3-bromo-2-(bromomethyl)-6-(trifluoromethyl)pyridine

To prepare 3-bromo-2- (bromomethyl) -6- (trifluoromethyl) benzene, the following ancient method can be used:
First take an appropriate amount of p-trifluoromethyl styrene and place it in a clean reaction vessel. Add an appropriate amount of carbon tetrachloride as a solvent to fully disperse the reactants. In this mixed system, slowly drop the carbon tetrachloride solution of bromine, and at the same time, precisely control the temperature in an ice-water bath to keep the temperature of the reaction system constant at about 0 ° C. During this process, pay close attention to the reaction phenomenon, and see the gradual change of the color of the solution. Bromine and p-trifluoromethylstyrene undergo an addition reaction, the double bond is broken, and bromine atoms are added to both ends of the double bond to obtain the intermediate 1,2-dibromo-1- (4-trifluoromethylphenyl) ethane.
Then, carefully transfer the resulting intermediate to another reaction vessel. Add an appropriate amount of N-bromosuccinimide (NBS) and use benzoyl peroxide as the initiator. The reaction system needs to be carried out under light conditions and can be irradiated by ultraviolet light. Under these conditions, bromine atoms in NBS selectively replace hydrogen atoms on methyl groups connected to the benzene ring in the intermediate. During the reaction, the reaction process is monitored regularly. After the reaction is completed, it is separated and purified by methods such as column chromatography, using silica gel as the stationary phase and a suitable eluent to collect the fractions containing the target product, remove impurities, and finally obtain pure 3-bromo-2- (bromomethyl) -6- (trifluoromethyl) benzene.
In this synthesis method, the conditions of each step need to be strictly controlled. The amount of solvent, the proportion of reactants, temperature and light conditions all have a great impact on the reaction result. When operating, be careful and meticulous to obtain satisfactory yield and purity.

Its abundant hydroxyl groups can be used as a check point for modification, and its physicochemical properties can be changed by chemical modification to meet different application requirements.

For 3-hydroxy- 2 - (hydroxymethyl) -6 - (trihydroxymethyl) pyridine, pay attention to many matters during storage and transportation.
The first priority is its stability. This compound contains many hydroxyl groups, has strong hydrophilicity, and is easy to absorb moisture. If the storage environment humidity is quite high, it may cause moisture and agglomeration, which will affect the quality and performance. Therefore, the storage place must be dry, and a desiccant can be placed next to it to keep the environment dry.
Secondary and temperature factors. Excessive temperature may cause the compound to decompose and deteriorate, causing its chemical structure and properties to change. Therefore, it should be stored in a cool place, protected from direct sunlight, to prevent temperature fluctuations from damaging it. When transporting, you should also pay attention to the temperature changes around you. In hot seasons, you may need to take cooling measures.
Furthermore, this substance may react with certain substances. During transportation and storage, you should avoid contact with strong oxidants, strong acids, strong bases and other substances. Because of its high hydroxyl activity, it may react violently when encountering the above substances, endangering safety. When storing, it should be placed separately from such substances, marked and isolated.
In addition, packaging is also crucial. Packaging materials need to have good sealing to prevent moisture and air from entering. At the same time, they must be able to withstand certain external forces to protect the compounds from damage during transportation bumps. The name, nature, precautions, etc. should be clearly marked on the outside of the package to facilitate identification and handling.
The handling process should be handled with care to avoid violent vibration and collision to prevent the package from breaking and causing compound leakage. Once a leak occurs, proper handling measures should be taken immediately according to its characteristics to avoid polluting the environment and endangering human health.
