Frequently Asked Questions

As a leading 4-Iodobiphenyl supplier, we deliver high-quality products across diverse grades to meet evolving needs, empowering global customers with safe, efficient, and compliant chemical solutions.

What are the main uses of 4-iodobiphenyl?

4 - Poisonous poison medicine, its main use is to eliminate harm, demonstration and rebellion.
Viewing "Tiangong Kaiwu", it is written: "Poisonous, like a peacock, purple-green hair, long-necked red beak, the head of the pit viper, the male name is lucky, the female name is yin harmonic, people eat and die immediately." Poisonous feathers drain, into the wine is poisonous wine, poisonous to the extreme.
The first word to eliminate the harm. In the ancient world, there were often evil insects and beasts as a disaster, and poisonous poison was occasionally used here. Or the giant python in the mountains and forests haunts, endangering the village, using poison to set its haunt, the python touches it and kills it, relieving the suffering of the people hanging upside down. However, the use of this is very small, and the poison is rare, and it is easy to cause harm to innocent creatures.
The second time is a demonstration. The princes are in dispute, or there are strong ministers who want to establish their prestige in the crowd. When holding a banquet, the wine of the enemy shifted advertising poison, and the poison was sent on the spot, and everyone was shocked to show their momentum and make everyone afraid. Although this is not the way of upright and bright, it is also a strategy to establish prestige in troubled times.
As for rebellion, it is the most evil use of poison and poison. In the court and above the court, those who compete for power and gain covet the position, and use poison to harm the monarch and kill his ministers. In the past, there were dizzy monarchs, who were addicted to their voices and ignored the government, and the powerful officials wanted to change the dynasty, so they used poison and poison in the imperial wine, causing the monarch to die Or there is a strife among the ministers, in order to get rid of political enemies, secretly poisoned and poisoned, causing their death, in order to consolidate their position.
The use of poison and poison, although there are small benefits in getting rid of harm, but demonstrations and rebellion have caused life to be ruined, chaotic, and bad society. Although it is an ancient poison, it is also enough for future generations to learn from it, be careful of the envoy of power, and avoid the meng of evil thoughts.

What are the synthesis methods of 4-iodobiphenyl?

There are many methods for synthesizing 4-benzylpyridine. Although the synthesis of such compounds is not directly mentioned in Tiangong Kaiwu, the chemical technology ideas of the ancients may be used for reference.
First, it can be prepared by nucleophilic substitution reaction of pyridine and benzyl halide in an alkaline environment. For example, pyridine is used as the base, benzyl chloride is used as the benzyl donor, and potassium carbonate is used as the base. In a suitable organic solvent such as acetonitrile, heat and stir. In this reaction process, the nitrogen atom of pyridine is nucleophilic, attacking the benzyl carbon of benzyl chloride, and the chloride ions leave to form 4-benzylpyridine. The reaction conditions are mild, the yield is quite high, and the benzyl halide is easy to obtain, and
Second, pyridine derivatives and reagents containing benzyl structures are synthesized by metal-catalyzed coupling reaction. For example, 4-halopyridine reacts with benzylboronic acid in a basic aqueous solution and an organic solvent mixed system under the action of a palladium catalyst such as tetra (triphenylphosphine) palladium. In this process, the palladium catalyst activates the carbon-halogen bond of halopyridine, transmetallizes with benzylboronic acid and eliminates it by reduction, and obtains the target product. Metal catalytic coupling has high precision and can build complex structures, but the catalyst is expensive, the reaction needs inert gas protection, and the operation is slightly complicated.
Third, the 4-benzylpyridine structure is established by multi-step reaction. First, pyridine is used as the starting material, and suitable functional groups are introduced through a specific reaction, and then reacted with benzyl-containing fragments. For example, pyridine is first nitrified to obtain 4-nitropyridine, reduced to 4-aminopyridine, and then reacted with benzylating reagents. Although this path has more steps, it can flexibly regulate the reaction. According to the raw materials and requirements, the route is designed, which is of great value for the synthesis of special substituents or complex structures.
The above methods have advantages and disadvantages. In actual synthesis, it is necessary to comprehensively consider factors such as raw material availability, cost, yield and purity requirements, and choose an appropriate method.

What are the physical properties of 4-iodobiphenyl?

Lead is soft and heavy, its color is dark, soft and easy to melt, and it has good electrical and thermal conductivity.
The density of lead is quite high, about 11.34 grams/cubic centimeter, which is heavier than ordinary metals such as iron and aluminum. Because of its soft nature, it can be cut with a knife and can be easily bent and deformed. When heated, lead is easy to melt, with a melting point of only 327.5 ° C, which is lower than that of most metals. This characteristic makes it useful in casting processes. In the past, it was often used as a casting tool.
Lead has good electrical and thermal conductivity. Although it is inferior to metals such as silver and copper, it is sufficient to conduct heat under certain circumstances. And lead has strong corrosion resistance, it is not easy to oxidize in the air, and it is difficult to react in contact with water. Because a dense lead oxide film can be formed on the surface to prevent further corrosion, lead pipes are often used to transport liquids.
Lead is toxic, which is one of its important physical properties. If the human body ingests lead, it will accumulate in the body, causing many health problems, such as damage to the nervous system, blood diseases, etc. Although the ancient people did not fully understand the toxicity mechanism of lead, they also knew its harm, so they rarely used lead utensils to contain food.
Lead exists in the form of lead sulfide, lead carbonate and other ores in nature, and pure lead can be extracted after smelting. In ancient times, it was mostly used for minting coins and making utensils, such as lead pots, lead candlesticks, etc., and was also used in construction to waterproof lead plates.

What are the precautions for storing and transporting 4-iodiphenyl?

If the land is humid, it is easy to be rotten by water, causing its products to suffer. And the place where it is hidden is suitable for good transportation, so that it can reduce moisture and condensation, and can also reduce the chemical reaction caused by the process, so as to protect the original characteristics of the product.
Furthermore, when it is in the process of storage, it is added according to its product quality and composition. The quality of different products has different uses, and the value is also different. If it is mixed and stacked, it is used to distinguish it, or the source and wave are caused, which is also unfavorable to the processing of the day.
In the case of heavy tools, especially heavy tools, it is appropriate to use heavy tools, such as road construction, large construction, etc., to ensure the balance of efficiency and cost. And on the way, strengthen the package to prevent it from being scattered in the bumps and shocks, and also to avoid the collision of foreign objects and the decline of the finished product.
In addition, the image should not be ignored. In case of bad weather such as rainstorms and blizzards, it is difficult to be affected or delayed, and it is easy to be affected. In high weather, it is necessary to pay attention to the dispersion to prevent some adverse reactions due to high temperature.
In order to maintain good quality in the storage process and lay the foundation for engineering and engineering, it is necessary to consider various factors, such as the environment, distribution management, tools, and image prevention.

What is the approximate market price of 4-iodobiphenyl?

At present, the price of sparrows in the city varies depending on the type, appearance, age and place of the bird.
Common sparrows are occasionally caught and sold in the market, and their price is low, or they can be purchased for only a few pennies. This sparrow is often found in the eaves and branches, and has lively habits, but there is nothing strange about it, so the price is not high.
