Sodium + 4 - [[4- (4 - Hydroxy - 2 - Methyl - Phenyl) Azophenyl] Amino] - 3 - Nitro - Benzenesulfonate, this substance is called 4- [4- (4 - Hydroxy - 2 - Methyl - Phenyl) Azophenyl] Amino] - 3 - Nitrobenzene sulfonate sodium.
Its physical properties are generally as follows:
This substance may be in a solid state, and its color is often bright, mostly orange-yellow, red, etc. Because of its azo-containing structure, this structure often gives the substance a bright color. In terms of solubility, due to the sodium sulfonate group, it has a certain solubility in water and can form a uniform solution.
Melting point, boiling point and other thermal properties are also important. However, due to the complex molecular structure, containing benzene rings, nitro groups, hydroxyl groups and many other groups, the interaction is complicated, resulting in high melting point and boiling point. The presence of nitro groups increases the intermolecular force, and the conjugate system of benzene rings also stabilizes its structure and enhances its thermal stability.
In terms of density, it is determined by the molecular composition and accumulation method. Due to the relatively large mass of groups such as benzene rings and sulfonic acid groups, their density may be greater than that of common organic solvents. Compared with the density of water, it depends on the specific structure and substituents.
The physical properties of this substance are of great significance in its application. Its solubility and color properties may make it useful in the field of dyes and pigments; good thermal stability, or can be used in industrial processes with strict temperature requirements.

The preparation of this product requires a specific method. First, when the required raw materials are prepared. 4- (4-hydroxy-2-methyl-phenyl) azoaniline, 3-nitro-benzenesulfonic acid and its sodium salts are all key raw materials, and their purity and quality need to be ensured.
Then, in a suitable reaction vessel, 4 - (4-hydroxy-2-methyl-phenyl) azoaniline is mixed into a suitable solvent. This solvent should be able to dissolve the reactants well and have no adverse effects on the reaction. Organic solvents such as dimethyl sulfoxide or N, N-dimethylformamide can be selected as needed.
Then, under stirring, slowly add 3-nitro-benzenesulfonate sodium salt. The stirring speed should be moderate, so that the two are fully mixed. At the same time, the temperature and time of the reaction should be precisely controlled. The temperature may need to be maintained in a specific range, such as between 50 and 80 degrees Celsius, and the time depends on the reaction process, or several hours or even ten hours. During the reaction, closely monitor the reaction status, and use thin-layer chromatography and other methods to observe the degree of reaction.
After the reaction is completed, proceed to the steps of separation and purification. Or by means of filtration, extraction, column chromatography, etc., to remove impurities and obtain a pure product Sodium + 4 - [[4 - (4 - Hydroxy - 2 - Methyl - Phenyl) Azophenyl] Amino] - 3 - Nitro - Benzenesulfonate. Each step requires fine operation to obtain high-quality products.

Sodium + 4 - [[4 - (4 - Hydroxy - 2 - Methyl - Phenyl) Azophenyl] Amino] - 3 - Nitro - Benzenesulfonate, is a chemical whose safety is related to many aspects.
On the toxic side, or potentially toxic, if the human body inadvertently contacts, inhales or ingests, or causes damage to the body. Take contact as an example, or irritate the skin and eyes, causing redness, swelling and pain; inhaling its dust, or affecting the respiratory tract, causing cough, asthma, or even damage lung function; if ingested inadvertently, or damage the digestive system, causing nausea, vomiting, abdominal pain and other problems.
From the perspective of environmental impact, if this substance enters the environment, it may pose a threat to the ecosystem. In water bodies, it may affect the survival and reproduction of aquatic organisms, destroy the ecological balance of water; in soil, or affect the activities of soil microorganisms, which in turn affect plant growth.
