Looking at its appearance, under room temperature and pressure, 4-methoxypyridine-2-formaldehyde often appears light yellow to yellow solid. This morphological feature is convenient for researchers to make preliminary identification and cognition at the visual level.
When it comes to the melting point, it is about 58-62 ° C. As one of the important physical properties of substances, the melting point can not only be used for purity determination, but also has great significance for the study of its state change in a specific temperature environment. When the temperature gradually rises to the melting point range, the substance slowly melts from the solid state to the liquid state. This process has a profound impact on many chemical experimental steps involving heating or temperature control.
In terms of boiling point, it is about 273.5 ° C. The boiling point reflects the temperature conditions required for the transformation of a substance from a liquid state to a gas state. Knowing this value is indispensable for accurately controlling the temperature and realizing the effective separation and purification of substances in experimental operations such as distillation and separation.
Solubility is also a key physical property. 4-methoxypyridine-2-formaldehyde is soluble in common organic solvents such as ethanol, dichloromethane, etc. This solubility property facilitates its use as a reactant or intermediate in organic synthesis reactions. Since many organic reactions need to be carried out in a solution environment, good solubility can ensure that the reaction occurs fully and efficiently.
In addition, the substance has a certain volatility. Although the volatility is not extremely strong, it is still necessary to pay attention to its volatilization loss in an open system or a higher temperature environment to avoid interference with the accuracy of the experimental results. At the same time, its odor has a certain particularity. Although it is difficult to describe accurately, it can be sensed by olfaction during experimental operation, which is also one of the auxiliary basis for identifying the substance.
All the physical properties are interrelated, and together they construct the material characteristics of 4-methoxypyridine-2-formaldehyde, which lays a solid foundation for its research, synthesis and application in the field of organic chemistry.

The synthesis methods of 4-methoxypyridine-2-formaldehyde have existed in ancient times, and there are many kinds. The following are the common synthesis paths.
First, 4-methoxypyridine-2-carboxylic acid is used as the starting material. This carboxylic acid can be converted into 4-methoxypyridine-2-methanol by reduction reaction. Usually with strong reducing agents such as lithium aluminum hydride, in a low temperature and anhydrous environment, careful operation can reduce the carboxyl group to the alcohol hydroxyl group. Then, 4-methoxypyridine-2-methanol is further oxidized by a mild reaction, such as manganese dioxide or PCC (pyridine chlorochromate salt) as an oxidizing agent. In a suitable organic solvent, the alcohol can be oxidized to an aldehyde to obtain 4-methoxypyridine-2-formaldehyde.
Second, a suitable pyridine derivative is used as the starting material, and the methoxy group is synthesized by introducing a methoxy group and an aldehyde group. For example, a compound with a suitable substituent at a specific position on the pyridine ring is selected, and the methoxy group is first introduced by a nucleophilic substitution reaction. After the methoxy group is successfully introduced, the specific reaction conditions are then used, such as the Vilsmeier-Haack reaction. In this reaction, N, N-dimethylformamide (DMF) and phosphorus oxychloride (POCl
Third, the coupling reaction strategy of metal catalysis is adopted. First, pyridine derivatives with suitable functional groups, such as halogenated pyridine derivatives, and borate esters or boric acid derivatives containing methoxy groups, are prepared under the action of palladium and other metal catalysts. Suzuki coupling reaction can introduce methoxy groups into the pyridine ring. After that, the aldehyde group is introduced into the 2-position of the pyridine ring through a specific reaction, such as the reaction of metal-organic reagents with carbon dioxide, and then reduction steps, 4-methoxypyridine-2-formaldehyde can also be obtained.
Synthesis methods have their own advantages and disadvantages, and need to be carefully selected according to the actual situation, such as the availability of raw materials, the difficulty of reaction conditions, and the high cost.

4-Methoxypyridine-2-formaldehyde is a key raw material for organic synthesis. During storage and transportation, many important things must be paid attention to.
First of all, store this substance in a cool, dry and well-ventilated place. Because it is more sensitive to heat, high temperature is easy to decompose or deteriorate, so the warehouse temperature should be controlled between 15-25 ° C. Furthermore, be sure to keep away from fire and heat sources to prevent the risk of fire. Because it has a certain chemical activity, it needs to be stored separately from oxidants, acids, bases, etc., and must not be mixed to avoid dangerous chemical reactions. At the same time, the storage area should be equipped with suitable containment materials, and if there is any leakage, it can be dealt with in time.
As for transportation, ensure that the packaging is complete and sealed. Transportation vehicles should be equipped with corresponding fire equipment and leakage emergency treatment equipment. During transportation, it should be protected from exposure to the sun, rain, and high temperature. When driving, follow the prescribed route and do not stop in densely populated areas and residential areas. When loading and unloading, the operation must be light and light to prevent damage to packaging and containers.
In short, the storage and transportation of 4-methoxypyridine-2-formaldehyde requires careful treatment at every step, and strict compliance with relevant procedures to ensure safety and avoid accidents.

4-Methoxypyridine-2-formaldehyde, the price of this substance in the market is difficult to determine. The change in its price depends on multiple ends.
One is related to the raw materials used to make it. If the various raw materials required are easy to obtain and affordable, and the market is abundant, the cost of making 4-methoxypyridine-2-formaldehyde will be reduced, and its price in the market will also be reduced. On the contrary, if the raw materials are rare, difficult to find, or available or not, the price will be high.
Second, depending on the production method. The subtle and efficient method can save labor and time, reduce the cost of the system, and the price may be cheap. If the method of making is clumsy, labor and materials are expended, and the cost is increased, the price will be difficult to lower.
Third, the supply and demand of the city is also the main reason. If there are many people who need this 4-methoxypyridine-2-formaldehyde, and the demand is too high, the price will rise; if the city's stock is full and the supply exceeds the demand, the price will drop.
Fourth, it is related to the competition of the city. If there are many businesses here, and the competition is fierce, each wants to get customers at the best price, and the price may be lower. If there are few people in the city, and they are almost exclusive, the price will be determined by the other party, or they can be haute couture.
And there are various foreign affairs, such as political regulations, tax changes, transportation costs, etc., all of which are related to the price. Therefore, if you want to know the market price of 4-methoxypyridine-2-formaldehyde, you must look at all these reasons, and pay attention to the dynamics of the market from time to time, before you can get a more accurate price.
