The common methods for synthesizing 2-bromo-3,4-difluoro-1-nitrobenzene are as follows.
First, the compound containing the benzene ring is used as the starting material, and it is obtained through a series of reactions such as halogenation and nitrification. The benzene ring is brominated first, which can precisely introduce bromine atoms into specific positions. Commonly used brominating reagents include bromine ($Br_2 $). Under the action of suitable catalysts, such as iron powder ($Fe $) or iron tribromide ($FeBr_3 $), an electrophilic substitution reaction occurs to generate bromobenzene derivatives. Then, the fluorination reaction is carried out, and a suitable fluorination reagent can be selected, such as potassium fluoride ($KF $). Under specific reaction conditions, such as high temperature and the presence of a phase transfer catalyst, the fluorine atom replaces other atoms at the corresponding position on the benzene ring to form a benzene derivative containing bromine and fluorine. Finally, the nitration reaction is carried out, and the mixed acid composed of nitric acid ($HNO_3 $) and sulfuric acid ($H_2SO_4 $) is used as the nitrifying reagent to promote the introduction of nitro ($- NO_2 $) into the benzene ring to achieve the synthesis of 2-bromo-3,4-difluoro-1-nitrobenzene.
Second, benzene derivatives containing some of the target substituents can also be started. If the starting material already contains fluorine atoms, it can be brominated first. The method is such as the above bromination step to introduce bromine atoms precisely. After that, nitro groups are introduced through nitration reaction to obtain the target product. This way can reduce the reaction steps and improve the yield. In each step of the reaction, the reaction conditions, such as reaction temperature, reaction time, and reagent dosage, need to be strictly controlled to ensure the high efficiency and selectivity of the reaction. At the same time, the separation and purification of the product is also crucial. Column chromatography, recrystallization and other means are often used to obtain high-purity 2-bromo-3,4-difluoro-1-nitrobenzene.

2-Bromo-3,4-difluoro-1-nitrobenzene organic compounds, when storing and transporting, the following items should be paid attention to:
First, the storage place must be dry and well ventilated. Because of its hygroscopicity, humid environment is easy to deteriorate, good ventilation can prevent its accumulation and reduce safety risks. If placed in a dark, dry, well-ventilated warehouse, keep away from water sources and moisture.
Second, temperature control is also crucial. Avoid high temperature and severe cold, the appropriate temperature is usually between 2-8 ° C. High temperature or cause it to decompose, volatilize, severe cold or cause it to solidify, which affects quality. If refrigeration equipment is used to maintain a suitable temperature.
Third, this compound belongs to the category of dangerous goods, and must be separated from oxidizing agents, reducing agents, acids, alkalis, etc. when stored. Due to its active chemical properties, contact with the above substances or cause violent reactions, resulting in fires, explosions and other accidents. If it is stored in separate areas with other chemicals, it should be clearly marked.
Fourth, when transporting, it is necessary to ensure that the packaging is complete and sealed. Prevent leakage, because leakage not only pollutes the environment, but also poses a threat to the safety of transporters. Packaging materials should have good sealing and corrosion resistance, such as special sealed containers.
Fifth, the transportation process should be smooth, and it should absorb vibration and impact. Vibration and impact or damage the packaging, causing leakage, and or causing the compound to react with impact. Transport vehicles should be selected with good shock absorption performance, and they must be stable when driving.
Sixth, transportation and storage personnel should be professionally trained to be familiar with the characteristics of the compound, safe operation practices and emergency response methods. In this way, they can respond quickly in emergency situations and reduce hazards. Such as regular training and drills.

What you are asking is the market price of 2-bromo-3,4-difluoro-1-nitrobenzene. However, the price of this product often changes with time and is also affected by many factors, so it is difficult to make a sudden conclusion.
Looking at the state of the market in the past, the price of chemical materials often changed with supply and demand, the amount of raw materials, the difficulty of production, and the security of the current situation. If the demand for this product is strong, but the supply is limited, its price will rise; if the raw materials are abundant and the production is convenient, the price may decline.
The market of chemical industry is unpredictable. And the prices sold by different merchants are also similar, or the quality is different, or the region is different. It is also at this moment that business conditions change like the wind and clouds, and prices are also volatile.
To know the exact price, do not consult Jia people in the chemical market, or check the platform of professional market information. There can be real-time prices, which is accurate and reliable. However, with common sense, without knowing the details, it can only be said that the price fluctuates due to many factors, which is difficult to hide.
