What is the chemical structure of Biphenyl-4-Sulfonate?
Biphenyl-4-Sulfonate is biphenyl-4-sulfonate, and its chemical structure is as follows. Biphenyl is connected by two benzene rings through a single bond to form a planar conjugated system. At position 4 of one of the benzene rings, a sulfonate (-SO 🥰) is connected. In the sulfonate, the sulfur atom is connected to three oxygen atoms in different chemical bonds, one of the oxygen atoms is connected to the sulfur atom in a double bond, and the other two oxygen atoms are connected to the sulfur atom in a single bond, and these two oxygen atoms are negatively charged, so that the whole sulfonate takes on the properties of an anion. This structure gives the biphenyl-4-sulfonate a certain water solubility and chemical activity. In different chemical reactions and material applications, the conjugated structure of biphenyl provides certain stability and electron transfer characteristics, while sulfonate can participate in reactions such as ion exchange and combine with other cations to form corresponding salts. These characteristics make biphenyl-4-sulfonate unique in many fields such as surfactants and material synthesis.

What are the physical properties of Biphenyl-4-Sulfonate?
Biphenyl-4-sulfonate is a class of organic compounds with unique physical properties. Its properties are mostly solid at room temperature, or powdery, or crystalline, with a fine and uniform texture. The color of this compound is often white or nearly white, with pure color and few variegated colors.
Looking at its solubility, it has a certain solubility in water. The sulfonate group is hydrophilic and can interact with water molecules to form hydrated ions, causing it to be partially soluble in the aqueous phase. However, in organic solvents, the solubility varies depending on the type of solvent. For example, polar organic solvents may have good interactions with biphenyl-4-sulfonate molecules and good solubility; non-polar organic solvents have poor solubility due to weak interaction with polar sulfonate groups.
When it comes to melting point, biphenyl-4-sulfonate usually has a higher melting point. This is due to the interaction between molecules such as ionic bonds, hydrogen bonds and van der Waals forces, which requires higher energy to overcome, so that the solid state can be converted into a liquid state. The higher melting point also makes it stable at room temperature and pressure.
As for the density, compared with common organic solvents, its density is slightly higher. Due to the presence of benzene rings and sulfonate groups in the molecular structure, the molecular weight is increased, and the molecular arrangement is relatively tight, so the density is increased. These physical properties are of great significance in many fields such as chemical synthesis, material preparation and industrial applications, related to their separation, purification and practical application effects.
Biphenyl-4-Sulfonate is widely used in which areas
Biphenyl-4-sulfonate is widely used in many fields. In the field of industry, it is often used as a surfactant. This substance has a unique molecular structure, which can significantly reduce the surface tension on the interface.

And because of its good emulsifying properties, in the emulsion polymerization process, the monomers can be stably dispersed, helping to synthesize high-quality polymer materials, such as the preparation of high-quality coatings, adhesives, etc.
In the field of daily chemicals, biphenyl-4-sulfonate also has outstanding performance. In detergents, it can enhance the decontamination ability and effectively remove oil stains and stains. Because it can reduce the surface tension of water, make water more easily penetrate into the fabric fibers, separate and disperse dirt, so as to achieve the purpose of efficient cleaning. In personal care products, such as shampoo and shower gel, appropriate addition can improve the foam performance of the product, make it rich and stable, and improve the user's experience.
Furthermore, in the field of biomedicine, it can also be seen. It may be used as a modifier for drug carriers, improving the solubility and stability of drugs by virtue of its own characteristics, and helping drugs to better exert their therapeutic effects. At the same time, in some bioanalytical experiments, it may be used to adjust the interface properties of the reaction system and promote the identification and reaction of biomolecules, which is of great significance for accurate detection and diagnosis. In summary, biphenyl-4-sulfonate is indispensable in many fields such as industry, daily chemicals and biomedicine, and is widely used.
What is Biphenyl-4-Sulfonate synthesis method?
The method of making biphenyl-4-sulfonate has been used in ancient times, and it is described in detail below.
First take biphenyl, which is an organic aromatic compound with stable structure and is the foundation for making biphenyl-4-sulfonate. Place the biphenyl in a reactor, which needs to be clean and dry to prevent impurities from disturbing it.
Next, add an appropriate amount of fuming sulfuric acid. Fuming sulfuric acid has strong oxidizing and sulfonating properties and is a key reagent for this reaction. When administering the drug, it needs to be slowly poured in and stirred to make the reaction system evenly mixed to prevent local overheating or uneven reaction.
When reacting, the temperature should be controlled to the point. Initially, it is advisable to start at a low temperature, about 50 to 60 degrees Celsius. At this stage, the reaction is mild, allowing the sulfonated group to be gradually introduced into the biphenyl molecule. Then, it is gradually heated to 100 to 120 degrees Celsius to promote the complete reaction. This heating process should not be rushed to ensure a smooth reaction.
After the reaction is completed, when the system cools, it can be poured into ice water. Ice hydrolysis of this mixture can precipitate biphenyl-4-sulfonate. After filtering, the solid is collected. The collected solid still contains impurities and needs to be purified by recrystallization. Take an appropriate solvent, such as ethanol-water mixture, dissolve the solid, heat to dissolve, then cool and crystallize, and filter again to obtain pure biphenyl-4-sulfonate. The whole process requires fine operation and proper control of conditions to obtain good products.
