1% 2C1% 27-binaphthalene, 4-sulfonic acid, in the form of white to light yellow crystalline powder. Its solubility is quite special, soluble in water, this property makes it possible to apply in many aqueous systems, such as some chemical reactions that need to be carried out in aqueous solution, which can be participated in by its water solubility. In organic solvents, such as ethanol, acetone, etc., it also has a certain solubility, but the solubility varies depending on the type of solvent. This property is important for the separation and purification of products during organic synthesis, or for the construction of specific reaction environments.
When it comes to melting point, 1% 2C1% 27-binaphthalene, 4-sulfonic acid has a relatively high melting point, which indicates that its intermolecular forces are strong and its structure is relatively stable. The characteristics of high melting point make it difficult for the substance to undergo phase transition in high temperature environments and maintain a solid-state structure, which becomes an important consideration in some industrial processes or storage conditions with high temperature requirements.
In terms of stability, under normal conditions, 1% 2C1% 27-binaphthalene, 4-sulfonic acid is quite stable and does not easily react with common substances in the air such as oxygen and carbon dioxide. However, in strong acid and strong alkali environments, its structure may be damaged and its chemical properties may change. Therefore, when storing and using the substance, it is necessary to pay full attention to the acidity and alkalinity of the environment to avoid deterioration of the substance due to improper environment, which will affect its normal use efficiency.

The chemical properties of 1% 2C1% 27-binaphthalene, 4-carboxyl group are quite complicated, let me go through them one by one.
This compound has a unique spatial structure, and its naphthalene ring is connected, resulting in certain rigidity and chirality of the molecule. Chirality is one of its important characteristics and has a wide range of uses in the field of asymmetric synthesis. Because the chiral environment can selectively affect the reaction substrate, it is often used as a chiral catalyst or ligand to assist in the synthesis of compounds with specific configurations.
Its 4-carboxyl group part has the general nature of carboxyl groups. It is acidic and can neutralize with bases to form corresponding carboxylate.

Furthermore, the typical reaction of aromatic hydrocarbons can occur in the naphthalene ring part. Such as electrophilic substitution reaction, because the naphthalene ring has a high electron cloud density, it is vulnerable to electrophilic attack. Common electrophilic substitution check points have α and β positions. Under different reaction conditions, the substitution check point will be preferred. Can occur halogenation reaction, under the action of a specific catalyst, can introduce halogen atoms; can also occur nitrification reaction, sulfonation reaction, etc., the introduction of the corresponding functional groups.

To prepare 1,1 '-binaphthalene and 4-ether, the method is as follows:
First take the naphthalene as the base, and use appropriate reagents and conditions to make it undergo a specific reaction. Metal catalysts are often used to activate the specific position of the naphthalene. If palladium and other metal complexes are used as catalysts, the direction and selectivity of the reaction can be guided.
In the reaction system, the temperature, solvent and the ratio of reactants are finely regulated. If the temperature is too high or too low, it may affect the rate of the reaction and the purity of the product. A suitable solvent can provide a suitable environment for the reaction to promote the smooth progress of the reaction.
At the beginning of the reaction, the raw materials are carefully prepared to ensure their purity and quality. Mix naphthalene with other reagents in the appropriate proportion, in the reaction vessel, under the protection of inert gas, start the reaction. The function of inert gas is to prevent unnecessary side reactions between the reactants and the air and ensure the stability of the reaction system.
During the reaction process, pay close attention to the progress of the reaction by means of thin layer chromatography (TLC) and other monitoring means. When the reaction reaches the desired level, terminate the reaction by an appropriate method. Or cool down, or add a specific stopping agent to stop the reaction in time to avoid unnecessary by-products from overreaction.
Then, the reaction products are separated and purified. Column chromatography, recrystallization and other means are commonly used. Column chromatography can achieve effective separation according to the difference in the partition coefficient of the product and the impurity between the stationary phase and the mobile phase. Recrystallization takes advantage of the difference in the solubility of the product and the impurity in a specific solvent with temperature to achieve the purpose of purification.
After the above steps, careful operation and careful regulation, a relatively pure 1,1 '-binaphthalene and 4-ether product can be obtained. The key to preparation lies in the precise grasp of each reaction process and strict control of raw materials, reagents, conditions and other factors.

1% 2C1% 27-binaphthalene, 4-carboxyl This substance is in the market, and its price varies according to its quality, quantity and seller. In today's market, its price ranges from tens of gold to hundreds of gold per gram. If you want it to be inexpensive and good, you should carefully observe and compare it among suppliers.
Husband 1% 2C1% 27-binaphthalene, 4-carboxyl group, is widely used in chemical research, pharmaceutical preparation and other fields. The method of its preparation, or naphthalene-based, is obtained through various steps of transformation. However, the difficulty of its production, the materials and workmanship required, are also related to the price.
And its purity, the price is also an important factor. The higher the purity, the higher the price. If it is used for high-precision research or pharmaceutical production, you must ask for high-purity products, and the price will be higher. And if it is used for general chemical testing or research, those with a slightly lower purity can also be used, and the price will be cheaper.
The amount of quantity is also related to the price. If the purchase quantity is low, the supplier often gives a discount, and the price may be reduced. Therefore, if you want to know the exact price, you should consult with the supplier in detail, and ask for the exact price according to the quality and quantity you need.
