What are the main uses of O-Aminobenzene Sulfonic Acid Phenyl Ester?
Phenyl o-aminobenzenesulfonate has a wide range of uses. In the field of medicine, it is often a key intermediate for the synthesis of specific drugs. With its unique chemical structure, it can participate in a series of chemical reactions to help build complex molecular structures with specific pharmacological activities, and then lay the foundation for the development of drugs for the treatment of various diseases.
In the dye industry, phenyl o-aminobenzenesulfonate also plays an important role. Due to its structural properties, it can be chemically modified and transformed to prepare dyes with bright colors and good stability. Such dyes are widely used in textiles, printing and dyeing and other industries, which can give fabrics brilliant colors and are not easy to fade.
Furthermore, in the field of organic synthesis, it is an important organic raw material, providing the possibility for the synthesis of other complex organic compounds.

What are the physical properties of O-Aminobenzene Sulfonic Acid Phenyl Ester
The physical properties of O-aminobenzenesulfonate phenyl ester are quite promising. Looking at its shape, at room temperature, it is mostly solid, white and pure, often like frost and snow, delicate and uniform, its particles are polymerized and slightly slippery to the touch.
When it comes to the melting point, the melting point is relatively high due to the force between molecules. A considerable amount of heat needs to be applied to disintegrate the lattice, and the molecules break free and gradually melt from the solid state into a liquid state. Its boiling point is also not low. To make it boil into a gaseous state, sufficient heat energy needs to be continuously input to overcome the many forces between molecules.
As for solubility, in water, its molecular structure contains both hydrophilic sulfonic acid groups and hydrophobic benzene rings and amino groups, so its solubility is limited. Although sulfonic acid groups can form hydrogen bonds with water molecules, the hydrophobicity of benzene rings and amino groups is hindered, making it only slightly soluble in water. However, in organic solvents such as ethanol and ether, due to the principle of similar miscibility, its solubility is greatly improved, and it can be better dispersed and dissolved.
Furthermore, its density is also one of the important physical properties. Compared with common light substances, its density is slightly higher, and it can be felt in similar containers. The difference in weight is due to its tight molecular composition and structure, and the relatively dense accumulation of atoms.
In addition, its appearance is often shiny, resembling a delicate jade, which is reflected in light and slightly flooded, giving it a rather textured appearance. This luster property is related to the reflection and refraction of molecules on light, and is also one of its unique physical properties.
What are the chemical properties of O-Aminobenzene Sulfonic Acid Phenyl Ester
Phenyl o-aminobenzenesulfonate, this compound has unique chemical properties. It contains amino groups and sulfonic acid phenyl ester groups, which are active in nature.
The amino group is basic and can form salts with acids. In case of inorganic strong acids, the lone pair of electrons of the amino nitrogen atom is easy to combine with the proton to form the corresponding ammonium salt. In organic synthesis, the amino group can participate in nucleophilic substitution, like reacting with halogenated hydrocarbons. The amino nitrogen attacks the carbon atom connected to the halogen atom in the halogenated hydrocarbon, and the halogen atom leaves to form a new carbon-nitrogen bond to synthesize nitrogen-containing organic compounds. In the sulfonate phenyl group, the benzene ring has certain stability and electron delocalization, while the sulfonate part, due to the strong electron absorption of oxygen in the sulfur-oxygen double bond, reduces the electron cloud density of sulfur atoms, and is vulnerable to nucleophilic attack. Nucleophilic substitution occurs, and the aromatic oxygen group leaves to form new organic sulfonic acid derivatives.
From the perspective of physical properties, o-aminobenzene sulfonate phenyl ester has a certain solubility in polar organic solvents such as ethanol and acetone, and its solubility in water is relatively small. And due to the interaction of hydrogen bonds and van der Waals forces between molecules, it has a specific melting point and boiling point, and its purity can be preliminarily identified by melting point determination.
In chemical reactions, it can participate in a variety of reaction pathways, such as under appropriate conditions, amino groups and sulfonate phenyl groups can simultaneously participate in the reaction to form complex cyclic or multi-functional compounds, which have potential application value in drug synthesis and materials science, or provide key intermediates for the preparation of new functional materials and bioactive molecules.
What is the production method of O-Aminobenzene Sulfonic Acid Phenyl Ester?
The method of preparing phenyl anthracylaminobenzene sulfonate is very complicated and requires rigorous steps. First, the preparation of anthracylaminobenzene and phenyl sulfonate as raw materials needs to be extremely pure, and impurities will hinder the reaction, resulting in low yield or by-products.
In an appropriate reaction vessel, according to the precise ratio of anthracylaminobenzene and phenyl sulfonate. This ratio is the key, related to the completion of the reaction and the purity of the product. Next, add a suitable catalyst. The choice of catalyst needs to be determined according to the reaction characteristics and conditions, which can promote the reaction speed, reduce the reaction temperature, and reduce consumption.
The reaction temperature and time are also important. The temperature is controlled in the precise range. If it is too low, the reaction will be slow, and if it is too long, it will also cause by-products to increase; if it is too high, it will cause the decomposition of raw materials or cause other side reactions. According to the reaction process and monitoring results, when the temperature is adjusted in a timely manner, the reaction will be smooth.
During the reaction, common monitoring methods, such as thin layer chromatography, gas chromatography or liquid chromatography, are used to observe the consumption of raw materials and the formation of products, indicating the progress of the reaction. After the reaction is completed, the separation and purification are carried out. High-purity phenyl o-aminobenzenesulfonate can be obtained by distillation, extraction, recrystallization, etc. except for unreacted raw materials, catalysts and by-products.
During distillation, the target is separated according to the difference in boiling Each step requires fine operation and adherence to chemical principles and specifications to obtain the best yield and purity of phenyl o-aminobenzenesulfonate.
