4- (4-phenylphenyl) iodobenzene is one of the organic compounds. Its physical properties are worth exploring.
First of all, its appearance, at room temperature, is often white to light yellow crystalline powder. This appearance characteristic is quite critical when identifying and preliminarily recognizing the compound. Its powder is fine in texture and can be seen clearly. However, if you want to accurately identify it, you need to use other methods.
Second discussion on melting point. The melting point of 4 - (4-phenylphenyl) iodobenzene is about 115-119 degrees Celsius. Determination of melting point is an important means to confirm the purity of the compound. When the compound is pure, the melting point range is narrow; if impurities are mixed in, the melting point may be offset and the range becomes wider.
Let's talk about solubility again. This compound exhibits certain solubility properties in organic solvents. Common organic solvents, such as dichloromethane, chloroform, toluene, etc., can dissolve 4- (4-phenylphenyl) iodobenzene. This solubility property is very useful in the reaction operation of organic synthesis. Because many organic reactions need to be carried out in solution, a suitable solvent can ensure that the reactants are fully contacted, thereby promoting the smooth occurrence of the reaction. However, in water, its solubility is very small, because the molecular structure of the compound has a large proportion of hydrophobic phenyl groups and iodophenyl groups, making it difficult to dissolve in the polar aqueous phase.
In addition, the physical properties of 4- (4-phenylphenyl) iodobenzene, such as density and boiling point, are also of great significance for its research and application.

In summary, the physical properties of 4- (4-phenylphenyl) iodobenzene, such as appearance, melting point, solubility, etc., are the cornerstone of in-depth understanding and application of this compound, and play an indispensable role in many fields of organic chemistry.

There are many ways to synthesize 4- (4-phenylphenyl) iodobenzene. First, it can be achieved through a palladium-catalyzed cross-coupling reaction. Iodobenzene and 4-phenylboronic acid are taken as raw materials, in the presence of palladium catalysts such as tetra (triphenylphosphine) palladium [Pd (PPh 🥰) ], with potassium carbonate as a base, in a mixed solvent of organic solvents such as dioxane and water, heating and stirring the reaction. In this process, the palladium catalyst activates iodobenzene and boric acid to promote the coupling of the two to form the target product 4- (4-phenylphenyl) iodobenzene.
Second, the Ullmann reaction can be used. Iodobenzene and 4-iodobiphenyl are used as starting materials, copper powder or cuprous iodide catalyst is added, potassium carbonate is used as base, and high-boiling organic solvent such as N, N-dimethylformamide (DMF) is refluxed at high temperature. In this reaction, the copper catalyst promotes the coupling of two molecules of halogenated aromatics to obtain 4- (4-phenylphenyl) iodobenzene.
Furthermore, the reaction can be reacted with the help of Grignard reagents. 4- (4-phenylphenyl) iodobenzene can also be formed by reacting 4-bromobiphenyl with iodobenzene in an organic solvent such as anhydrous ether or tetrahydrofuran under the action of a suitable catalyst such as nickel catalyst. In this reaction, the Grignard reagent has high activity and can undergo nucleophilic substitution reaction with iodobenzene to form carbon-carbon bonds.
The above synthesis methods have their own advantages and disadvantages. In actual operation, the appropriate synthesis path should be reasonably selected according to the availability of raw materials, the difficulty of controlling the reaction conditions, and the purity requirements of the target product.

4- (4-phenylphenyl) iodobenzene is a commonly used reagent in organic synthesis. Many things must be paid attention to when storing and transporting it.
Let's talk about storage first. This compound is quite sensitive to light and air. Under light, the chemical bond is easily broken, causing it to decompose, so it must be stored in a light-shielding container. As for air, oxygen can cause oxidation and deteriorate 4- (4-phenylphenyl) iodobenzene, so make sure that the storage container is well sealed, and it is best to fill it with inert gases such as nitrogen to isolate the air. In addition, temperature is also critical, and high temperature will accelerate its decomposition rate. It should usually be placed in a low-temperature environment, such as a refrigerator freezer, and the temperature should be maintained at 2-8 ° C.
Besides transportation, because of its certain chemical activity, the packaging must be stable. Appropriate packaging materials should be used to ensure that the packaging is not damaged due to vibration and collision during transportation. And the transportation environment should also be paid attention to. It is necessary to avoid high temperature and strong light. It is advisable to choose a cool and shaded transportation vehicle. At the same time, the transportation personnel should also be familiar with its chemical properties and emergency treatment methods to prevent accidents from happening. In short, the storage and transportation of 4- (4-phenylphenyl) iodobenzene, shading, sealing, temperature control, and stable packaging and personnel awareness characteristics are all essential points.

4 - (4 - phenylphenyl) iodobenzene, the price of this substance in the market is difficult to determine. The price of the cover is often changed due to many reasons. First, the amount of production, if the product is abundant, the price is flat; if the product is thin, the price is easy to be high. Second, if you ask for a small number, the user is numerous, and if you want prosperity, the price will increase; if you want a small number, if you want a small amount, the price will drop. Third, it is difficult and easy to make. If the system is difficult, labor-intensive, and expensive, the price will be high; if the system is easy, the labor and materials will be cheap, the price will be appropriate. Fourth, the sellers are different, and the prices of various merchants are also different, or depending on the height of the original, or the amount of profit. Therefore, if you want to know the exact price, you need to consult all pharmaceutical companies, chemical material dealers, or check carefully on the platform of the market, so that you can get a more realistic price. However, the current price may change in an instant, so if you seek the real price, you need to ask often.
