This alcohol can be used as an intermediate to further participate in esterification, substitution and other reactions.

Because its molecule contains fluorobenzyloxy, the benzyl group can be substituted with benzyl hydrogen. Under appropriate reagents and conditions, benzyl hydrogen can be replaced by halogen atoms, introducing new functional groups, expanding its chemical transformation path, and has potential applications in drug synthesis, material chemistry and other fields.

What is the common synthesis method of 4- (3-fluorobenzyloxy) benzaldehyde

4- (3-fluorobenzoxy) benzaldehyde is also an organic compound. Its common synthesis method is mostly based on various reactions in organic chemistry.

Usually, 4-hydroxybenzaldehyde and 3-fluorobenzyl halide are used as raw materials for nucleophilic substitution. Take 4-hydroxybenzaldehyde first, put it in an appropriate amount of organic solvent, such as N, N-dimethylformamide (DMF), and add a base such as potassium carbonate or sodium carbonate to increase the nucleophilicity of 4-hydroxybenzaldehyde. The base can deprotonate the hydroxyl group of 4-hydroxybenzaldehyde, and increase the activity of phenoxy anions. Next, a 3-fluorobenzyl halide, such as 3-fluorobenzyl chloride or 3-fluorobenzyl bromide, is slowly added. The halogen atom of this halide is attacked by phenoxy negative ions, and the halogen atom leaves, and then forms a carbon-oxygen bond, resulting in 4- (3-fluorobenzoxy) benzaldehyde. During the reaction, the temperature should be controlled in a moderate range, usually between room temperature and 60 ° C. If the temperature is too low, the reaction is slow; if it is too high, the side reaction will occur.

Or it can be obtained by reduction of 4- (3-fluorobenzoxy) benzoic acid. With an appropriate reducing agent, such as sodium borohydride or lithium aluminum hydride, in a suitable solvent, such as anhydrous tetrahydrofuran, the reduction reaction of 4- (3-fluorobenzoxy) benzoic acid is carried out. The reduction power of sodium borohydride is slightly slower, but the operation is easy; lithium aluminum hydride has strong activity and needs to be strictly anhydrous and anoxic. After reduction, the carboxylation is changed to an aldehyde group, and 4- (3-fluorobenzoxy) benzaldehyde is also obtained.

The way of synthesis, each method has its advantages and disadvantages. For nucleophilic substitutes, the raw materials are easy to obtain and the operation is relatively simple; the reduction method, although it needs to be handled carefully, can be derived from the corresponding carboxylic acid, which is also valuable. It all depends on the principle of

What is the market price of 4- (3-fluorobenzyloxy) benzaldehyde?

4- (3-fluorobenzoxy) benzaldehyde, an important organic synthesis intermediate in the field of fine chemicals, is often found in the preparation process of pharmaceuticals, pesticides and materials. However, its market price is difficult to specify, because many factors will affect it.

The first to bear the brunt is the cost of raw materials. 3-fluorobenzyl alcohol and p-hydroxybenzaldehyde are the main raw materials for synthesizing this compound, and their price fluctuations will directly affect the cost of 4- (3-fluorobenzoxy) benzaldehyde. If the supply of raw materials is tight, or interfered by factors such as market supply and demand, and the complexity of production processes, prices will rise, which will then drive up the price of finished products.

Secondly, the production process is also crucial. Advanced and efficient production processes can improve product purity and yield, and reduce production costs; on the contrary, if the process is backward, not only the yield is low, but the product quality may also be poor, the cost will inevitably increase, and the price will rise.

Furthermore, the market supply and demand relationship is the key. If downstream industries such as pharmaceuticals and pesticides have strong demand for 4- (3-fluorobenzoxy) benzaldehyde, but the supply is relatively insufficient, the price will rise; conversely, if the market demand is weak and the supply is excessive, the price will fall.

In addition, factors such as macroeconomic conditions, policies and regulations, transportation costs, etc., will also play a role in its price to a certain extent.

In summary, the market price of 4 - (3 - fluorobenzoxy) benzaldehyde fluctuates. For accurate prices, consult the relevant manufacturers, distributors, or inquire in detail through the chemical product trading platform to obtain more accurate price information.

What are the storage conditions for 4- (3-fluorobenzyloxy) benzaldehyde?

4- (3-fluorobenzoxy) benzaldehyde is one of the organic compounds. Its storage conditions are crucial, which is related to the quality and stability of this compound.

To properly store this compound, the temperature of the first environment should be the temperature. It should be stored in a cool place, because high temperature can easily cause chemical reactions to occur and damage its structure and properties. Generally speaking, the temperature is between 2 and 8 degrees Celsius. This temperature range can slow down the movement rate of molecules, reduce the possibility of chemical reactions, and thus maintain their chemical stability.

The second is the humidity of the environment. Be sure to keep the storage place dry to avoid moisture. Moisture can cause many problems, such as hydrolysis reactions, which can change the chemical composition of the compound. A desiccant can be placed near the storage container to absorb water vapor in the air and keep it dry.

Furthermore, the choice of storage container should not be ignored. Containers with good sealing performance should be used to prevent the intrusion of air, moisture and other impurities. Glass containers or specific plastic containers are optional if they are well sealed. And the container should be protected from light. The compound may be sensitive to light, under light, or cause luminescent chemical reactions to cause it to deteriorate.

In addition, the storage place should be kept away from fire, heat and strong oxidants. This compound has certain chemical activity, and may be at risk of combustion or explosion in case of fire, heat or strong oxidants. Therefore, the storage must be well ventilated to disperse the volatile gases that may accumulate and reduce safety hazards.

In summary, the storage of 4- (3-fluorobenzoxy) benzaldehyde should be controlled in a cool place of 2-8 degrees Celsius, keep it dry, choose a sealed container protected from light, and keep it away from fire, heat and strong oxidants, so as to ensure the quality and stability of this material.
