials. It is necessary to ensure that the raw materials such as 2-methoxy-4-nitroaniline and sulfonating reagents have high purity, and the mixing of impurities can easily lead to clumps of side reactions, which greatly reduces the purity of the product. Therefore, when purchasing raw materials, it is necessary to strictly control the quality and carefully verify the relevant indicators.
The precise control of the reaction conditions is also a top priority. In terms of temperature, if the sulfonation reaction temperature is too high, it is easy to cause excessive sulfonation and generate unnecessary sulfonated products; if the temperature is too low, the reaction rate will be slow, it will take a long time and the yield will not reach the expected. Generally speaking, the appropriate temperature range needs to be set and precisely adjusted according to the specific reaction. The reaction time also needs to be accurately controlled. If it is too short, the reaction will not be fully functional, and if it is too long, side reactions may breed. Furthermore, pH has a great impact on the reaction process. Some steps need to be carried out under a specific pH environment, otherwise it may affect the structure and purity of the product.
The selection and maintenance of reaction equipment should not be underestimated. Because the reaction may involve corrosive sulfonating reagents, the material of the equipment must be corrosion-resistant, and the equipment must be clean and free of impurities before the reaction, so as not to affect the reaction. At the same time, a good stirring device is indispensable, which can promote the full contact of the reactants and ensure the uniform progress of the reaction.
Safety protection measures need to be strictly implemented. Many raw materials and reagents are toxic, corrosive or irritating, and complete protective equipment must be worn during operation, such as protective clothing, gloves, goggles, etc. And the reaction should be carried out in a well-ventilated environment, and harmful gases should be discharged in time to prevent accidents such as poisoning or explosion.
Product separation and purification should also be treated with caution. After the reaction, according to the characteristics of the product, appropriate methods should be selected for separation, such as crystallization, extraction, distillation, etc. The purification process is designed to maximize the removal of impurities and improve the purity of the product. It requires multiple washes, drying and testing until it meets Quality Standards. Only in this way can the smooth synthesis of 2-methoxy-4-nitro-5-aminobenzenesulfonic acid and sodium salt be guaranteed to obtain high-quality products.

The price range of the sodium salt of 2-methoxy-4-nitro-5-aminobenzenesulfonic acid is difficult to determine with certainty. The price is influenced by many factors, such as the cost of raw materials, the preparation process, the supply and demand of the market, and even the business strategy of the merchant.
In the past, the cost of raw materials has a huge impact on the price. If the methoxy, nitro, aminobenzenesulfonic acid and other raw materials required for the preparation of this sodium salt fluctuate due to changes in origin, season, and output, the final price of sodium salt will also fluctuate. For example, at a certain time and place, methoxy raw materials are scarce, resulting in a significant increase in the cost, and the price of this sodium salt also rises.
The preparation process is also the key. Sophisticated and efficient processes can reduce costs, and prices may tend to be easy; if the process is complicated and the loss is too much, the cost will be high, and the price will be high. For example, the newly created process can greatly improve the output rate and reduce impurities, which is different from traditional process products when priced in the market.
The state of market supply and demand also affects its price. If a certain period, the industry demand for 2-methoxy-4-nitro-5-aminobenzene sulfonic acid sodium salt increases sharply, but the supply is limited, its price will rise; on the contrary, if the supply exceeds the demand, the merchant may sell it for promotion, or there may be price cuts.
As for the business strategy of merchants, there are different. Or seek small profits but quick turnover, and compete for market share at a low price; or rely on product quality and brand advantages to obtain higher profits, and the price is also high. Therefore, considering all factors, in order to determine its price range, it is necessary to carefully observe the current market conditions, which is difficult to generalize.
