What are the synthesis methods of 1- [5- (3-chloro-2-fluorobenzyl) -2,4-dimethoxyphenyl] ethyl ketone?

To prepare 1 - [5 - (3 - cyanogen - 2 - hydroxyethyl) - 2,4 - diacetyl anisole, there are several methods for its synthesis.

First, the target structure can be constructed from the raw material through a multi-step reaction. First select an appropriate benzene-containing compound, such as an anisole derivative, and perform a substitution reaction. Using an acylation reagent, such as acetyl chloride and an appropriate catalyst, such as anhydrous aluminum trichloride, at a suitable temperature and reaction environment, the acetyl group is introduced at a specific position in the benzene ring to obtain an anisole derivative containing 2,4 - diacetyl group. After that, try to introduce the 3-cyanogen-2-hydroxyethyl structure. Nucleophilic substitution reaction can be carried out with the previous product under basic conditions by suitable halogenated hydrocarbons, such as halogenated ethane with cyanogen and hydroxyl protection. Finally, the target product can be obtained by appropriate deprotection steps.

Second, a reverse synthesis analysis strategy can also be used. The target molecule is disassembled, and the required raw materials and reaction steps can be inverted from its structural characteristics. For example, first consider how to construct the part of 3-cyanogen-2-hydroxyethyl group connected to the benzene ring. The intermediate containing cyanogen and hydroxyl group can be prepared first, and then connected with the 2,4-diacetyl-containing anisole fragment through suitable reactions, such as nucleophilic addition or condensation reaction. During the reaction process, it is necessary to pay attention to the activity and selectivity of each functional group, and rationally use the protective group strategy to avoid unnecessary side reactions, so as to improve the reaction yield and the purity of the target product. In this way, the purpose of synthesizing 1 - [5 - (3-cyanogen-2-hydroxyethyl) -2,4-diacetyl anisole can be achieved through a carefully designed reaction in multiple steps.

What are the physical and chemical properties of 1- [5- (3-chloro-2-fluorobenzyl) -2,4-dimethoxyphenyl] ethyl ketone?

1-% [5- (3-cyano-2-hydroxyethyl) -2,4-diacetylphenyl] acetic acid, this compound has a variety of physical and chemical properties. Its appearance may vary depending on the purity and crystalline state, and it may usually appear as a white to light yellow crystalline powder. This is due to the interaction of various groups in the molecular structure, which affects the reflection and absorption of light.

From the perspective of solubility, the compound may have certain solubility in organic solvents such as ethanol and acetone. This is because the organic groups in its molecular structure can form van der Waals forces or hydrogen bonds between organic solvent molecules, which prompts the molecules to disperse in the solvent. However, the solubility in water may be poor because the overall hydrophilicity of the molecule is relatively weak. The melting point of

is also one of the important physical properties. The specific value depends on the strength of the intermolecular force. The acetyl group, cyano group and other groups in the structure will affect the intermolecular force, so that the melting point is in a specific range.

In terms of chemical properties, the carboxyl group in the molecule is acidic and can neutralize with the base to form corresponding salt compounds. The cyanyl group is more active and can be hydrolyzed under certain conditions to convert into other functional groups such as carboxyl or amide groups. Under suitable reaction conditions, the acetyl group may participate in the substitution reaction or condensation reaction, showing the rich chemical reactivity of the compound. These properties make it potentially valuable in the field of organic synthesis.

What is the price range for 1- [5- (3-chloro-2-fluorobenzyl) -2,4-dimethoxyphenyl] ethyl ketone on the market?

Today, there is a chemical compound, named 1 - [5 - (3 - cyanogen - 2 - acetylamino) - 2,4 - diethoxyphenyl] acetic acid, to know its market price.

However, there is no immediate answer. The market price is often affected by general factors. First, the cost of production. The cost of raw materials, the ease of extraction, and the amount of energy consumption can all affect the cost. The cost is high or high. Second, the situation of supply and demand. If the demand is low and the supply is low, the price will rise; the supply is low and the demand will decline. Third, the difference in quality. Those with high quality are often low. Fourth, the market is low.


In addition, the use of this compound is also different. If it is widely used, such as in important fields such as oil and chemical processing, it may be affected by the phase.

If you want to get the cut grid, check the market of chemical raw materials, and provide suppliers of chemical raw materials, compare the quality of different sources, and combine the above factors, you can get the quality of the price.
