Its color may be white to light yellow powder, which is caused by the arrangement of atoms and the distribution of electron clouds in the molecular structure. This appearance characteristic is easy to identify and distinguish, and it can be distinguished at a glance in practical operation and research.
Solubility is also a key property. The substance can exhibit a certain solubility in water. Due to the presence of sulfonic acid groups, this group is hydrophilic and can form hydrogen bonds with water molecules, so it can be partially dissolved in water. However, the hydrophobicity of phenyl and indole rings limits their solubility. In organic solvents, such as ethanol and acetone, its solubility may be better than that of water. The polarity of ethanol and acetone is moderate, and it is adapted to the intermolecular force of 2-phenylindole-5-sulfonic acid, so that the compound can be well dispersed in it.
Melting point is also an important physical property. After determination, its melting point is in a specific temperature range, which depends on the strength of the intermolecular force.

Knowing the melting point is of great significance in purifying and identifying the substance, so that its purity can be judged.
In addition, the density of this compound is also a property. Although its exact density needs to be accurately measured, the density value reflects the mass of the substance per unit volume. When mixed with other substances, the density difference can be used for separation and purification.
In summary, the physical properties of 2-phenylindole-5-sulfonic acid, such as appearance, solubility, melting point, density, etc., are of indispensable significance for its application and research in chemical industry, scientific research and other fields.

2-Phenylindole-5-Sulfonic Acid is chemically stable?

2-Phenylindole-5-sulfonic acid, the chemical properties of this substance are really related to its structural characteristics. According to the chemical theory contained in previous books, those containing sulfonic acid groups are mostly acidic. This 2-phenylindole-5-sulfonic acid, sulfonic acid group (-SO-H) can ionize hydrogen ions, so its aqueous solution is acidic and can neutralize with alkali substances.
And looking at its phenyl and indole groups, phenyl groups are aromatic and stable in structure, which can affect the electron cloud distribution of molecules and cause their chemical activities to be different. Indole groups are also nitrogen-containing heterocycles, giving molecules unique electronic properties. The two are connected, so that the whole molecule exhibits a specific chemical behavior in the reaction.
As for the stability, the basic body of sulfonic acid is relatively stable, but under extreme conditions, such as strong acid, strong base and high temperature, the sulfonic acid group may change, such as hydrolysis and other reactions. The conjugated system composed of phenyl and indole groups, although it enhances the stability to a certain extent, may also undergo oxidation and other reactions to cause structural changes.
Overall, 2-phenylindole-5-sulfonic acid has a certain stability under conventional conditions, but in special chemical environments, its chemical properties may undergo various changes. It is necessary to investigate in detail according to specific situations to determine its exact chemical behavior and stability.

What is the synthesis method of 2-Phenylindole-5-Sulfonic Acid?

To prepare 2-phenylindole-5-sulfonic acid, you can follow the following ancient method.
First take an appropriate amount of indole, in a suitable reactor, add an appropriate amount of organic solvent, such as dichloromethane or N, N-dimethylformamide, stir well, so that the indole is fully dissolved. This is the basis for the reaction.
Subsequently, the reaction system is cooled to a specific low temperature range, generally about 0 ° C to -10 ° C, to ensure a smooth reaction. Slowly add carefully prepared phenylating reagents, such as phenyl halide, and continue to stir during the dropwise addition process to allow the reactants to fully contact. Add it dropwise, gradually raise it to room temperature, maintain stirring, and make the phenylation reaction fully proceed. During this process, close attention should be paid to the reaction process, which can be monitored by thin-layer chromatography and other means. When the raw material indole is significantly reduced and the product is initially present, the reaction is moderate.
When the phenylation reaction reaches the expected level, adjust the reaction system to another suitable temperature range, generally 50 ° C to 80 ° C. Slowly add an appropriate amount of sulfonating reagents, such as concentrated sulfuric acid or fuming sulfuric acid. Be careful when adding, because the sulfonation reaction is violent and prone to heat generation. Add it, and continue to stir for a few times to make the sulfonation reaction complete. During the period, it is also necessary to monitor by analytical means. The reaction can only be stopped when the amount of 2-phenylindole-5-sulfonic acid formed reaches a considerable degree.
At the end of the reaction, the reaction mixture is poured into a large amount of ice water, the reaction is stopped by quenching, and the product is precipitated. Next, the precipitated solid is collected by filtration, and washed with an appropriate amount of cold water to remove impurities. The obtained crude product can be purified by recrystallization. A suitable solvent, such as ethanol-water mixed solvent, is heated to dissolve the crude product, filtered while hot, the filtrate is cooled to crystallize, and the crystals are filtered again. After drying, a relatively pure 2-phenylindole-5-sulfonic acid can be obtained.

2-Phenylindole-5-Sulfonic the price of Acid in the market

What you are asking is the price of 2-phenylindole-5-sulfonic acid in the market. However, the price of this product is not included in "Tiangong Kaiwu". At that time, chemical synthesis was not as developed as it is today, and such fine organic compounds may not be available in the market.
Today is different from the past. Chemical technology has advanced, and the preparation of 2-phenylindole-5-sulfonic acid is available. The price is determined by many factors. First, the cost of raw materials. To prepare this product, the price of raw materials used is different.
