2-Amino-3, what are the physical properties of 5-diiodo-4-methyl-pyridine
2 - amino - 3,5 - diiodo - 4 - methyl - pyridine is an organic compound. Its physical properties are as follows:
Viewed, this compound is often solid. Due to the existence of various forces between molecules, such as van der Waals forces and hydrogen bonds, the molecules are closely arranged, so they are in a solid state.
When talking about the melting point, due to the large atomic weight of iodine atoms in the molecular structure and the strong intermolecular forces, the melting point is relatively high. However, the exact value varies depending on the experimental conditions and purity, and needs to be accurately determined by the experiment.
In terms of boiling point, in view of the strong intermolecular force, in order to make it boil, more energy needs to be supplied to overcome this force, so the boiling point is also quite high.
In terms of solubility, the compound has poor solubility in water. Due to its limited molecular polarity, although the amino group contains a certain polarity, the iodine atom and the methyl group enhance the non-polarity of the molecule, and the interaction with polar solvents such as water is weak. However, in some organic solvents, such as ethanol and dichloromethane, the solubility is slightly better, because these organic solvents can form moderate forces with the molecules of the compound, such as van der Waals forces, to help it dissolve.
And its density is also affected by the molecular structure and atomic weight. The atomic weight of the iodine atom is large, which makes the molecular density relatively large. But the specific density also needs to be accurately measured experimentally.
In summary, the physical properties of 2-amino-3,5-diiodo-4-methyl-pyridine are determined by their own structure. In practical application and research, it is necessary to properly handle and use it according to its physical properties.
What are the synthesis methods of 2-amino-3, 5-diiodo-4-methyl-pyridine
The methods for synthesizing 2-amino-3,5-diiodine-4-methylpyridine are described in ancient books, or there are various methods. One method is to first take a suitable pyridine derivative as the base. The structure of this derivative must be similar to the structure of the target product, and some substituents may already exist at specific positions on the pyridine ring, such as 4-methylpyridine.
Then, it is aminated. It is often reacted with ammonia or an amino-containing reagent under suitable conditions. This condition may involve the choice of temperature, pressure and catalyst. The temperature may be controlled at tens of degrees Celsius to 100 degrees Celsius, and the pressure may be between normal pressure and several times normal pressure. Catalyst or choose metal salts, such as copper salts, help amino groups smoothly connect to the designated position of the pyridine ring to obtain amino-containing pyridine derivatives.
Then, perform the steps of iodization. Choose an iodine source, such as iodine elemental substance with a suitable oxidant, or use an iodizing agent. In a specific reaction system, make iodine atoms connect to the 3rd and 5th positions of the pyridine ring. The solvent, pH and other factors of the reaction system are affected. Solvent or choose an organic solvent, such as dichloromethane, N, N-dimethylformamide, etc. The pH can be controlled by a buffer to ensure the smooth progress of the reaction, so that 2-amino-3,5-diiodine-4-methylpyridine can be obtained.
There are other methods, or iodine atoms are introduced into the pyridine ring first, followed by amination, and the order changes. However, the reaction conditions need to be carefully regulated according to the reaction characteristics of each step to achieve the purpose of synthesis.
2-Amino-3, 5-diiodo-4-methyl-pyridine What are the precautions in storage and transportation?
2-Amino-3,5-diiodo-4-methyl-pyridine is an organic compound, and there are indeed many precautions to be taken when storing and transporting.
First of all, this compound should be placed in a cool, dry and well-ventilated place. Because the cool environment can avoid changes in its properties caused by excessive temperature, the dry environment can prevent deliquescence caused by moisture or adverse reactions related to water, and good ventilation can timely disperse volatile gases that may accumulate, and keep the storage environment safe.
Furthermore, be sure to keep away from fire and heat sources. Because of its flammability, in case of open flames, hot topics may cause combustion or even explosion, endangering the safety of the surrounding. And to be stored separately from oxidants, acids, etc., because of its active chemical properties, contact with these substances is likely to cause violent chemical reactions, resulting in danger.
As for transportation, the compound needs to be properly packaged. Packaging materials should be able to prevent leakage and collision, to ensure that it is not damaged during transportation bumps, and the substance does not leak. During transportation, temperature should also be strictly controlled, and it should not be placed in an overheated or overcooled environment, so as not to affect its chemical stability.
Transport vehicles should also be equipped with corresponding fire equipment and leakage emergency treatment equipment. In the event of a leak on the way, emergency measures can be taken quickly to reduce the hazard. The escort personnel also need to be professionally trained, familiar with the characteristics of this compound and emergency response methods, and remain vigilant throughout the transportation to ensure the safety of transportation. In this way, it is necessary to ensure that 2-amino-3,5-diiodo-4-methyl-pyridine is safe in storage and transportation.
What is the market price of 2-amino-3, 5-diiodo-4-methyl-pyridine?
I haven't heard of the market price of "2-amino-3,5-diiodo-4-methyl-pyridine". However, if you want to estimate its price, you can think about it from multiple angles.
Let's talk about the preparation of this thing first. If the preparation method is complicated, the materials used are rare, the steps are lengthy, and the exquisite skills and harsh conditions are required, such as alchemy, the temperature and ingredients are difficult to control, the price will be high. The preparation requires expensive starting materials, or the reaction requires rare catalysts, and the recovery is not easy. If gold is used as a guide, its cost will be high, and the price will follow.
Second look at its demand. If it is in the research and development of medicine, it is necessary to make special drugs, just like the elixir that helps the world, and the price is also higher. In the field of material science, if it is a material that casts extraordinary properties, such as the key material for refining sharp weapons, its price should not be low.
And on its purity. For high purity, such as fine gold and jade, impurities are rare, and the more difficult it is to prepare, the price must be higher than for low purity.
And market competition is also the main reason. If there are many people who produce this, such as a hundred schools of thought contending, the supply exceeds the demand, the price may drop; if only a few companies can make it, like a unique secret book, the price may rise steadily.
In the end, because I don't know the details, it is difficult to determine the exact price of the market. If you want to know the details, you should consult the merchants specializing in chemical reagents, or explore the markets of chemical transactions, in order to obtain a more accurate price.
