The synthesis method of 3-bromo-6- (trifluoromethyl) pyridine-2-formaldehyde can be obtained from many ways. One method is to start with a compound containing a pyridine structure and introduce bromine atoms at the appropriate position in the pyridine ring. It can be achieved by halogenation reaction, such as liquid bromine or specific brominating reagents, under the catalyst such as iron powder or Lewis acid, and react with the pyridine substrate to precisely connect the bromine atoms to the target check point.
Then, trifluoromethyl is introduced on the pyridine ring. This step can be achieved by nucleophilic substitution reaction, using reagents containing trifluoromethyl, such as Grignard reagents such as trifluoromethyl halide, to interact with brominated pyridine intermediates, and regulated by appropriate reaction conditions to successfully integrate trifluoromethyl.
As for the introduction of aldehyde groups, it can be achieved by the conversion of appropriate functional groups. For example, a suitable functional group on the pyridine ring is converted into an aldehyde group through oxidation reaction. If there is an oxidizable alcohol hydroxyl group attached to the pyridine ring, the alcohol hydroxyl group can be oxidized to an aldehyde group by reacting with a mild oxidant, such as chromium trioxide-pyridine complex (Collins reagent), in a suitable solvent and temperature, so as to obtain the target product 3-bromo-6- (trifluoromethyl) pyridine-2-formaldehyde.
Or another way, using different starting materials, first construct the skeleton containing trifluoromethyl and pyridine ring, and then gradually introduce bromine atoms and aldehyde groups, and carefully construct the structure of the target molecule through multi-step reactions, which can also achieve the purpose of synthesis.

3-Bromo-6- (trifluoromethyl) pyridine-2-formaldehyde, which is an important chemical raw material in organic synthesis. During storage, many key matters need to be paid careful attention.
First, temperature control is crucial. This compound is quite sensitive to temperature, and high temperature can easily cause it to decompose and deteriorate. It is suitable to store in a cool place. The optimal temperature range is about 2-8 ° C. Such a low temperature environment can effectively slow down its chemical reaction rate and ensure the stability of chemical properties.
Second, the influence of humidity should not be underestimated. Because of its certain hygroscopicity, humid environment can easily make it hygroscopic, which in turn triggers adverse reactions such as hydrolysis and destroys molecular structure. Therefore, the storage place must be kept dry, and a desiccant can be placed in the storage container to prevent moisture from invading.
Third, the light factor also needs to be considered. Light or cause the compound to undergo photochemical reactions, changing its chemical composition. Therefore, it should be stored in a brown bottle or an opaque container to avoid adverse effects of light.
Fourth, the choice of storage containers should also be particular. Corrosion-resistant materials, such as glass or specific plastic materials, should be selected. Because it contains bromine, fluorine and other elements, or reacts with some metal materials, the container will corrode and affect the purity of the compound.
Finally, the storage area should be well ventilated. Even if the storage conditions are suitable, the compound may still emit a small amount of harmful gases. Good ventilation can discharge harmful gases in time, reduce safety risks and ensure the safety of the storage environment.
In summary, when storing 3-bromo-6- (trifluoromethyl) pyridine-2-formaldehyde, factors such as temperature, humidity, light, storage container and ventilation need to be carefully treated to ensure the quality and stability of the compound.

I look at this question and ask what the market price of 3 - Bromo - 6 - (trifluoromethyl) pyridine - 2 - carbalaldehyde is. However, the market price of this compound is difficult to determine with certainty, and it is affected by many factors.
First, the difficulty of preparation varies. If its synthesis requires complicated steps, rare raw materials or special reaction conditions, the cost will be high, and the price will also rise. Second, the market supply and demand situation is of great significance. If there are many buyers and few suppliers, the price will rise; conversely, if the supply exceeds the demand, the price may fall. Third, the scale of production also affects the price. In large-scale production, the unit cost may be reduced due to the scale effect, and the price is expected to be more affordable.
Looking at the market conditions of the past, the price of such fluorine-containing compounds with heterocyclic structures fluctuates greatly. For ordinary purity, the price per gram may be around tens of yuan to hundreds of yuan; for high-purity special products, the price per gram may reach hundreds of yuan, or even more expensive. However, these are all past prices, and they are only a rough guess. The current market price still needs to be consulted in detail with chemical raw material suppliers, chemical reagent sales platforms, etc., in order to obtain accurate figures.
