6-Methyl-2-pyridinecarboxaldehyde

6 - Methyl - 2 - pyridinecarboxaldehyde is an organic compound with interesting chemical properties. This substance contains a pyridine ring and an aldehyde group. The aldehyde group is active and has the characteristics of a typical aldehyde group.
In terms of oxidation reaction, the aldehyde group is easily oxidized. In case of common oxidants, such as Torun reagent (silver ammonia solution), a silver mirror reaction can occur, and the aldehyde group is oxidized to a carboxyl group to precipitate silver elemental matter. This reaction is often used for qualitative testing of aldehyde groups. In case of Feilin reagent, a similar reaction can also occur, resulting in a brick-red cuprous oxide precipitate.
In the reduction reaction, the aldehyde group can be reduced. Using hydrogen as a reducing agent, in the presence of appropriate catalysts such as nickel and palladium, aldehyde groups can be reduced to alcohol hydroxyl groups to generate 6-methyl-2-pyridyl methanol.
In addition, aldehyde groups can be added to compounds containing active hydrogen. If catalyzed with alcohols under acid, hemiacetals are formed first, and then acetals are formed. React with ammonia and its derivatives to form products containing carbon and nitrogen double bonds.
Because of its aromatic pyridine ring and special electron cloud distribution, the aldehyde groups connected to it are affected by it, and the reaction activity is slightly different from that of ordinary fatty aldodes. The presence of methyl groups on the pyridine ring also affects the electron cloud distribution and spatial structure of the molecule, which in turn affects its chemical properties. For example, the electron cloud density on the pyridine ring increases due to the electron supply effect of methyl groups, which affects the activity and position selectivity of electrophilic substitution reactions to a certain extent.

In the synthesis of 6-methyl-2-pyridine formaldehyde, there are three common methods.
One is to use 6-methyl-2-methylpyridine as the starting material. After mild oxidation, the methyl group is converted to an aldehyde group. Often a mild oxidizing agent, such as manganese dioxide, is combined with sulfuric acid. During the reaction, in a suitable solvent, stirred slowly at controlled temperature, the methyl group in 6-methyl-2-methylpyridine is oxidized and gradually forms an aldehyde group to give 6-methyl-2-pyridine formaldehyde. This process requires careful observation of the reaction process to achieve high yield and purity.
The second is to start with 2-chloro-6-methylpyridine. The Grignard reagent is first prepared, and then reacted with N, N-dimethylformamide (DMF). In anhydrous ether or tetrahydrofuran solvent, 2-chloro-6-methylpyridine and magnesium chips form Grignard reagent, and the activity is greatly increased. Then it interacts with DMF, and after hydrolysis, the chlorine atom is replaced by an aldehyde group to obtain the target product. This way, anhydrous and anaerobic needs to be strictly maintained to prevent the failure of Grignard reagent.
The third is to use 6-methylpyridine-2-carboxylic acid as raw material. First, the carboxylic acid is converted into the corresponding acid chloride, which can be prepared by co-heating with dichlorosulfoxide. Then, after Rosenmund reduction, the acid chloride is hydrogenated to aldehyde under the action of palladium-barium sulfate catalyst. This reduction reaction requires controlling the flow rate and temperature of hydrogen to avoid excessive reduction to alcohol.
All synthesis methods have their own advantages and disadvantages. In practical application, the most suitable method is selected according to the availability of raw materials, cost, and product purity requirements.

6 - Methyl - 2 - pyridinecarboxaldehyde, Chinese name 6 - methylpyridine - 2 - formaldehyde, the price of this substance in the market is difficult to determine. Its price often varies due to various reasons, such as the price of raw materials, the difficulty of production methods, supply and demand conditions, market competition, quality specifications, etc.
In the past, the demand for this substance in the field of organic synthesis has gradually increased, causing its price to fluctuate. If the raw materials are abundant and the production method is energetic, the cost may decrease, and the price will also decrease; on the contrary, the raw materials are scarce and the preparation is difficult, and the price will rise.
Looking at the chemical market, the price of ordinary chemicals ranges from tens of yuan per kilogram to hundreds of yuan. However, the price of 6 - Methyl - 2 - pyridinecarboxaldehyde is often higher due to its special structure and use, or for fine chemicals, pharmaceutical synthesis, etc.
If the quality reaches high purity, it is suitable for high-end pharmaceutical research and development, and the price per gram may be tens of yuan; for industrial grade and slightly lower purity, the price per kilogram may be between hundreds and thousands of yuan. To know the exact price, please consult the chemical raw material supplier for details, subject to real-time market conditions.

6-Methyl-2-pyridyl formaldehyde is also an organic compound. The storage conditions are crucial, related to the stability and change of its quality.
This compound should be placed in a cool and dry place. Covering a cool environment can slow down the movement of its molecules and avoid the risk of rapid reaction and qualitative change due to heat. In a dry place, avoid contact with water vapor. If water vapor immerses it, or causes various reactions such as hydrolysis, its structure will be damaged and its chemical properties will be disturbed.
It must also be kept away from fire and heat sources. 6-Methyl-2-pyridyl formaldehyde, or flammable, in case of fire or hot topic, it may cause the risk of explosion and endanger the surrounding people and things.
When stored, it is appropriate to use a sealed device. Sealed, it can block air, prevent it from being combined with oxygen, and prevent volatilization and loss, and keep its concentration and amount accurate.
And can not be co-stored with oxidizing agents. Oxidizing agent activity, in contact with it, or cause violent reactions, unexpected changes.
Storage requires good ventilation. Good ventilation can disperse harmful gases. If it evaporates, it can be avoided from gathering in one place, reducing the risk of deflagration and protecting the health of the storekeeper.
