There are several common methods for the synthesis of 1 - (bromomethyl) -2,3,4,5-tetrafluorobenzene. First, it can be started with 2,3,4,5-tetrafluorobenzoic acid. First, 2,3,4,5-tetrafluorobenzoic acid is reduced in an anhydrous organic solvent such as anhydrous ether or tetrahydrofuran under suitable reaction conditions, in an anhydrous organic solvent such as anhydrous ether or tetrahydrofuran, to obtain 2,3,4,5-tetrafluorobenzyl alcohol. This reaction needs to be operated at a low temperature and strictly anhydrous and anaerobic environment to prevent the failure of the reducing agent and the oxidation of the product. Then, the obtained 2,3,4,5-tetrafluorobenzyl alcohol and hydrobromic acid (HBr) are heated to carry out a substitution reaction in the presence of a catalyst such as sulfuric acid, and the hydroxyl group (-OH) is replaced by a bromine atom (-Br) to obtain 1- (bromomethyl) -2,3,4,5-tetrafluorobenzene. This step requires controlling the reaction temperature and time to avoid side reactions, such as eliminating the reaction to form olefins.
Second, it can be started from 2,3,4,5-tetrafluorobromobenzene. First, it is reacted with metal magnesium (Mg) in anhydrous ether to form Grignard's reagent 2,3,4,5-tetrafluorophenyl magnesium bromide. This reaction needs to be strictly anhydrous, because Grignard's reagent is easily decomposed in contact with water. Subsequently, the Grignard reagent is reacted with paraformaldehyde (Paraformaldehyde) at low temperature to generate the corresponding alcohol intermediate. After hydrolysis, 2,3,4,5-tetrafluorobenzyl alcohol can be obtained. The subsequent steps are the same as the above operation after preparing 2,3,4,5-tetrafluorobenzyl alcohol with 2,3,4,5-tetrafluorobenzyl acid as the starting material, that is, reacting with hydrobromic acid under the action of a catalyst, and finally obtaining the target product 1- (bromomethyl) -2,3,4,5-tetrafluorobenzene.
Or, using 2,3,4,5-tetrafluorotoluene as the raw material. In the presence of light or initiator, it undergoes a radical substitution reaction with N-bromosuccinimide (NBS). NBS is used as a bromine source. Under appropriate initiation conditions, such as azodiisobutyronitrile (AIBN) initiation, the hydrogen atom on the methyl group of toluene is replaced by the bromine atom to generate 1- (bromomethyl) -2,3,4,5-tetrafluorobenzene. This reaction needs to control the reaction conditions, such as light intensity, initiator dosage, etc., to ensure that the reaction mainly occurs on the methyl group and avoid side reactions such as substitution on the benzene ring. Different synthesis methods have their own advantages and disadvantages. In practical application, it is necessary to comprehensively consider factors such as raw material availability, cost, and difficulty in controlling reaction conditions.

Because the substance is prone to chemical reactions when heated, or even the risk of explosion, it must be kept away from heat and fire sources. And humid environment or cause it to deteriorate, which affects its chemical properties.
Furthermore, storage containers should not be ignored. Corrosion-resistant materials, such as special glass or specific plastic containers, must be used to prevent the container from being corroded and causing material leakage. At the same time, the container must be tightly sealed to avoid contact with the air, because it may react with the ingredients in the air.
As for transportation, transportation personnel need to be professionally trained to be familiar with the characteristics of this chemical and emergency treatment methods. Transportation tools should also ensure that they are clean, dry, and have anti-leakage and fire protection devices. During transportation, the traffic must be smooth to avoid violent vibration and collision to prevent packaging damage.
In addition, whether it is storage or transportation, it is necessary to strictly follow relevant regulations and standards. Storage places and transportation vehicles should be posted with obvious warning signs for personnel to identify. At the same time, relevant records should also be detailed, such as storage quantities, time of entry and exit from the warehouse, transportation routes, etc., for traceability and management. If this chemical is leaked, it will pose a serious threat to the environment and personal safety.
