What is the synthesis method of 1- (4-fluorobenzyl) piperazine?

1 - (4 - fluorobenzyl) piperazine is an organic compound. Although the method of its synthesis is not detailed in ancient books, it can be deduced according to today's chemical reasons.

Usually, piperazine can be prepared by reacting with 4 - fluorobenzyl halide. First take an appropriate amount of piperazine, put it in a suitable reaction vessel, and dissolve it in an organic solvent, such as ethanol, acetonitrile, etc. These two can make the piperazine evenly dispersed and facilitate the reaction. Then 4 - fluorobenzyl halide is slowly dropped into it, and the halide can be selected from 4 - fluorobenzyl chloride or 4 - fluorobenzyl bromide. This method of dropwise addition can control the reaction rate and avoid overreaction.

When reacting, it needs to be adjusted to a suitable temperature, usually in the state of heating reflux, between about 60-80 degrees Celsius. Such a temperature can promote the reaction to accelerate without causing the decomposition of substances. And it should be stirred to make the reactants fully in contact to make the reaction more complete.

After the reaction is completed, the product can be separated by an appropriate method. It can be distilled under reduced pressure to remove the solvent, and then by column chromatography, according to the different distribution of the product and impurities in the fixed phase and the mobile phase, to obtain pure 1- (4-fluorobenzyl) piperazine. In column chromatography, choose the appropriate eluent, such as the mixture of petroleum ether and ethyl acetate, and adjust the ratio to achieve the best separation effect.

Or there are other methods. 4-Fluorobenzaldehyde can be reacted with piperazine first to obtain the intermediate, and then the reduction step can also obtain the target product. First, 4-Fluorobenzaldehyde and piperazine are mixed in a solvent, catalyzed by a weak acid, such as acetic acid, at room temperature or slightly higher temperature to form an imine intermediate. Later, a reducing agent, such as sodium borohydride, reduces the imine to 1 - (4-fluorobenzyl) piperazine. When reducing, pay attention to control the reaction conditions to avoid side reactions caused by excessive reduction.

In short, the synthesis of 1- (4-fluorobenzyl) piperazine method, depending on the raw materials and reaction conditions used, but all require fine operation, control of each step of the reaction, to obtain satisfactory yield and purity.

What is the price range of 1- (4-fluorobenzyl) piperazine in the market?

What is the price of 1 - (4 -fluorobenzyl) piperazine in the market? In the chemical industry, the price range of this drug often varies depending on the quality, quantity, and seller.

If the purchase amount is quite small, if only a few grams are needed, the price per gram may be in the tens of yuan at the sales place of chemical reagents. Cover the reagent grade product, the preparation is fine, and the purity is quite high, so the price is high.

If the purchase amount is slightly increased, reaching hundreds of grams or even several kilograms, the price per kilogram may be in the hundreds of yuan in terms of industrial grade. Because of its scale of production, the cost is slightly reduced, and the quality may be slightly inferior to the reagent grade.

There are many factors that affect its price. First, the price of raw materials. If the price of 4-fluorobenzyl and piperazine raw materials increases, the price of this drug will also rise.
