In the field of analytical chemistry, it is often used as an acid-base indicator. Due to its unique structure, its color changes significantly and easily observable in different acid and alkali environments. When the degree of acid and alkali in a solution changes, the distribution of electron clouds in the molecular structure of the substance changes accordingly, resulting in changes in the wavelength of absorbed light, showing different colors. With this property, analytical chemists can accurately determine the acid and alkali state of a solution by observing its color change. It is widely used in various acid-base titration experiments to help accurately determine the content and properties of substances.
In some industrial production processes, it can also be used as a surfactant. With both hydrophilic sulfonic acid groups and hydrophobic benzene rings and azo structures in the molecule, it can reduce the surface tension of liquids and promote better mixing and dispersion between different phases. In processes such as emulsion polymerization, monomers can be uniformly dispersed in the medium, which helps to form a stable emulsion system and improve product quality and performance.
In addition, in some scientific research experiments, it can be used as a marker or tracer. Using its unique structure and optical properties, researchers can track its behavior and distribution in the reaction system or in the living body with the help of specific instruments, providing key information for in-depth exploration of reaction mechanism, substance transportation and metabolism in the living body.

What is the preparation method of Sodium 3- (P-Anilinophenylazo) Benzenesulphonate?
The preparation of 3- (p-anilinyl benzenesulfonate) sodium benzenesulfonate is quite complicated and requires detailed steps and procedures.
First of all, the raw materials need to be prepared. Both p-anilinyl benzenesulfonate and sodium hydroxide are key. The p-anilinyl benzenesulfonate needs to be of considerable purity to ensure the quality of the product. Sodium hydroxide should also be pure to avoid impurities affecting the reaction.
Then, in a suitable reaction vessel, pour the p-anilinyl benzenesulfonate slowly into an appropriate amount of sodium hydroxide solution. This process requires careful operation, paying attention to the ratio of the two, usually according to a precise stoichiometric ratio, so that the reaction is sufficient without excess raw materials remaining.
After mixing, moderately heat the reaction system. Heating temperature and duration need to be precisely controlled. If the temperature is too high, it may cause the product to decompose; if the temperature is too low, the reaction will be slow and difficult to achieve expectations. Generally speaking, it is maintained in a specific temperature range, such as between [X] ° C and [X] ° C, for a long time, so that the reaction can be smoothly advanced.
During the reaction, constant stirring is required to promote uniform mixing of raw materials, accelerate the reaction rate, and make the reaction more complete. The stirring rate should also be moderate. If it is too fast or the system is unstable, if it is too slow, the mixing will not be good.
After the reaction is completed, cool down for a while. Then, separate and purify. The product can be separated from the reaction mixture by filtration, crystallization, etc. Filtration requires filter paper or membrane with suitable pore size to ensure effective separation of the product and impurities. When crystallizing, control the cooling rate and solvent dosage to obtain a high-purity crystal product.
After separation and purification, the product needs to be dried to remove the moisture contained in it and make the product reach a stable state. The drying temperature and duration also need to be properly considered to avoid damage to the product. In this way, 3- (p-aniline phenylazo) sodium benzenesulfonate can be prepared.
What are the precautions for using Sodium 3- (P-Anilinophenylazo) Benzenesulphonate?
Sodium 3- (P - Anilinophenylazo) Benzenesulphonate, when using, many matters need to be paid attention to.
First, the properties of this substance must be carefully observed. It has a specific chemical structure and characteristics, and may react differently in different environments. If the pH, temperature, humidity and other conditions of the system change, its chemical activity or morphology may also change. Therefore, before use, it is necessary to have a clear understanding of its stability and reaction tendency under the corresponding conditions.
Second, safety protection must not be ignored. During operation, appropriate protective measures must be taken. Because it may be irritating, if it accidentally touches the skin and eyes, rinse with plenty of water as soon as possible, and seek medical attention according to the specific situation. When operating, it should also be carried out in a well-ventilated place to prevent inhalation of its dust or volatiles and damage to the respiratory tract.
Third, accurate control of the dosage is crucial. The amount of its dosage is directly related to the use effect. If the dosage is too small, it may be difficult to achieve the expected effect; if the dosage is too large, it will not only cause waste, but also cause negative effects. For example, in some chemical reactions, excessive addition or increase of side reactions will affect the purity and yield of the product.
Fourth, storage conditions should also be paid attention to. It should be stored in a dry, cool and ventilated place, away from fire, heat and strong oxidants. Improper storage or deterioration will affect subsequent use.
In conclusion, when using Sodium 3- (P - Anilinophenylazo) Benzenesulphonate, the above items should be treated with caution to ensure that the use process is safe, efficient, and achieves the intended purpose.
