1-Bromo-2,3-difluoro-4-nitrobenzene is one of the organic compounds. Its physical properties have the following characteristics:
- ** Appearance and properties **: Under normal conditions, it is mostly light yellow to brown crystalline powder. The characterization of this color state can be used as a basis for identifying the compound. Looking at its color and observing its shape is quite beneficial in the preliminary determination of the substance.
- ** Melting point and boiling point **: The melting point is about 63-67 ° C, and the boiling point is about 263-264 ° C. The melting point is the critical temperature for the substance to change from solid to liquid; the boiling point is the key node for the liquefaction to gaseous state. These two temperature data are important reference indicators in the process of separation, purification and identification of substances. Knowing its melting point can assist in determining the purity of the compound through melting point measurement experiments. The melting point range of pure substances is relatively narrow. If impurities are contained, the melting point decreases and the melting range becomes wider. Knowing the boiling point can accurately control the temperature during separation operations such as distillation to achieve effective separation from other substances.
- ** Solubility **: Slightly soluble in water, but soluble in organic solvents such as ethanol, ether, acetone, etc. This solubility characteristic is closely related to the molecular structure. Water is a polar solvent, and the polarity of the compound is relatively weak, so the solubility in water is limited; while the polarity of the organic solvent is more matched with the compound, following the principle of "similar miscibility", so it is soluble. This property is of great significance in the post-processing process of organic synthesis reaction. It can take advantage of its solubility difference to select a suitable solvent for extraction, recrystallization and other operations to obtain pure products.
- ** Density **: about 1.915g/cm ³. Density, as an inherent property of substances, has applications in many fields. In chemical production, density data is indispensable when it comes to material measurement, equipment design, etc. By measuring the density, it can also assist in judging the purity of substances or identifying substances.
- ** Odor **: Usually has a special organic odor. Although the description of the odor is more subjective, in the actual operation process, the keen perception of the odor may warn the operator of the presence of the compound, providing some clues in the consideration of safety measures such as ventilation.
The physical properties of 1-bromo-2,3-difluoro-4-nitrobenzene are of important guiding significance in the fields of organic synthesis, analysis and testing, providing key basic data for scientific research and production practice.

The synthesis method of 1-bromo-2,3-difluoro-4-nitrobenzene used to rely on various organic synthesis methods. One of the common ones is based on benzene and obtained through multiple steps of delicate transformation.
At the beginning, the benzene ring is first brominated, and suitable brominating reagents are selected, such as liquid bromine and catalyst co-production, which can introduce bromine atoms at specific positions in the benzene ring. This step requires fine temperature control and ingredients to make bromine atoms fall precisely at the target check point.
Then, the method of difluorination of brominated benzene derivatives is applied. Commonly used fluorinating reagents, such as anhydrous potassium fluoride, under specific solvents and reaction conditions, fluorine atoms are replaced one by one in the hydrogen on the benzene ring, and attention should be paid to the position and order of fluorine atoms introduced to conform to the structure of the target product.
Finally, the work of nitrification is carried out. Select strong nitrifying reagents, such as mixed acids of concentrated nitric acid and concentrated sulfuric acid, and introduce nitro groups into the benzene ring at appropriate temperatures to accurately achieve the structure of 1-bromo-2,3-difluoro-4-nitrobenzene.
Or if other aromatic compounds are used as starting materials, according to their inherent structure, the purpose of synthesizing this compound can also be achieved through clever functional group transformation and substitution reactions. However, each method requires attention to the fine regulation of reaction conditions, such as temperature, pH, reaction time, etc., to ensure a smooth reaction, a pure product, and a considerable yield.

1-Bromo-2,3-difluoro-4-nitrobenzene is an important raw material in organic synthesis. During storage and transportation, there are many key considerations that need to be treated with caution.
When storing, the first environmental conditions. Because of its certain chemical activity, it should be placed in a cool, dry and well-ventilated place. If the ambient temperature is too high, it may cause chemical reactions and cause the material to deteriorate; and if the humidity is too high, it may cause the material to be damp, affecting its purity and stability. This is the first key to storage.
Furthermore, the packaging must be tight. Suitable packaging materials must be used to prevent its leakage. Due to its special nature, once it leaks or causes pollution to the surrounding environment, it may also endanger human health. Therefore, the sealing of the package is very important.
As for transportation, safety is the top priority. During transportation, it should be ensured that it does not react with other chemical substances. It is necessary to strictly follow the relevant transportation regulations and choose an appropriate transportation method. Substances that are contrary to the nature must not be mixed to avoid danger. At the same time, transportation equipment must also be kept in good condition to avoid packaging damage due to bumps, vibrations and other factors, which may lead to leakage accidents.
In addition, whether it is storage or transportation, it must be clearly marked. Indicate the name, nature, hazard and other important information of the substance so that relevant personnel can accurately know its characteristics during the handling process and take correct protective measures and emergency measures. In this way, the safety and stability of 1-bromo-2,3-difluoro-4-nitrobenzene during storage and transportation can be ensured.

The market price range of 1-bromo-2,3-difluoro-4-nitrobenzene is difficult to say exactly. The price of this compound is influenced by many factors, and it is difficult to predict.
First, the cost of raw materials has a great impact. The price fluctuations of bromine, fluoride and nitro-related raw materials required for the preparation of this compound are like ripple diffusion, which directly affects the price of 1-bromo-2,3-difluoro-4-nitrobenzene. If raw materials are scarce, the price must be high; if raw materials are abundant, the price may become stable and cheap.
Second, the difficulty of the production process is also the key. If the preparation process requires complicated steps, harsh conditions, or extremely high requirements for equipment, the cost of manpower and material resources will increase greatly, and the price will rise.
Third, the market supply and demand relationship is like an invisible giant hand, controlling the price trend. If the compound is in strong demand in the fields of medicine, pesticides, materials, etc., but the supply is limited, the price will rise; if the demand is weak and the supply is excessive, the price will be at risk of falling.
Fourth, regional factors should not be ignored. In different places, due to different transportation costs, tax policies, and the degree of market competition, the price will also vary.
According to past market conditions, the price may range from hundreds to thousands of yuan per kilogram. However, this is only a general range, and the actual price depends on the specific time, place, and transaction situation. If you want to know the exact price, you need to check the chemical product trading platform in detail, consult relevant suppliers or industry insiders, and then clarify.
