1-Ethoxy-4- [4- (4-ethylcyclohexyl) phenyl] -2,3-difluorobenzene has different properties. Its color is often clear and transparent. If the jade liquid is formed at the beginning, it shines brightly under the light, and the visibility is very good.
When it comes to the melting point, it is about [X] ° C, just like the condensation of water, and the shape is determined at a specific temperature. The boiling point is at [X] ° C. It rises when heated, like the change of clouds, from liquid phase to gas phase.
Its solubility is like a duck to water in organic solvents. It can be fused with aromatic hydrocarbons, such as benzene and toluene, and can also be miscible in halogenated hydrocarbons, such as dichloromethane and chloroform. It is like water and emulsion, but in water it is like oil floating on water. It is distinct and difficult to dissolve.
This substance has a slightly lighter density than water, such as wood floating in water, placed on water, and floats leisurely. And it has good stability. Under normal temperature and humidity, it is like a gentleman who is not alarmed by changes. The structure is quiet and not easy to change. However, when encountering strong acids and alkalis, or baking at high temperature, it is like an enemy, and the structure is easily damaged, and the nature changes accordingly.
Its refractive index also has characteristics, and the light passes through it, such as the lost path, and the direction is slightly changed, presenting a unique optical phenomenon, which may be useful in the optical field. These are all 1-ethoxy-4- [4- (4-ethylcyclohexyl) phenyl] -2,3-difluorobenzene. The physical characteristics are different, and it is essential for its use and for its researchers.

The chemical synthesis of 1-ethoxy-4- [4- (4-ethylcyclohexyl) phenyl] -2,3-difluorobenzene is a complex and delicate process.
The choice of starting materials is crucial. It is often based on a benzene derivative with a specific structure. This derivative needs to contain functional groups that can be modified by subsequent reactions, such as halogen atoms, hydroxyl groups, etc., to facilitate the introduction of ethoxy, fluorine atoms and ethylcyclohexyl-containing phenyl structures. The introduction of ethoxy groups
is often synthesized by Williamson ether. The corresponding phenolic compounds and halogenated ethane are heated in an alkaline environment, such as the presence of strong bases such as potassium carbonate and sodium hydroxide, in an appropriate solvent, such as dimethylformamide (DMF) and acetonitrile. The base can capture the hydrogen of the phenolic hydroxyl group and generate phenoxy negative ions. Its nucleophilicity is strong, and it can attack the carbon atoms of halogenated ethane and undergo nucleophilic substitution reactions, thereby forming ethoxy groups.
The introduction of fluorine atoms is commonly used in nucleophilic fluorination reactions. With benzene derivatives containing appropriate leaving groups, such as compounds containing halogen atoms (chlorine, bromine, etc.), and nucleophilic fluorine sources, such as potassium fluoride, tetrabutylammonium fluoride, etc., in aprotic polar solvents, such as dimethyl sulfoxide (DMSO), heat and stir. The fluorine anion of the nucleophilic fluorine source attacks the halogen atom on the benzene ring, and the halogen atom leaves to realize the introduction of the fluorine atom.
As for the connection of the 4- (4-ethylcyclohexyl) phenyl structure, the coupling reaction is often catalyzed by palladium. For example, in the Suzuki coupling reaction, the 4- (4-ethylcyclohexyl) benzene derivative containing borate ester or boric acid and the benzene derivative containing halogen atom are heated and refluxed in a suitable solvent, such as toluene-ethanol-water mixed solvent, in the presence of a palladium catalyst, such as tetra (triphenylphosphine) palladium (0), and a base, such as sodium carbonate. The palladium catalyst can promote the formation of carbon-carbon bonds between two aryl groups to achieve the construction of the target structure.
During the reaction process, the reaction conditions, such as temperature, reaction time, and material ratio, need to be carefully adjusted. If the temperature is too high, or the side reaction increases, the purity of the product will decrease; if the temperature is too low, the reaction rate will be slow and the yield will be poor. The reaction time also needs to be precisely controlled. If it is too short, the reaction will be incomplete, and if it is too long, it will cause the product to decompose. The proper allocation of material proportions can ensure the smooth progress of each reaction step, and avoid excessive waste of a certain material or affecting the purity of the product. After the reaction, it needs to be separated and purified by extraction, column chromatography, etc., to obtain high-purity 1-ethoxy-4- [4- (4-ethylcyclohexyl) phenyl] -2,3-difluorobenzene.

I don't know the price range of 1 - Ethoxy - 4 - [4 - (4 - Ethylcyclohexyl) phenyl] -2,3 - Difluoro - Benzene in the market. The price of this chemical substance often changes for many reasons. Such as the price of raw materials, the difficulty of production, the situation of supply and demand, and the quality of quality are all related to it.
When it comes to raw materials, the price of raw materials fluctuates, changing with their own supply and demand and market conditions. If the raw materials for making this substance are rare and expensive, the cost of this chemical will also increase, and the price will increase.
The difficulty of production is also the key. If the preparation method is complicated, requires special equipment, strict conditions and superb skills, and consumes a lot of manpower, material resources and time, the price will be high.
The supply and demand situation also affects its price. If the market demand for this product is strong and the supply is limited, the price will easily rise; conversely, if the supply exceeds the demand, the price may drop.
The quality difference also affects the price. High purity, high quality, the price is often higher than the ordinary quality.
To know the exact price range, you should consult chemical reagent suppliers, chemical product trading platforms, or the industry. However, due to the rapid changes in the market, the obtained price is only a temporary reference, and it is difficult to have a constant price.
