The common synthesis methods of 6-chloropyridine-3-formaldehyde are the key content of chemical synthesis. There are various methods, and each has its own advantages, which must be selected according to the specific situation and needs.
One is the method of using 6-chloronicotinic acid as the starting material. First, 6-chloronicotinic acid and suitable reducing agents, such as lithium aluminum hydride (LiAlH), are used under suitable reaction conditions. In this reaction, lithium aluminum hydride has strong reductive properties, and the carboxyl group (-COOH) of 6-chloronicotinic acid can be reduced to hydroxymethyl (-CH 2O OH) to obtain 6-chloropyridine-3-methanol. Then, 6-chloropyridine-3-methanol is oxidized in a specific solvent with a mild oxidizing agent, such as manganese dioxide (MnO ²), to convert the hydroxymethyl group into an aldehyde group (-CHO), and finally 6-chloropyridine-3-formaldehyde.
The second is the route using 3-cyano-6-chloropyridine as a raw material. After the hydrolysis of 3-cyano-6-chloropyridine, the cyano group (-CN) can be converted into a carboxyl group to obtain 6-chloronicotinic acid. This step needs to be carried out under acidic or alkaline conditions. Then with the above method of using 6-chloronicotinic acid as raw material, the target product is obtained by reduction and oxidation.
There is also a method of synthesizing pyridine derivatives by halogenation, formylation and other series of reactions. First, the pyridine derivatives are halogenated, and chlorine atoms are introduced at suitable positions to obtain 6-chloropyridine derivatives. After that, suitable formylation reagents, such as the combination of DMF (N, N-dimethylformamide) and phosphorus oxychloride (POCl), are selected to formylate 6-chloropyridine derivatives, and aldehyde groups are introduced at 3 positions to obtain 6-chloropyridine-3-formaldehyde.
All synthesis methods have advantages and disadvantages. The method using 6-chloronicotinic acid as raw material has relatively clear steps, but some reagents such as lithium aluminum hydride are highly active and dangerous, so the operation needs to be cautious. Using 3-cyano-6-chloropyridine as raw material, the hydrolysis step may involve more complex reaction conditions to control. Pyridine derivatives are halogenated and formylated. Although the choice of raw materials is diverse, multiple steps may reduce the total yield, and each step needs to be precisely controlled to ensure the purity of the product. In actual synthesis, when considering factors such as raw material availability, cost, controllability of reaction conditions, product purity and yield, the optimal synthesis path is selected.

6-Chloropyridine-3-formaldehyde, this substance is in the market, and its price often changes due to many reasons. The various merchants in the city have different prices because of their quality and quantity.
In the path of ordinary trade, if the purchase quantity is quite small, it is only for small trials or research needs, and its price may be high. Cover the preparation of the process and complexity, the purification technique is difficult, and the small amount of transactions, the operator in order to protect their profits, so the price is high. The price per gram, or up to tens of gold spectrum.
If it is a batch purchase, the industry considers the efficiency of scale and the cost of apportionment, and the price should be reduced. If you buy hundreds of grams or even thousands of grams, the price per gram may be reduced to more than ten gold.
And the supply and demand of the market also affect the price. If there are many people who want it, but there are few suppliers, the price will inevitably rise; if the supply exceeds the demand, the business will sell it quickly, or reduce the price to promote the transaction.
The distance of the place of origin, the cost of transportation, and the difference in time are all related to the price. Produced in distant places, with the addition of freight, the price will be high; when raw materials are scarce and government orders change, the price may also change significantly.
To know the exact price, you should consult the merchants who specialize in the cities, and compare the reports of the various families to understand its current value.
