In terms of density, it has a specific value. Compared with water and other common solvents, it can be judged in the solution system. It is also an important basis for phase separation and other steps in chemical operations.
Solubility cannot be ignored. In organic solvents, such as certain aromatic hydrocarbons, halogenated hydrocarbons, etc., this compound may have good solubility and can be fused with it; however, in water, due to its large difference in molecular polarity from water molecules, its solubility may be poor, just like the insolubility of oil and water.
Volatility, although not very volatile, under appropriate conditions, its molecules can also escape the liquid surface and diffuse in the air. This property requires attention during storage and use. The physical properties of 5- (bromomethyl) -1,2-difluoromethyl-3- (trifluoromethyl) benzene each have their own uses and are an indispensable consideration in chemical synthesis, separation and purification, and product storage.

To prepare 5- (bromomethyl) -1,2 -difluoro-3- (trifluoromethyl) benzene, there are various methods.
First, the benzene derivative containing the corresponding substituent can be started. If there is a suitable benzene ring, which already has difluoromethyl and trifluoromethyl, bromomethyl can be introduced. If a benzene ring compound is introduced into the methyl group before the appropriate position, the benzene derivative containing methyl can be obtained by the alkylation reaction of Fu-g. Halomethane and benzene ring are catalyzed by Lewis acid such as anhydrous aluminum trichloride. After the methyl is brominated, N-bromosuccinimide (NBS) is used as the bromination reagent. In the presence of an initiator such as benzoyl peroxide, light or heat is used to convert the methyl to bromomethyl. This is a free radical substitution mechanism, and the target product can be obtained.
Second, halogenated aromatics can also be used as raw materials. If there are benzene derivatives with halogen atoms in suitable positions, containing difluoro and trifluoromethyl, metal-organic reagents can be used. If the Grignard reagent is first prepared, the Grignard reagent is obtained by reacting magnesium with halogenated aromatics in anhydrous ether or tetrahydrofuran, and then reacting with formaldehyde to introduce hydroxymethyl, and then phosphorus tribromide or hydrobromic acid to convert the hydroxymethyl into bromomethyl, thereby preparing 5- (bromomethyl) -1,2 -difluoro-3- (trifluoromethyl) benzene.
Third, it can also be considered to start from benzoic acid derivatives containing suitable substituents. First, benzoic acid is reduced to benzyl alcohol with reducing agents such as lithium aluminum hydride, and then treated with brominating reagents such as phosphorus tribromide, the hydroxyl group is converted into bromine atoms, and the introduction of bromomethyl is realized, and the All these methods can be tried, each with its own advantages and disadvantages, depending on the actual situation, such as the availability of raw materials, the ease of control of reaction conditions, etc.

5 - (bromomethyl) -1,2 -difluoro-3- (trifluoromethyl) benzene is an organic compound, which must be stored and transported with caution.
When storing, the first choice of environment. When placed in a cool, dry and well-ventilated place, do not approach fire and heat sources. This compound is prone to reaction when heated, or even dangerous, so the temperature should be controlled in a lower range to prevent accidents. Furthermore, it should be separated from oxidants, strong bases, etc. Because of its chemical activity, contact with such substances can easily trigger chemical reactions and endanger safety. The storage container is also critical. It must be made of corrosion-resistant materials and tightly sealed to prevent leakage.
When transporting, there are also many precautions. The packaging must be tight to ensure that it will not be damaged or leaked during transportation. The transportation vehicle must be equipped with corresponding fire protection equipment and leakage emergency treatment equipment. Transportation personnel should also be familiar with the characteristics and emergency treatment methods of this compound, and in case of emergencies, they can quickly and properly dispose of it. In addition, the planning of transportation routes should also be careful to avoid sensitive areas such as water source reserves and densely populated areas to reduce risks.
Therefore, when storing and transporting 5- (bromomethyl) -1,2-difluoro-3- (trifluoromethyl) benzene, pay attention to the above points to ensure safety.
