The synthesis methods of 1 - (bromomethyl) -2,3,5 -trifluorobenzene are as follows.
First, it can be started from a suitable aromatic hydrocarbon. The benzene derivative containing the corresponding fluorine substituent is used as the raw material, and the methyl group is introduced on the benzene ring first. This can be achieved by Fu-gram alkylation reaction. Appropriate halogenated methane and catalyst, such as anhydrous aluminum trichloride, are selected. Under suitable reaction conditions, the methyl group is connected to a specific position in the benzene ring. Then, the methyl group is converted to bromomethyl. N-bromosuccinimide (NBS) and an initiator, such as benzoyl peroxide, can be used to carry out a free radical substitution reaction under heating or lighting conditions, so that the hydrogen atom on the methyl group is replaced by the bromine atom to form the target product 1 - (bromomethyl) -2,3,5 -trifluorobenzene.
Second, it can also start from compounds with suitable protective groups. First prepare benzene derivatives with fluorine substitution and the methyl group is protected by suitable protective groups. The choice of protective groups needs to meet the stability under subsequent reaction conditions, and the subsequent is easy to remove. After other reaction steps are completed, the protective groups are removed, and then the bromination reaction is carried out. In this process, the bromination step is similar to the above, and the conversion of methyl to bromomethyl can be achieved by reagents such as NBS.
Third, the Grignard reagent method can also be used. The corresponding Grignard reagent is prepared by using halogenated benzene containing fluoride as the starting material. The Grignard reagent reacts with suitable halogenated hydrocarbons or carbonyl compounds containing bromomethyl, and then undergoes a series of subsequent treatments, such as acidification, to build the carbon skeleton of the target molecule, and then obtains 1- (bromomethyl) -2,3,5-trifluorobenzene. During the reaction process, attention should be paid to the requirements of Grignard reagents for reaction conditions, such as anhydrous and anaerobic

1 - (bromomethyl) - 2, 3, 5 - trifluorobenzene, also an organic compound. Its physical properties are unique and can be described in detail as follows.
First of all, its appearance, at room temperature, this substance is often colorless to light yellow liquid, clear and transparent. If placed in a glass container, the light shines, and it can be seen that it flows brightly, like liquid gold. Its smell has a certain particularity, with a pungent smell. It can be uncomfortable to smell, but its taste is also different from common rancid or aromatic, unique.
As for the boiling point, it has been experimentally determined to be in a specific temperature range. The value of this boiling point is crucial in the field of organic synthesis, because it can be controlled by its distillation, separation and other operations. When heated to the boiling point, the substance gradually changes from liquid to gaseous state, and the molecules break free from each other's attractive forces and drift in space.
Melting point is also an important physical parameter. The existence of its melting point defines the transition limit between solid and liquid states of a substance. In an environment below the melting point, the substance is solid, the molecules are arranged in an orderly and tight manner, and have a fixed shape and volume.
Solubility is also an important property. 1- (bromomethyl) -2,3,5-trifluorobenzene exhibits good solubility in organic solvents, such as common ether, dichloromethane, etc. This property makes it participate in many chemical reactions in a dissolved state, accelerating the reaction process. However, in water, its solubility is not good, because water is a polar solvent, and the polarity of the substance is relatively weak, according to the principle of "similar miscibility", the two are difficult to blend.
In terms of density, compared with water, it has a specific value. When it is placed in a container with water, it can be seen that its stratification phenomenon can be seen, either floating on water or sinking under water, depending on the comparison of its density with water. This density property is quite useful in the separation and identification of substances.
These physical properties are the basis for the understanding and application of 1- (bromomethyl) -2,3,5-trifluorobenzene, and are of great significance in the research and practice of organic chemistry.

1 - (bromomethyl) - 2,3,5 -trifluorobenzene is a chemical substance commonly used in organic synthesis. When storing and transporting, many things must be paid attention to to to ensure safety.
It is active and sensitive to heat, so it should be stored in a cool and dry place. If the temperature is too high, it may cause decomposition and cause danger. In the warehouse, it should be well ventilated to prevent the accumulation of harmful gases. Keep away from fire and heat sources, and strictly prohibit fireworks. This is the important rule of flame prevention and explosion prevention.
This substance is corrosive and can cause burns in contact with the skin and eyes. During transportation, the packaging must be tight. Select suitable packaging materials, such as corrosion-resistant containers, to prevent leakage. If there is leakage, bromomethyl trifluorobenzene can pollute the environment, and bromine ions and fluoride ions may be harmful to soil and water organisms.
In addition, it is a chemical, and relevant laws and regulations must be followed when transporting. Transport personnel should be professionally trained to be familiar with its characteristics and emergency treatment methods. Transport vehicles should also be equipped with corresponding emergency equipment and protective equipment to deal with emergencies.
When storing, it should be stored in categories, and should not be mixed with oxidants, acids, alkalis, etc., because chemical reactions may occur. Check the storage container from time to time. If there is any damage or leakage, it should be dealt with immediately.
In conclusion, 1- (bromomethyl) -2,3,5-trifluorobenzene must be stored and transported in strict accordance with various rules and careful operation to ensure that personnel safety and the environment are not damaged.

The market price of 1- (bromomethyl) -2,3,5-trifluorobenzene is difficult to determine. Its price is influenced by various factors, such as the state of supply and demand, the difficulty of preparation, the quality, and changes in market conditions.
From the perspective of supply and demand, if this product is in high demand in the market, but the supply is scarce, it is like a rare treasure, and the price will increase. On the contrary, if the supply exceeds the demand, it will still be flooded with water, and the price will drop from then on.
When it comes to the production method, if the preparation method is cumbersome, it requires all kinds of rare materials, or goes through many complicated processes, which consume countless manpower, material resources, and financial resources. The cost is high, and the price is also high. If the production method is simple, the cost is controllable, and the price may be close to the people.
The impact of quality should not be underestimated. Those with high quality can meet strict regulations and be used in fine industries, and the price is often expensive; those with inferior quality, or only suitable for ordinary roads, must be low.
Furthermore, the market situation is unpredictable, like a change in the situation. The rise and fall of industries, easier policies, and fluctuations in exchange rates can all affect their prices. The industry is prosperous, demand surges, and prices may rise; policies are tightened, production is limited, and prices may change. Changes in exchange rates affect the purchase of raw materials and the export of products, and indirectly affect their prices.
As for the exact market price, it is necessary to carefully check the chemical raw material trading platform, consult various suppliers, or refer to the market survey report to obtain a more accurate number, but the price is often in change with the above reasons.
