3-Bromo-5-fluorodifluoromethylbenzene is one of the organic compounds. Its chemical properties are unique and it has a wide range of uses in the field of organic synthesis.
In this compound, the presence of bromine atoms, fluorine atoms and difluoromethyl gives it specific chemical activity. Bromine atoms have good leaving properties and can be used as leaving groups in many nucleophilic substitution reactions, which in turn make the benzene ring react with other nucleophiles, thereby forming new carbon-carbon bonds, carbon-heteroatomic bonds, etc. For example, when reacting with nucleophiles such as alcohols and amines, bromine atoms can be replaced to form a series of derivatives, which is of great significance in the fields of pharmaceutical chemistry and material chemistry.
Fluorine atoms are extremely electronegative. When introduced into the benzene ring, it will greatly affect the electron cloud distribution of the molecule, enhance the stability of the molecule, and change its physical and chemical properties. For example, it can improve the fat solubility of compounds and affect their biological activities. In the process of drug development, the proper introduction of fluorine atoms can often optimize the efficacy and metabolic properties of drugs.
The existence of difluoromethyl also significantly changes the electronic properties and spatial structure of molecules. Due to its volume and electronic effects, it will affect the interaction between molecules, such as the boiling point and melting point of compounds. In chemical reactions, difluoromethyl can participate in the reaction as a unique structural unit, providing the possibility for the synthesis of novel compounds.
In addition, the chemical properties of the compound are also affected by the electron cloud density of the benzene ring. The conjugate system of the benzene ring gives it certain aromaticity and stability. However, the electron cloud density of the benzene ring is regulated by the substituents at different positions on the benzene ring, thereby affecting the activity and selectivity of the electrophilic substitution reaction. In the electrophilic substitution reaction, the combined action of bromine, fluorine and difluoromethyl determines the position of the new substituent entering the benzene ring.

3-Bromo-5-fluorodifluoromethylbenzene is on the market, and its price range is difficult to determine. The price of 3-bromo-5-fluorodifluoromethylbenzene is determined by many factors, such as the trend of supply and demand, the difficulty of preparation, the quality, and even changes in market conditions.
Looking at the past market conditions, the price of these fine chemicals varies depending on the complexity of the preparation process. If the preparation requires complicated steps, high raw materials, or strict equipment and technical requirements, the price will be high. On the contrary, if the preparation is easier and the raw materials are easily available, the price may be slightly lower.
And the state of supply and demand is also the key. If the market demand for 3-bromo-5-fluorodifluoromethylbenzene is strong and the supply is limited, its price will rise; if the demand is flat and the supply is abundant, the price may decline.
Furthermore, the division of product quality also affects the price. High purity and high quality, the price is often higher than that of ordinary ones. Due to many fields, such as medicine, electronics, etc., the quality of raw materials is extremely high, and it is better to pay high prices for high-quality products.
According to past transactions of similar chemicals, the price may range from a few yuan to several hundred yuan per gram. However, this is only a rough test, and the actual price may change from time to time, and it also varies from supplier to supplier. To know the exact price range, it is also necessary to carefully investigate the current market and consult all suppliers in order to obtain a more accurate estimate.
