1,2,3-Tribromo-5-chlorobenzene is an organohalogenated aromatic hydrocarbon compound. Its chemical properties are very interesting. Although it is not directly described in ancient scientific and technological texts such as Tiangong Kaiwu, its approximate properties can also be obtained in classical Chinese.
In this compound, the presence of bromine and chlorine atoms gives it unique reactivity. Halogen atoms have strong electronegativity, which changes the electron cloud density distribution of the benzene ring. Therefore, in the electrophilic substitution reaction, its reactivity is different from that of benzene. Due to the blunt action of bromine and chlorine, it is more difficult for electrophilic reagents to attack the benzene ring, and the reaction conditions may be more severe.
And because it contains multiple halogen atoms, the substitution reaction of halogen atoms can occur under specific conditions. When encountering nucleophilic reagents, halogen atoms can be replaced by nucleophilic groups, and this process may require suitable solvents and catalysts.
Furthermore, the physical properties of the compound are also related to halogen atoms. Its melting point, boiling point or due to the increase of halogen atoms and the increase of intermolecular force. And because it is a halogenated aromatic hydrocarbon, its solubility in organic solvents may be better than that of water, which can be known from the principle of similar phase solubility. The chemical properties of 1,2,3-tribromo-5-chlorobenzene are determined by the halogen atoms in its structure. They exhibit different properties from ordinary aromatics in various reactions and may have specific uses in fields such as organic synthesis.

1%2C2%2C3-%E4%B8%89%E6%B0%9F-5-%E7%A2%98%E8%8B%AF%E7%9A%84%E5%B8%82%E5%9C%BA%E4%BB%B7%E6%A0%BC%E4%B8%8D%E5%8F%AF%E4%B8%80%E8%87%B4%E8%80%85%E4%B9%9F, the cover is made by many factors because of its price. First, the quality of medicinal materials is essential. Those who are of high quality, such as those who are collected in good conditions and processed according to ancient methods, must have higher prices than regular products. Second, the difference in season also affects its price. During the peak growing season, the yield is abundant and the price is flat; however, when it is scarce, the price rises. Third, the market supply and demand state, the price is very huge. If there are many people who want it, and there are few people who supply it, the price will increase; on the contrary, if the supply exceeds the demand, the price may drop.
According to current market conditions, the price of this medicinal material is about [X] yuan to [X] yuan per catty. However, this is only an approximate number. The market conditions vary from place to place, or due to geographical distances and trading rules, the price fluctuates. And the market conditions are unstable, and the price changes from time to time. Or due to natural disasters or man-made disasters, its output will drop sharply, and the price will surge; or due to new techniques, the output will increase greatly, and the price may also drop.
Therefore, if you want to know its accurate market price, you need to study the real-time market conditions in various places and observe the changes in the market.

This medicine should be placed in a cool and dry place, avoid direct sunlight. Its nature likes shade, if exposed to the hot sun, it is afraid that the drug power will dissipate and lose its effectiveness. And the storage place should be clean, away from filth and odor, in order to prevent it from being invaded by turbid gas and causing drug mutation.
The storage environment temperature also needs to be paid attention to, not too high, too high will easily cause changes in the quality of the medicine, affecting the efficacy; nor too low, too cold for fear of condensation damage.
Furthermore, this medicine should be sealed and stored to prevent air from entering. In the air, there are many impurities. If the medicine is in contact with the air for a long time, it is easy to be damp and moldy, or react with various substances in the air, changing its original medicinal properties.
It needs to be placed separately from other drugs and should not be mixed in one place. All kinds of drugs have different flavors. If they are mixed with each other, they may cause odors and drug properties to interfere, which will cause the drug to lose its original effect.
The person who keeps this medicine should also be cautious, familiar with the need for storage, and check it regularly to prevent changes in the quality of the medicine and not know it. Make sure that when using the medicine, the medicine is pure and can achieve the expected effect.
