First of all, its appearance, at room temperature, this compound is often in a solid state, its color or light yellow, or powder, crystal genus, the appearance of fine, with a certain luster.
As for the melting point, it is about a specific temperature range, which is determined by the interaction between atoms in its molecular structure. The functional groups of bromine, fluorine, nitro and other molecules interact with each other, causing the lattice energy to show a specific value, and the melting point also depends.

In addition, the volatility of this compound is low. Due to its strong intermolecular force, it is difficult for molecules to escape from the liquid surface and enter the gas phase, so it is not significant under normal temperature and pressure.
In summary, the physical properties of 1-bromo-2,4-difluoro-6-nitrobenzene, such as appearance, melting point, boiling point, solubility, density, volatility, etc., play a key guiding role in its preparation, application, and storage.

The synthesis of 1-bromo-2,4-difluoro-6-nitrobenzene is an important topic in the field of organic synthesis. The synthesis path can be achieved by multiple methods, and one of the commonly used methods is described below.
The starting material is selected as 2,4-difluoroaniline, and the nitration reaction is first performed. This step is quite critical. Dissolve 2,4-difluoroaniline in an appropriate amount of sulfuric acid and nitric acid mixture, and slowly add the mixed acid dropwise under a specific low temperature environment to maintain the temperature stability of the reaction system to prevent the growth of side reactions. The ratio of nitric acid and sulfuric acid mixture needs to be precisely prepared, and this ratio has a great impact on the selectivity and yield of the reaction. After the reaction is completed, 2,4-difluoro-6-nitroaniline can be obtained through neutralization, extraction and other operations.
Then, 2,4-difluoro-6-nitroaniline is subjected to diazotization. Take it and dissolve it in an appropriate amount of hydrochloric acid, cool it to a low temperature, add sodium nitrite solution dropwise to form a diazonium salt. This diazonium salt is extremely unstable and needs to be reacted immediately.
The last step is the bromination reaction. The solution of diazonium salt is added dropwise to the hydrobromic acid solution containing cuprous bromide, and the reaction is heated. Cuprous bromide acts as a catalyst here to promote the substitution of diazo groups with bromine atoms to obtain 1-bromo-2,4-difluoro-6-nitrobenzene. After the reaction, the target product with high purity can be obtained by separation and purification methods such as distillation and column chromatography.
During the synthesis process, the reaction conditions of each step, such as temperature, ratio of reactants, reaction time, etc., need to be carefully controlled to ensure high yield and purity. This is the key to the synthesis of 1-bromo-2,4-difluoro-6-nitrobenzene.

1-Bromo-2,4-difluoro-6-nitrobenzene is an important intermediate in organic synthesis. When storing and transporting, the following numbers should be paid attention to:
First, the storage environment should be kept cool and dry. This compound is extremely sensitive to humidity, and moisture can easily lead to quality deterioration. Just like ancient books, if stored in a humid place, it is easy to be moth-eaten and moldy. Therefore, it needs to be stored in a dry and well-ventilated place, away from water sources and moisture to prevent adverse reactions such as hydrolysis.
Second, avoid light. 1-Bromo-2,4-difluoro-6-nitrobenzene is photosensitive, and under light conditions, it may induce photochemical reactions, causing its structure to change, affecting its chemical properties and uses. Just like the paintings and calligraphy treasured by the ancients, they are afraid of direct light and need to be properly stored in a darkroom. Therefore, when storing, it is advisable to use brown bottles or light-shielding packaging materials to block light exposure.
Third, the storage temperature also needs to be strictly controlled. Excessive temperature may cause it to decompose, and too low temperature may cause it to solidify, which will cause inconvenience to access and use. Generally speaking, it should be stored in a suitable low temperature environment, but not below its freezing point. This is like storing fine wine. If the temperature is too high, the wine will deteriorate easily, and if it is too low, the wine will freeze, which will damage the quality of the wine.
Fourth, during transportation, make sure that the packaging is tight and firm. This compound is toxic and corrosive to a certain extent. If the packaging is damaged, leakage will not only endanger the health of the transporters, but also may pollute the environment. Just like transporting fragile and toxic treasures, it needs to be properly packaged in a sturdy container to prevent damage and leakage.
Fifth, it should be stored and transported separately from oxidants, reducing agents, alkalis and other substances. 1-Bromo-2,4-difluoro-6-nitrobenzene can chemically react with these substances, resulting in dangerous conditions. This is like weapons of different attributes, which cannot be mixed in one place, otherwise they will collide and react with each other, and there will be a danger of disaster.
In short, the storage and transportation of 1-bromo-2,4-difluoro-6-nitrobenzene should be carefully followed, and relevant regulations and operating procedures should be followed to ensure the safety of personnel and the quality of materials.

1-Bromo-2,4-difluoro-6-nitrobenzene, the market price range of this product is difficult to determine. Its price often varies due to many factors, such as raw material cost, preparation process, market supply and demand.
At the end of the raw material cost, the price of bromine, fluoride, nitro compounds and other raw materials required for its preparation fluctuates from time to time. If raw materials are scarce, or their production costs rise, the price of 1-bromo-2,4-difluoro-6-nitrobenzene will also increase.
Preparation process is also key. Complex and high-tech processes are often accompanied by high equipment input and operation costs, so the price of the product will rise; if the process is simple and efficient, the cost may be reduced, and the price can be more affordable.
Market supply and demand are particularly affected. If the market has strong demand for 1-bromo-2,4-difluoro-6-nitrobenzene, and the supply is limited, its price will rise; on the contrary, if the supply is abundant and the demand is insufficient, the price will inevitably decline.
According to the past market, the price may fluctuate between tens of yuan and hundreds of yuan per gram. However, this is only a rough range. The current exact price needs to be consulted with the chemical product supplier in detail, and the latest quotation shall prevail. The chemical market is volatile, and prices are often not static.
