1 - chloro - 2 - (4 - ethoxybenzyl) - 4 - iodobenzene is an organic compound with unique physical properties. It is mostly solid under normal conditions, and the molecules are arranged in an orderly manner due to strong intermolecular forces. In terms of melting point, chlorine, iodine atoms and ethoxybenzyl groups in the molecular structure affect the intermolecular interaction, and the melting point is higher.
Looking at its solubility, the compound is non-polar or weakly polar. According to the principle of similar miscibility, it has good solubility in non-polar or weakly polar organic solvents, such as benzene, toluene, and dichloromethane. Due to the dispersion force between the solute and the solvent molecules, it can promote dissolution. In water with strong polarity, it is difficult to dissolve due to the inability to form effective interactions between molecules.
The compound has a certain density. Because the molecule contains heavy atoms of chlorine and iodine, the mass per unit volume increases, and the density is greater than that of common organic solvents.
Its volatility is low, and the structure of chlorine, iodine atoms and benzene rings increases the intermolecular force. High energy is required to overcome this force to vaporize it, so it evaporates slowly at room temperature.
The physical properties of 1-chloro-2- (4-ethoxybenzyl) -4-iodobenzene are determined by its molecular structure, which is of great significance for its application in organic synthesis, materials science and other fields. Different physical properties make the compound suitable for different scenarios, such as specific reaction solvents or material preparation raw materials.

The chemical synthesis of 1-chloro-2- (4-ethoxybenzyl) -4-iodobenzene requires delicate design and careful operation. The process of this synthesis can follow the following steps:
First, take 4-ethoxybenzyl alcohol as the starting material, and react with appropriate halogenating reagents, such as thionyl chloride or phosphorus trichloride, to obtain 4-ethoxybenzyl chloride. In this reaction, the halogenated reagent and 4-ethoxybenzyl alcohol need to be mixed at a suitable temperature and reaction time, usually in an inert gas protective atmosphere, in an organic solvent such as dichloromethane, heated and stirred moderately, so that the reaction can be fully carried out, and then 4-ethoxybenzyl chloride is efficiently generated.
Second, take another 1-chloro-4-iodobenzene and react it with metallic magnesium to form a Grignard reagent. This process requires the addition of magnesium chips and 1-chloro-4-iodobenzene mixture slowly under the harsh conditions of anhydrous and oxygen-free, using anhydrous ether or tetrahydrofuran as a solvent, initiating the reaction to obtain the corresponding Grignard reagent.
Subsequently, the 4-ethoxybenzyl chloride obtained above is slowly added to the reaction system containing 1-chloro-4-iodobenzyl-Grignard reagent. This addition reaction also needs to be carried out at a low temperature and in an anhydrous and oxygen-free environment. With the help of the high activity of Grignard reagents, the nucleophilic attack on 4-ethoxybenzyl chloride is realized, thereby generating 1-chloro-2- (4-ethoxybenzyl) -4-iodobenzene.
The reaction is over, and the product needs to be separated and purified. By column chromatography, silica gel can be used as the stationary phase, and a suitable eluent, such as the mixed solvent of petroleum ether and ethyl acetate, can be selected to achieve the purpose of separation and purification according to the difference in the partition coefficients of the product and impurities between the stationary phase and the mobile phase, and finally obtain high-purity 1-chloro-2 - (4-ethoxybenzyl) - 4-iodobenzene. Throughout the synthesis process, each step needs to carefully control the reaction conditions to ensure the yield and purity of the product.

Today there is 1 - chloro - 2 - (4 - ethoxybenzyl) - 4 - iodobenzene, and its market price is difficult to determine. It is difficult to cover the changes in market prices due to various factors.
The first to bear the brunt is the difficulty of production. If the synthesis of this product is complicated, the raw materials are scarce, and the processes are complicated, the production cost will be high, and the price will be high. If the preparation method is simple, the raw materials are abundant and easy to obtain, the cost can be reduced, and the price will become easier.
Furthermore, the situation of supply and demand is related to the price. If the market demand for this product is strong, but the supply is limited, the so-called "rare is expensive", the price will rise. On the other hand, if there is a lack of demand and an excess supply, the merchant will destock or reduce the price to promote.
Again, the trend of industry competition will also affect. If there are many producers of this compound in the market, the merchants will compete for shares, or compete on prices, or cause prices to decline. However, if the market is almost monopolized and only a few companies control the supply, the pricing power will be in their hands, and the price may be high.
There are also market fluctuations. The good or bad economic situation and changes in policies and regulations can cause prices to fluctuate. If the economy is prosperous and various industries are prosperous, the demand for this compound may increase, and the price will follow; if the policy restricts production and trade, or affects its cost and circulation, the price will change.
Therefore, to know the exact market price of 1 - chloro - 2 - (4 - ethoxybenzyl) - 4 - iodobenzene, it is necessary to carefully consider the production, supply and demand, competition and market fluctuations, and pay attention to market dynamics in real time to obtain a more accurate price.

1 - chloro - 2 - (4 - ethoxybenzyl) - 4 - iodobenzene, this is an organic compound. In the ancient classical style of "Tiangong Kaiwu", when discussing its safety, it can be made as follows:
This compound contains elements such as chlorine and iodine, and its properties may be harmful. The existence of chlorine and iodine atoms makes this substance chemically active. Its activity may cause it to react easily with other substances. In case of open flame or hot topic, there may be a risk of combustion or explosion.
And halogenated aromatic hydrocarbons are mostly toxic. If the human body comes into contact with it, or penetrates through the skin, breathes and inhales, and eats by mistake, it invades the body and damages the viscera. Inhalation or irritation of the respiratory tract, causing cough, asthma and other diseases; skin contact or cause redness, swelling, itching, burning; ingestion or stomach injury, vomiting, abdominal pain disease.
When storing, choose a cool and ventilated storage, away from fire and heat sources. It should be stored separately with oxidants and edible chemicals, and should not be mixed to prevent accidental reactions. When handling, be sure to pack and unload lightly to prevent leakage due to package damage.
In the operating room, ensure good ventilation. Operators need to wear protective clothing, protective gloves and masks to prevent contact injuries. In the event of a leak, personnel should be evacuated to a safe area as soon as possible to cut off the fire source. Emergency responders should wear positive pressure self-contained breathing apparatus, anti-virus clothing, and absorb it with inert materials such as sand and vermiculite. After collection, they should be properly disposed of.
