4- - α -（ 1-methylethyl) - (α S) -naphthalene acetic acid. From the structural point of view, the naphthalene ring structure endows the molecule with certain rigidity and stability. The naphthalene ring is a fused aromatic hydrocarbon with a conjugated system, which makes the electron cloud distribution special and affects the molecular physical and chemical properties.
In terms of physical properties, it is usually a solid state due to the interaction of van der Waals forces and hydrogen bonds between molecules. Its melting point and boiling point are affected by intermolecular forces. Molecular polarity determines solubility in different solvents, containing carboxyl groups and other polar groups, so that it has a certain solubility in polar solvents such as alcohol and water (to a certain extent), but less solubility in non-polar solvents.
Chemical properties, carboxyl groups are acidic and can neutralize with bases to form corresponding carboxylic salts. This reaction is commonly used in organic synthesis and drug preparation, which can change the solubility and stability of molecules. In addition, hydrogen atoms on the naphthalene ring can undergo substitution reactions, such as halogenation, nitrification, etc. Due to the electron cloud density distribution of the naphthalene ring, the reaction check point is selective. The (1 -methylethyl) group on the side chain can also participate in the reaction, such as oxidation, substitution, etc.
α-chiral center endows it with optical activity, which is of great significance in asymmetric synthesis and drug development. Different enantiomers interact with biological targets or are different, with different biological activities and pharmacological effects.
This compound is often used as a plant growth regulator in the agricultural field. It can regulate plant growth and development, such as promoting rooting, flowering, fruiting, etc., by affecting hormone balance and signal transduction in plants. In organic synthesis, it is an important intermediate and can construct complex organic molecular structures through a series of reactions.

In the production process, it is necessary to keep in mind all the general points to ensure the quality and yield of the product.
First, the selection of raw materials is important. Therefore, the general raw materials must be of good purity and free of impurities. If the raw material contains impurities, it may cause side reactions during the reaction process, resulting in a decrease in the purity of the product, and affect the reaction process. As far as this specific compound is concerned, it involves various groups, donors, such as those containing (1-methylethyl) structures. The test agent must be strictly controlled for purity and quality.
Second, the reaction conditions also need to be precisely controlled. The temperature is, in which, the key is closed. Therefore, the reaction can proceed smoothly within a specific temperature range. If the temperature is too high, it may lead to an overreaction and produce by-products. If the temperature is too low, the reaction rate may slow down, and it may even make the reaction difficult to start. In addition to temperature, pressure is also not allowed. Some reactions can improve reaction efficiency and selectivity under specific pressures. Moreover, the pH value of the reaction system needs to be adjusted and controlled appropriately in order to provide a good chemical environment for the reaction.
Furthermore, the use of catalysts requires careful use. The catalyst can significantly change the reaction rate, but if the choice is not appropriate, it may cause adverse effects. According to this, the mechanism, mechanism and characteristics of the reaction, the appropriate catalyst must be selected and the dosage should be precisely controlled. In excess, the catalyst may cause side reactions, and if the dosage is insufficient, it is difficult to achieve the catalytic effect of the predicted period.
In addition, the reaction equipment is also required. The reactor needs to have good corrosion resistance to prevent the reaction of the product or the product from occurring with the equipment and affecting the quality of the product. At the same time, the mixing performance of the equipment should also be good to ensure that the reaction can be fully contacted and improve the reaction efficiency.
In short, in the production process of 4 + - - α -（ 1 -methylethyl) - (α S) -sulfuric acid, raw materials, reaction conditions, catalysts, and reaction equipment, etc., all aspects need to be strictly controlled to successfully obtain high-quality products.

I have heard your inquiry about the market price of 4 + - - α - （ 1 -methethyl) - (α S) -benzoic acid. However, the price of such chemicals often changes for a variety of reasons, and it is difficult to give an exact value directly.
First, the price of raw materials is the key. If the price of basic raw materials used in the synthesis of benzoic acid, such as toluene and methanol, fluctuates, the cost of benzoic acid will also change. If the supply of toluene is tight and the price rises, the production cost of benzoic acid will increase, and its market price may also increase.
Second, the production process has a great impact. Advanced and efficient processes can reduce energy consumption, productivity, and cost, and the price may decrease. However, if the process is outdated, the loss is large, the yield is low, and the cost is high, the price will be expensive.
Third, market supply and demand determine the price. If many chemical companies have strong demand for benzoic acid, but the supply of production enterprises is limited, the supply is in short supply, and the price will rise. On the contrary, if the market demand is weak and the supply is sufficient, the price will decline.
Fourth, regional factors cannot be ignored. In different places, the price of benzoic acid is also different due to differences in transportation costs and market competition. In places where production enterprises are concentrated, the competition is intense, and the price may be low; in places where transportation is inconvenient and the supply is small, the price may be high.
Overall, the market price of benzoic acid ranges from tens of yuan to hundreds of yuan per kilogram, but this is only a rough estimate. The actual price depends on the specific time, place and market conditions.

(The following is answered in ancient classical Chinese style)
The storage conditions of
< 4 + -Gan - α - （ 1 -methylethyl) - (α S) -threonine are crucial to the preservation of its quality. This is because of the nature of the object, which is easily disturbed by various external factors. If it is not stored properly, it may lose its original characteristics, or even deteriorate and be useless.
The temperature and humidity of the first environment for its storage. It should be placed in a cool and dry place, protected from direct sunlight and heat, and protected from humid erosion. If it is placed in a warm place, it may cause its components to decompose and volatilize, which will damage its efficacy; if it is in a humid environment, it is prone to mildew and rot, causing material corruption. Therefore, the most suitable place is at room temperature and dry, about 15 to 25 degrees Celsius, and the humidity should be controlled at 40 to 60%.
Furthermore, pay attention to its isolation from foreign objects. Cover the object or chemically react with surrounding substances, causing quality to change. Therefore, it needs to be stored in a sealed container to avoid contact with air, moisture and other chemicals. And the equipment used should also be made of suitable materials and do not interact with the substance to ensure its purity.
In addition, light is also an important factor. Strong light irradiation, or lead to the change of photolysis of the substance, causing its properties to change. Therefore, the hiding place should be dark and less light to protect its stability.
In short, if you want to hide 4 + -Gan - α - （ 1 -methylethyl) - (α S) -threonine, you must pay attention to temperature and humidity, prevent foreign object intrusion, and avoid strong light exposure. In this way, you can preserve it for a long time without losing its effectiveness.
