Because the amino groups and halogen atoms in the structure of this compound can participate in complex chemical reactions to build a molecular framework for special functional materials. From this perspective, 2-amino-5-fluoro-3,4-dichlorobenzene plays an indispensable role in many important fields, providing a key material foundation for innovation and development in various fields.

2-Amino-5-fluoro-3,4-dichlorobenzene is one of the organic compounds. Its physical properties are quite important and are of significance in the fields of chemical industry and scientific research.
Looking at its appearance, it is often white to light yellow crystalline powder. This color state is easy to identify, and its purity and state can be preliminarily determined in many experiments and production processes.
When it comes to the melting point, it is about a specific temperature range. This characteristic is crucial for its separation, purification and identification operations. By accurately measuring the melting point, the purity of the compound can be determined. If the purity is high, the melting point range is narrow and approaches the theoretical value; if it contains impurities, the melting point is reduced and the range is wider.
Its boiling point is also a key physical property. The boiling point reflects the temperature at which the substance changes from liquid to gaseous under a specific pressure. This parameter is indispensable in separation methods such as distillation. According to the difference in boiling point, it can be effectively separated from the mixture.
Furthermore, the solubility of the compound is also worthy of attention. It has certain solubility in common organic solvents such as ethanol and ether, but relatively poor solubility in water. This solubility characteristic determines its application in different reaction systems and also affects its subsequent treatment and separation process.
In terms of density, although the value is relatively fixed, it also plays an important role in material balance and some processes involving volume and mass conversion. Accurate knowledge of density can ensure the accuracy of production and experiments.
In addition, the stability of 2-amino-5-fluoro-3,4-dichlorobenzene also belongs to the category of physical properties. Under normal conditions, its chemical properties are relatively stable, but in case of extreme conditions such as high temperature, strong acid, and strong base, chemical reactions and structural changes may occur. Therefore, it is necessary to pay attention to environmental conditions during storage and use to maintain the stability of its physical and chemical properties.

To prepare 2-amino-5-fluoro-3,4-dichlorobenzene, the method is as follows:
Take the appropriate starting material first, or choose the aromatic hydrocarbon derivative containing fluorine, chlorine, and amino groups. For example, 3,4-dichlorofluorobenzene is used as the starting material. Because it has fluorine atoms and chlorine atoms, an amino group can be introduced according to the principle of organic synthesis.
Nitro groups can be introduced into aromatic hydrocarbons by nitrification. With appropriate nitrifying reagents, such as mixed acids of concentrated nitric acid and concentrated sulfuric acid, under temperature control and time control, 3,4-dichlorofluorobenzene is nitrified to obtain 3,4-dichloro-5-fluoronitrobenzene. This step requires careful observation of the reaction conditions, because the selectivity of the aromatic hydrocarbon substitution reaction depends on the purity and yield of the product.
Next, the nitro group is reduced to an amino group. Suitable reducing agents can be selected, such as iron powder and hydrochloric acid system, or catalytic hydrogenation method. Taking iron powder and hydrochloric acid as an example, in a suitable solvent, such as ethanol, iron powder and hydrochloric acid, 3,4-dichloro-5-fluoro-nitrobenzene is reduced to obtain 2-amino-5-fluoro-3,4-dichlorobenzene. Catalytic hydrogenation requires a suitable catalyst, such as palladium carbon, to be reduced by hydrogen at a certain pressure and temperature.
Or from other sources. If an aromatic hydrocarbon containing an amino group is used as the starting point, fluorine and chlorine atoms are introduced first. However, the halogenation reaction also requires precise control of the conditions, and the appropriate halogenation reagent and catalyst are selected. For example, starting with aminobenzene, after protecting the amino group, a halogenation reaction is carried out to introduce chlorine and fluorine atoms, and then deprotect the target product. Protective amino groups can be used with groups such as acetyl groups, and deprotected with appropriate reagents after halogenation. This process step is slightly more complicated, but it can be selected according to the convenience of raw materials and conditions.
In short, the method of organic synthesis is not the same. According to factors such as raw materials, equipment, and cost, the optimal method should be selected to make the synthesis efficient and pure, and 2-amino-5-fluoro-3,4-dichlorobenz

I do not know for sure that 2 - Amino - 5 - Fluoro - 3,4 - Dichlorobenzene is in the market price range. The price of this chemical often varies due to many factors. The ease of production is a key factor. If the synthesis process is complicated, requires multiple steps and harsh conditions, involves rare or expensive raw materials and reagents, and requires high equipment and technology, the cost will be high, and the price will also rise.
Furthermore, the market supply and demand situation has a great impact. If there is a period of strong demand for it, such as pharmaceuticals, materials science and other fields, and the supply is limited, the price will rise; conversely, if the demand is low and the supply is sufficient, the price may fall.
In addition, product purity also affects the price. High-purity products require finer purification processes, consume more resources and costs, and the price is naturally higher than that of low-purity products. Different suppliers offer different prices due to differences in their own cost structure, production scale and market strategies. Large-scale manufacturers have low costs and competitive prices due to scale effects; small suppliers have higher costs and relatively high prices.
To know the exact price range, you can consult chemical reagent suppliers, such as Sinopharm Group Chemical Reagent Co., Ltd., search banner reagent company, etc., or inquire on chemical product trading platforms, such as Gade Chemical Network, etc. You can also communicate directly with relevant manufacturers for consultation, so as to obtain more accurate price range information.
