1-(4-Bromophenyl)imidazole

What is the main use of 1 - (4 - Poria) Decoction? This is the key to the prescription of medicine. Although "Tiangong Kaiwu" is not a classic book that focuses on medicine, there are also lessons to be learned from the combing of traditional knowledge. In ancient classical Chinese, 4 - Poria Decoction, its main use, is mostly related to the conditioning of human health. Poria is a commonly used medicinal material, which has the effect of promoting water infiltration, strengthening the spleen and calming the heart. In the decoction, or by its power to benefit water, to get rid of dampness evil. The evil of water and dampness is easy to trap the spleen and stomach, hinder the qi machine, and cause many discomforts. Using Poria to infiltrate water and dampness can make the evil of dampness come out from the urine, and the qi machine of the spleen and stomach is smooth. And the power of Poria cocos to strengthen the spleen can help the spleen and stomach to transport and transform. The spleen and stomach are the foundation of the day after tomorrow, the source of qi and blood biochemistry, and the spleen and stomach are healthy, so that the qi and blood are sufficient and the body is healthy. Furthermore, its calming effect can calm the mind and nourish the mind. If people are restless, they are prone to irritability and insomnia. Poria in this soup recipe may have the effect of calming the mind. The combination of soup prescriptions must comprehensively consider the characteristics of various medicinal materials to achieve the purpose of synergy. Or in combination with other medicines, enhance the power of water, or complement each other, strengthen the power of strengthening the spleen, or jointly exert the effect of calming the heart, with the power of the whole party, regulate the balance of yin and yang of the human body, and restore the body to a healthy state. This is roughly the main use of 1 - (4 - Poria) Decoction.

The physical properties of 1- (4-boryl) pyridine are as follows:
Its external properties are often solid, which is due to the molecular action force, which causes it to maintain a specific aggregation under normal conditions. In terms of melting, it is more or less fixed, and it is roughly fixed to a certain extent. This melting property depends on the density of the molecule and the weak interaction of the molecule. In its molecular structure, the boron-based pyridine phase is different, and this special combination method affects the molecular force and determines the melting.
In terms of solubility, 1- (4-boryl) pyridine has a certain solubility in partial solubility. For example, in the soluble solution, it can be partially dissolved due to the principle of similar miscibility. In the non-soluble solution, the solubility is poor. This poor solubility is due to the unique properties of its molecules, and the existence of boron groups makes the molecular integrity stable.
Density is also one of its important physical properties, and its density is low in molecular weight and molecular stacking. Due to the particularity of the molecule, its density can be determined by high precision.
In addition, 1- (4-boryl) pyridine has a certain quality. Among them, pyridine is aromatic and can provide a certain degree of stability. Boron-based molecules have some activity, but under certain conditions, the whole molecule can still maintain phase stability. However, in case of specialization such as oxidation or protozonium, the molecular structure may be altered, which also reflects its qualitative phase.
Therefore, the physical properties of 1- (4-boryl) pyridine are determined by its molecular structure, and under different environments, some properties may be subtly changed.

The chemical synthesis of 1- (4-hydroxybenzyl) pyridine is a delicate technique, and it is described in detail today.
To obtain this compound, a specific organic compound is often used as the starting material. Pyridine derivatives with suitable substituents can be taken first, and the properties of the pyridine ring in the structure are stable and have a specific reactivity check point. On this basis, the reaction can be carried out.
Under suitable reaction conditions, such as selecting an appropriate solvent to create the desired environment for the reaction. Among organic solvents, dichloromethane, N, N-dimethylformamide, etc. are commonly used, which can fully dissolve the reactants and exist stably, which is conducive to the progress of the reaction.
At the same time, the control of temperature is crucial. Reactions at different stages require either low temperatures to inhibit the occurrence of side reactions, or heating to accelerate the reaction rate. Usually at low temperatures, the temperature of the system is maintained at about 0 ° C in an ice bath; when heated, the temperature is adjusted between tens of degrees Celsius and more than 100 degrees Celsius according to the reaction process.
One of the keys is the introduction of hydroxybenzyl. Halogenated benzyl compounds can be used to undergo nucleophilic substitution reactions with pyridine derivatives under alkaline conditions. Basic reagents such as potassium carbonate and sodium hydroxide can promote the departure of halogen atoms in halobenzyl, so that the benzyl part is connected to the pyridine ring, and then the basic skeleton of 1- (4-hydroxybenzyl) pyridine is preliminarily constructed.
However, the product may need to be further purified at this time, and column chromatography is often used. The target product is separated and purified by silica gel as the stationary phase, and the pure 1- (4-hydroxybenzyl) pyridine can be obtained according to the difference in the adsorption and desorption ability of the product and impurities in the mobile phase (such as the mixture of petroleum ether and ethyl acetate in different proportions). This synthesis method requires fine operation and precise control of reaction conditions in order to effectively and efficiently achieve the preparation of the target compound.

In the city of Guanfu, the price of (4-bromobenzyl) bromine often changes for various reasons. This substance is widely used in the chemical industry, and its price is also valued by everyone.
The range of the price cap is difficult to determine. The root cause is the abundance of raw materials. If bromide and benzyl raw materials are easily available and abundant, the price may tend to be flat, the price per catty, or between tens of dollars and hundreds of dollars. However, if raw materials are scarce and there are many seekers, the price will rise, or even more than hundreds of dollars per catty.
Furthermore, the complexity of the process is also related to the price. If the method of preparing (4-bromobenzyl) bromine is simple and efficient, and the production is easy, its price will not be too high; on the contrary, if the process is complicated, many steps are required, and consumables are laborious, the price will also rise.
And the supply and demand of the market is the master of the price. When the demand is strong, although merchants want to increase their production, or due to various conditions, they cannot meet the needs of the market, and the price will rise; if the demand is sluggish and the inventory is overstocked, merchants will reduce their prices to attract customers in order to sell their goods quickly.
In summary, the market price of (4-bromobenzyl) bromine fluctuates between tens of dollars per catty and hundreds of dollars per catty. To obtain the exact number, it is necessary to carefully consider the raw materials, processes, supply and demand conditions at the time.
