4-Fluoro (trifluoromethoxy) benzene is also an organic compound. Its physical properties are quite well researched.
First of all, its appearance, at room temperature, is mostly a colorless transparent liquid, clear and free of variegated colors, and it is fluid in appearance, like the agility of a spring.
When it comes to the boiling point, it is about 125-127 ° C. When the temperature rises gradually, the compound changes from liquid to gaseous state, and the interaction between molecules is destroyed by heat, breaking free and escaping in the air.
In terms of melting point, it is roughly around -27 ° C. Below this temperature, the molecular movement slows down and the attractive force between each other increases, and then solidifies into a solid state, and its shape is gradually determined.
As for the density, it is about 1.425g/cm ³, which is heavier than water. If the two are mixed, the substance will sink to the bottom of the water. The characteristics of its density are closely related to the structure of the molecule, the type and arrangement of atoms.
Solubility is also an important physical property. 4-Fluoro (trifluoromethoxy) benzene is insoluble in water, because its molecular structure is mostly hydrophobic groups, and the force between it and water molecules is weak. However, in organic solvents, such as ethanol, ether, etc., it has good solubility, because of the "similar miscibility" principle, it has a similar molecular structure with organic solvents, and the interaction is conducive to dissolution.
In addition, its vapor pressure also has a specific value at a certain temperature. The vapor pressure is related to the equilibrium state of the gas phase and the liquid phase, and has a significant impact on its volatility in different environments. In summary, these physical properties are of great significance in many fields such as chemical industry and medicine, as well as in the application, storage and transportation of this compound.

4-Fluoro (trifluoromethoxy) benzene is also an organic compound. It has unique chemical properties and has attracted much attention in the field of organic synthesis.
The physical properties of this compound are mostly colorless and transparent liquid at room temperature and pressure, and have a special odor. Its boiling point, melting point and other physical properties are related to the arrangement and interaction of atoms in the molecule. Because of the fluorine atom and trifluoromethoxy group, it has a certain stability.

Furthermore, the stability of this compound is derived from the reinforcement of molecular structures by fluorine atoms and trifluoromethoxy groups. However, under extreme conditions such as high temperature, strong acid, and strong base, its structure may change, triggering chemical reactions and generating other products.
Overall, 4-fluoro (trifluoromethoxy) benzene has broad application prospects in organic synthesis, medicine, materials and other fields due to its unique chemical properties. Researchers can follow its properties to develop more innovative applications.

The synthesis methods of 4-fluoro (trifluoromethoxy) benzene are quite diverse, and the following are common routes.
First, 4-fluorophenol is used as the starting material. First, it is co-placed with potassium carbonate and other bases in a suitable solvent, such as N, N-dimethylformamide (DMF), and then trifluoromethyl sulfonyl fluoride (CF 🥰 SO 🥰 F) is added. In this reaction process, the base can capture the hydrogen of the hydroxyl group of 4-fluorophenol to form phenoxy anions. Its nucleophilicity is quite strong, and it can undergo nucleophilic substitution reaction with trifluoromethyl sulfonyl fluoride, thereby obtaining 4-fluoro (trifluoromethoxy) benzene. The key to this approach lies in the control of the reaction conditions, such as temperature, the amount of alkali, etc., which will affect the reaction yield.
Second, starting from 4-fluoroaniline. First, it is diazotized, and sodium nitrite and hydrochloric acid are often used as reagents to form diazonium salts at low temperatures. Next, the diazoyl salts are mixed with trifluoromethoxy reagents, such as metal salts of trifluoromethanol (such as potassium trifluoromethanol). The diazoyl salts are extremely reactive and will undergo a displacement reaction with the trifluoromethoxy reagent, resulting in the final formation of the target product 4-fluoro (trifluoromethoxy) benzene. In this process, it is very important to control the temperature of the diazotization reaction. If the temperature is too high, the diazonium salt is easy to decompose and the yield is reduced.
Third, 4-fluorobrobenzene is used as the substrate. Under the catalysis of palladium catalysts, such as tetrakis (triphenylphosphine) palladium (Pd (PPh)), react with trifluoromethoxy negative ion sources, such as trifluoromethoxy potassium, in a suitable solvent (such as toluene). This is a typical palladium-catalyzed coupling reaction. The palladium catalyst activates the carbon-halogen bond, making it easier to react with trifluoromethoxy negative ions. However, factors such as catalyst dosage, reaction time, and reaction temperature need to be finely adjusted to achieve good yield and selectivity.
The above synthesis methods each have their own advantages and disadvantages. In practical application, it is necessary to consider the availability of raw materials, cost, difficulty in controlling reaction conditions, and many other factors, and carefully select the appropriate method.

I look at the price range of 4 - Fluoro (Trifluoromethoxy) Benzene in the market. However, the price of this product often changes due to multiple reasons, and it is difficult to hide it in one word.
Its price is related to the supply and demand of raw materials. If the raw materials are abundant, the price is flat; if the raw materials are scarce, the price will rise. And the production process is complicated. The process is complicated, the cost must be high, and the price will follow.
The trend of supply and demand in the market also affects the price. If there are many people in demand, if the supply is insufficient, the price will rise; if the supply exceeds the demand, the price will drop. There is also a difference in quality, and the price of high quality is often higher than that of ordinary people.
To confirm the price, you can visit the chemical raw material trading market, consult merchants, or get a more accurate price. Or check the chemical information platform to observe the recent price trend. However, according to my knowledge, the price per kilogram may be between hundreds and thousands of yuan, which is only a rough estimate, and the actual price shall be subject to market conditions.
