Methyl 5-methoxypyridine-2-carboxylic acid ester, this substance is colorless to pale yellow liquid or crystalline, with a slight special odor. Its melting point is about [X] ° C, because the exact value is affected by molecular structure and interaction. The boiling point is about [X] ° C at a specific pressure, determined by intermolecular forces and vapor pressure. The density is about [X] g/cm ³, reflecting the compactness of the molecule.
This substance is slightly soluble in water because it contains hydrophilic methoxy and pyridine rings, as well as hydrophobic methyl and ester groups. The balance of the two determines solubility; it is soluble in common organic solvents such as ethanol, ethyl ether, and chloroform. Due to the principle of similarity and miscibility, the molecules are similar to organic solvents. < Br >
In terms of stability, it is relatively stable under normal conditions. However, in case of strong oxidants, ester groups may be oxidized; in case of strong acids or bases, hydrolysis reactions will occur. Ester groups hydrolyze under alkaline conditions to form carboxylic salts and alcohols, and under acidic conditions to form carboxylic acids and alcohols. In terms of thermal stability, they may decompose at high temperatures, and the decomposition temperature varies depending on specific conditions.
These physical properties are of great significance for their application in organic synthesis and medicinal chemistry. Knowing solubility can be used to choose suitable reaction solvents and separation methods; understanding stability can determine storage and use conditions, avoid deterioration or cause dangerous reactions, and help them to be used safely and efficiently in various fields.

The synthesis method of methyl-5-methoxypyridine-2-carboxylic acid ester is not directly described in the ancient book "Tiangong Kaiwu", but one or two can be deduced from the ancient chemical technology ideas.
To synthesize this substance, you can first use 5-methoxypyridine-2-carboxylic acid and methanol as raw materials, which are like the main drugs in ancient recipes. In the reaction system, an appropriate amount of catalyst, such as concentrated sulfuric acid, is added, just like the ancient combustion-supporting substance to promote the reaction speed. This catalyst can promote the esterification reaction of the two, just like the primers used fire in ancient times to accelerate the change.
When reacting, temperature control and heating are required, just like the ancients' precise control of heat in alchemy. The temperature should be maintained in a suitable range, about 60-80 degrees Celsius. If it is too high, the raw material may decompose, and if it is too low, the reaction will be slow. And during the reaction process, it needs to be stirred to make the reactants fully contact, just like the ancients reconciled the things, uniform and sufficient.
Another way is to prepare 5-methoxy pyridine first, and then introduce carboxyl and methyl ester groups. Methoxy groups are first introduced into the pyridine ring with suitable reagents and reaction conditions, and then through a series of reactions, such as first introducing carboxyl groups with carbon dioxide, and then esterifying with methanol to form methyl ester groups. This process is like the ancient step by step, in order, each step needs to be handled carefully and cannot be confused.
Furthermore, it can also be obtained from compounds containing the corresponding structure and converted into functional groups. However, no matter what method, it is necessary to fine operation to observe the subtle changes of the reaction, such as the ancient people observing the slight changes in the temperature and adjusting it in a timely manner, in order to successfully prepare methyl-5-methoxypyridine-2-carboxylate.

Methyl-5-methoxypyridine-2-carboxylic acid ester is in the market, and its price range is difficult to determine. The price of this chemical often changes due to multiple reasons.
First, the trend of supply and demand is the main reason. If there are many people who want it, but the supply is small, the price will tend to increase; conversely, if the supply exceeds the demand, the price may drop.
Second, the cost of production is also related. The price of raw materials, the preparation method and energy consumption can all affect its cost. If the price of raw materials is high, or the preparation method is complex and expensive, the price will be high.
Third, the quality is different, and the price is also different. Those with high purity are suitable for areas with strict quality requirements such as medicine and electronics, and the price is often higher than that of ordinary ones.
Fourth, the competition in the market also has an impact. All merchants compete for the market, or adjust the price to occupy the market.
From the perspective of "Tiangong Kaiwu", although there was no such chemical at that time, the price of its words was subject to supply and demand, and the difficulty of production. The price of methyl-5-methoxypyridine-2-carboxylic acid ester in the city, or from a few yuan per gram to hundreds of yuan, is difficult to determine, and must be investigated in detail according to the current market conditions.

Methyl 5-methoxypyridine-2-carboxylic acid ester is one of the organic compounds. Its preservation method is crucial, and it is related to the quality and utility of this substance.
Cover this substance should be placed in a cool, dry and well-ventilated place. A cool environment can avoid chemical changes caused by heat. Under high temperature, it may cause decomposition, polymerization and other reactions, which will damage its inherent properties. A dry place is also indispensable. Due to the easy action of moisture, or the drawbacks such as hydrolysis, it deteriorates. And well ventilated, it can disperse volatile gases that may accumulate in time to prevent its concentration from being too high and causing danger.
Furthermore, it must be kept away from fire sources and oxidants. This material is flammable to a certain extent, and it is easy to burn in case of fire, or even explode, endangering safety. Contact with oxidizing agents or severe oxidation reactions can also damage its structure and properties.
When storing, it should also be contained in a suitable container. It is advisable to use a container with good sealing performance, such as a glass bottle or a specific plastic container, to prevent the intrusion of air, moisture, etc. And the name of this object and relevant warning labels should be clearly marked on the container for identification and protection. In this way, methyl 5-methoxypyridine-2-carboxylate can be properly preserved to maintain its good state for a long time.
