To prepare 2-pyridine formaldehyde and 3,6-dichloro, the following method can be used.
First take an appropriate pyridine derivative as the starting material. This material should have a modifiable group to introduce chlorine atoms and aldehyde groups. In the reaction system, add suitable chlorination reagents, such as chlorine-containing halogenating agents. Control the temperature, time and reagent dosage of the reaction, so that the chlorination reaction can accurately occur at the 3rd and 6th positions of the pyridine ring to obtain 3,6-dichloropyridine derivatives. This step requires attention to the control of reaction conditions to prevent excessive chlorination or formation of by-products.
Then, for the obtained 3,6-dichloropyridine derivatives, a method that can effectively introduce the aldehyde group is selected. The aldehyde group can be obtained by reacting with a specific organometallic reagent with an aldehyde-containing precursor, or by oxidizing an intermediate containing a specific functional group. During the reaction, it is necessary to pay attention to the pH of the reaction environment, the choice of solvent and other factors to ensure the smooth introduction of the aldehyde group without affecting the existing chlorine atoms on the pyridine ring.
After each step of the reaction, the impurities should be removed by suitable separation and purification methods, such as column chromatography, recrystallization, etc., to obtain a pure target product. In this way, 2-pyridyl formaldehyde and 3,6-dichloro products can be obtained through careful operation in multiple steps.

2-Pyridyl formaldehyde, 3,6-dichloro - There are many key things to pay attention to when storing and transporting this substance.
First of all, discuss storage. Due to its chemical properties, it needs to be placed in a cool, dry and well-ventilated place. This is because moisture can easily cause chemical reactions, which affects quality; high temperature environments may also cause changes such as decomposition. Furthermore, it must be stored separately from oxidants, acids, bases, etc. to prevent dangerous interactions. The storage area should be equipped with suitable containment materials. In case of leakage, it can be handled in time to avoid diffusion.
As for transportation, ensure that the packaging is complete and well sealed. During transportation, the vehicle needs to be protected from sun, rain, and high temperature. Transportation personnel must be familiar with the characteristics of the substance and emergency treatment methods to avoid vibration and impact on the way to prevent package damage. In the event of a leak, corresponding measures should be taken immediately according to its characteristics, evacuate the surrounding personnel, and properly clean up after protection. In short, whether it is storage or transportation, it must be handled with caution according to its chemical properties to ensure safety.
