The synthesis method of 2% 2C5-difluoro-3-methylbenzylhydrazine does not directly correspond to the scope of "Tiangongkai", but it can be compared to the logic of the description of various processes in the book.
To synthesize this product, when the required raw materials and steps are stated. First, the selection of raw materials needs to be precise, such as "Tiangongkai", the creation needs to choose good materials. To synthesize 2% 2C5-difluoro-3-methylbenzylhydrazine, a compound containing fluorine, methyl, benzyl and other corresponding groups must be found as the starting material. The choice of fluorine source should consider the compatibility between its activity and reaction; the source of methyl and benzyl should also choose the one with good stability and reactivity. < Br >
Second, the reaction steps need to be ordered. Or first introduce fluorine atoms into a suitable substrate in a specific reaction, and this step should control the reaction conditions, such as temperature, pressure, and catalyst. "Tiangong Kaiji" records the conditions such as heavy heat in all processes, and the same is true. If the temperature is too high or side reactions occur frequently, if it is too low, the reaction will be slow or difficult to start. After introducing fluorine atoms, methyl and benzyl are connected in sequence through reaction. The stability and reactivity of the intermediate need to be considered between each step of the reaction, so that the synthesis path is coherent.
Third, separation and purification are also critical. After the product is generated, such as the refining of the product in "Tiangong Kaiwu", it is necessary to remove impurities by distillation, extraction, and recrystallization to obtain pure 2% 2C5-difluoro-3-methylbenzylhydrazine. During distillation, separate according to the difference in boiling point of each component; extract and adapt the solvent to separate the product and impurities into different phases; recrystallization uses the difference in solubility to obtain high-purity products.
Although the method of synthesis is not found in the original text of "Tiangong Kaiwu", the principles of creation, such as raw material selection, condition control, purification, etc., can be used as a reference for the synthesis of 2% 2C5-difluoro-3-methylbenzylhydrazine. According to the scientific method, the reaction of each step is advanced in an orderly manner, and the desired product is finally obtained.

2% 2C5-difluoro-3-ethylbenzylimidazole is an organic compound. Its physical properties are quite unique and are described in detail in ancient sayings.
This compound is either a solid state at room temperature. Looking at its shape, or a crystalline appearance, it is dense and has a certain luster, just like a natural crystal jade, radiant and considerable. Its melting point, boiling point and other key physical properties are closely related to the intermolecular forces. The atoms in the molecule are connected by specific valence bonds to form a stable structure, which gives it unique physical properties.
When it comes to the melting point, due to the restraint of intermolecular forces, a specific thermal energy is required to break the lattice structure and turn the solid state into a liquid state. Its boiling point is also restricted by the interaction between molecules. In order to vaporize it, it needs to supply enough energy to overcome the attractive force between molecules.
Furthermore, solubility is also an important physical property. In organic solvents, it may have a certain solubility. Because some groups in the molecular structure can form specific interactions with organic solvent molecules, such as van der Waals force, hydrogen bond, etc., it can be soluble in some organic solvents, just like fish get water, and it is fused infinitely. However, in water, its structure interacts weakly with water molecules, and the solubility may be very small, just like oil and water, which is difficult to blend.
Density is also one of its physical properties, depending on its molecular mass and molecular accumulation mode. The density of this compound is important in measuring its distribution and separation in mixtures.
In summary, the physical properties of 2% 2C5-difluoro-3-ethylbenzylimidazole are determined by its molecular structure and intermolecular interactions, and each property is interrelated to present the unique physical appearance of this compound.

2% 2C5-difluoro-3-methylbenzylchloroethazole should pay attention to the following things during storage and transportation:
First, the storage place should be selected as a cool, dry and well-ventilated place. This is because the substance may be quite sensitive to temperature and humidity, high temperature and humidity, or cause its properties to change, and even cause chemical instability, inducing decomposition and other adverse conditions. Therefore, it should be placed in a suitable temperature and humidity environment to ensure its quality stability.
Second, it must be stored separately from oxidants, acids, bases and other substances. Due to the chemical properties of 2% 2C5-difluoro-3-methylbenzylchloroethazole, if it is mixed with the above-mentioned substances, or has a violent chemical reaction, it will cause major dangers such as fire and explosion. It is stored in strict classification and is essential.
Third, the storage container must be well sealed. This substance may be volatile and poorly sealed, and it is easy to evaporate and escape. First, it will damage its content. Second, the volatile gas may be harmful to human health and may increase the risk of ignition and explosion. Therefore, sealed storage can avoid such hidden dangers.
Fourth, when transporting, it must be operated in accordance with relevant dangerous chemical transportation regulations. Transportation vehicles should be equipped with corresponding fire equipment and leakage emergency treatment equipment. Due to various conditions during transportation, fire equipment can be extinguished in case of fire, and leakage emergency treatment equipment can be dealt with in time when leakage occurs to minimize harm.
Fifth, transportation personnel must also undergo professional training, familiar with the characteristics and emergency treatment methods of 2% 2C5-difluoro-3-methylbenzyl chlorozole. In this way, in the face of emergencies, they can respond calmly and handle them properly to ensure the safety of the whole transportation process.

I have not heard of the exact market price of "2,5-difluoro-3-ethylbenzylchloropyridine" in the world. The price of these products is difficult to determine due to the difficulty of production, the differences in materials used, or the limitations of specific uses and needs.
The price of various things in the world often depends on multiple ends. If the preparation of this product requires rare materials, it is difficult to collect, or the process is exquisite and labor-intensive, its price will be high. And the wide range of uses and the rise and fall of demand are also factors for the change of price. If it is an essential agent for pharmaceutical research and development or chemical industry, if there are many applicants and few suppliers, the price will increase; on the contrary, if there is little application, little demand, and the price may tend to be flat.
And prices in the city often vary from time to place. In different domains, supply and demand are different, and merchants' policies are also special, resulting in different prices for the same thing. And the passage of time, the abundance of materials, and the new revolution in technology can all make prices rise and fall.
Therefore, if you want to know the actual price of "2,5-difluoro-3-ethylbenzylchloropyridine" in the market, you must visit the market of chemical materials, consult the franchised merchants, or refer to the platform and information of chemical trading, in order to obtain a more accurate number.
