What are the synthesis methods of 3-Chloro-4- (3-fluorobenzyloxy) -aniline?

The synthesis method of 3-chloro-4- (3-fluorobenzyloxy) aniline is now your way.

One method is to take 3-chloro-4-hydroxyaniline as the starting material. In this compound, react with 3-fluorobenzyl halide, such as 3-fluorobenzyl chloride or 3-fluorobenzyl bromide, in an alkaline medium. Usually with the help of potassium carbonate, sodium carbonate and other bases, in suitable organic solvents, such as N, N-dimethylformamide (DMF), acetonitrile, etc., heat and stir it. This reaction is a nucleophilic substitution reaction. The oxygen atom of the hydroxyl group is nucleophilic and can attack the carbon connected to the halogen atom in the 3-fluorobenzyl halide. The halogen ion leaves, and then forms 3-chloro-4- (3-fluorobenzoxy) aniline.

There is another way. 3-chloroaniline can be protected first to prevent the amino group from interfering in subsequent reactions. Protect the amino group with an appropriate protective group, such as tert-butoxycarbonyl (Boc), to obtain the protected 3-chloroaniline derivative. Afterwards, the derivative is reacted with 3-fluorobenzyl halide in basic conditions and organic solvents similar to the above, and 3-fluorobenzyl oxide is introduced. After the benzyl oxide is introduced, the protective group is removed and the amino group is restored through an appropriate reaction. Finally, 3-chloro-4- (3-fluorobenzyl) aniline is obtained.

There is another way. It can start from 4- (3-fluorobenzyl) -1-nitrobenzene. First, 3-fluorobenzyl halide is reacted with p-nitrophenol under alkaline conditions to obtain 4- (3-fluorobenzyl) -1-nitrobenzene. Then the nitro compound is reduced to an amino group by a suitable reducing agent, such as iron-hydrochloric acid, tin-hydrochloric acid, or by catalytic hydrogenation, and the target product 3-chloro-4- (3-fluorobenzyl) aniline can also be obtained. All methods have their own advantages and disadvantages. When experimenting, it should be selected carefully according to the actual situation, such as the availability of raw materials, the difficulty of reaction conditions, and the high or low yield.

What are the physical properties of 3-Chloro-4- (3-fluorobenzyloxy) -aniline?

3-Chloro-4- (3-fluorobenzoxy) aniline is a kind of organic compound. According to its physical properties, it is mostly in a solid state under normal conditions, and its structure is relatively stable due to intermolecular forces. Its melting point is the critical temperature at which the substance changes from solid to liquid state. The exact value can be obtained by experimental determination. This value is of great significance for the identification and purification of the compound.

Furthermore, its solubility is also a key property. In organic solvents, such as common ethanol and ether, the compound may have a certain solubility by virtue of the principle of similar miscibility. Due to the similarity between the molecular structure of organic solvents and 3-chloro-4- (3-fluorobenzoxy) aniline, they can form a weak interaction force with each other and then dissolve. However, in water, because the molecular polarity does not exactly match the water molecule, the solubility is relatively low.

The color of this compound may be white to off-white, and this color characteristic is also helpful for preliminary identification. Although its odor, or a special organic odor, is difficult to describe accurately, experienced chemical practitioners can use it to assist in identification.

In addition, its density is related to the mass per unit volume, and accurate measurement can be done with the help of specific instruments. This value is an indispensable parameter for the material ratio and reaction system design in chemical production.

The physical properties of 3-chloro-4- (3-fluorobenzoxy) aniline are diverse and have important value in many fields of chemical research and chemical production. Only by carefully exploring and mastering these properties can we better control its application.

What are the chemical properties of 3-Chloro-4- (3-fluorobenzyloxy) -aniline

3-Chloro-4- (3-fluorobenzoxy) aniline, the chemical properties of this substance are very important, and it is related to many chemical and chemical things.

Its physical properties, at room temperature or in a solid state, have specific melting points and boiling points. These parameters are key guidelines in separation, purification and practical applications. The level of melting point can help to determine its purity. If the purity is high, the melting point range is often narrow.

From the perspective of chemical activity, amino groups (-NH2O) give it alkaline properties, which can react with acids to form corresponding salts. This property can be used in organic synthesis to form new chemical bonds and prepare various derivatives. Chlorine atoms (-Cl) are also active groups and can participate in nucleophilic substitution reactions. Due to their electronegativity, the electron cloud density of the benzene ring can be changed, which affects the activity and check point selectivity of other reactions on the benzene ring. Under suitable conditions, chlorine atoms can be replaced by many nucleophiles to expand the structural diversity of molecules.

3 -fluorobenzoxy moiety, the presence of fluorine atoms increases the stability and fat solubility of molecules. Benzoxy groups can be broken under specific conditions, providing the possibility for further modification of molecules. For example, in some reaction systems, benzoxy groups can be used as protective groups. After the reaction is completed, they can be selectively removed to accurately construct the target product.

Due to these chemical properties, this compound has potential application value in the fields of medicine, pesticides and materials science. In pharmaceutical research and development, it may be used as a lead compound to develop new drugs through structural modification and optimization; in the field of pesticides, its unique structure may endow good biological activity to prepare high-efficiency and low-toxicity pesticide products.

What is the price range of 3-Chloro-4- (3-fluorobenzyloxy) -aniline in the market?

I don't know what the price range of 3 - Chloro - 4 - (3 - fluorobenzyloxy) - aniline is on the market. This is a fine chemical, and its price is determined by many factors.

First, the difficulty of preparation has a great impact. If its synthesis requires complicated steps, special raw materials or harsh reaction conditions, the cost will be high, and the price will also rise. For example, the need for rare catalysts or multiple purification steps will increase the cost.

Second, the state of market supply and demand is the key. If many industries, such as pharmaceuticals, pesticides, etc., have high demand for them, but the supply is limited, the price will rise; on the contrary, if there is little demand, the supply will exceed the demand, and the price will decline.

Third, the price of raw materials also plays a role. If the price of raw materials for synthesizing this compound fluctuates, the price will also change accordingly. For example, the price of raw materials fluctuates due to factors such as origin and season, and the price of products is difficult to stabilize.

Fourth, the scale of production is also related to the price. In large-scale production, due to the scale effect, the unit cost may be reduced and the price may be more affordable; in small-scale production, the cost is higher and the price will be higher.

Because I do not know the specific market information at the moment, it is difficult to determine its price range. For exact prices, consult chemical product suppliers, trading platforms, or refer to recent market surveys so that accurate price ranges can be obtained.
