To prepare methyl 2-methylpyridine-3-carboxylic acid ester, the following ancient method can be followed.
Take 2-methylpyridine as the starting material first, and react with a specific reagent in an appropriate reactor, with the assistance of a suitable temperature and catalyst. For example, it can be acylated with a suitable acylating reagent under mild heating. In this process, the reaction temperature and time need to be precisely adjusted to prevent side reactions from breeding.
After the acylation reaction is completed and the intermediate product is obtained, the next step of conversion is carried out. The intermediate product is placed in another reaction system, and a suitable esterification reagent, such as methanol and an appropriate amount of concentrated sulfuric acid, is added as a catalyst to promote the esterification reaction under the condition of heating and reflux. This step requires close monitoring of the reaction process, and the use of thin-layer chromatography and other means to determine whether the reaction is complete in a timely manner.
After the reaction is completed, the reaction solution needs to go through a series of post-treatment steps. First, the target product is extracted with an appropriate solvent to separate the impurities. The extraction solution is dried with anhydrous sodium sulfate to remove the moisture. Subsequently, the solvent is removed by the method of reduced pressure distillation, and the fraction within a specific boiling point range is precisely collected. This fraction is methyl 2-methylpyridine-3-carboxylate. Throughout the process, the reaction conditions must be carefully controlled, and each step requires careful operation to obtain high-purity products.

Methyl-2-methylpyridine-3-carboxylic acid ester is one of the organic compounds. When storing this substance, many matters need to be carefully paid attention to.
First, pay attention to the ambient temperature of storage. This compound is very delicate, and if the temperature is too high, it may cause its chemical properties to deteriorate and cause decomposition or deterioration. Therefore, it should be stored in a cool place, preferably not exceeding 25 ° C, so as to ensure the stability of its chemical structure.
Second, the control of humidity is also the key. High humidity environment is easy to make methyl-2-methylpyridine-3-carboxylic acid ester absorb moisture, or involve adverse reactions such as hydrolysis. It must be placed in a dry place, and a desiccant can be used to maintain the dryness of the surrounding environment and avoid excessive contact with water vapor.
Third, storage away from light cannot be ignored. Under light, especially direct light, it may stimulate the chemical reaction of this compound and damage its quality. Therefore, it is advisable to choose opaque containers, such as brown glass bottles, to store them, and store them in a dark place to prevent light disturbance.
Fourth, storage places must avoid oxidants, acids, bases and other substances. When methyl-2-methylpyridine-3-carboxylic acid esters encounter such chemicals, they are prone to violent reactions and cause dangerous life. Be sure to store in partitions to avoid the possibility of contact with each other.
Fifth, the storage container must ensure that it is well sealed. To prevent the compound from evaporating and escaping, not only to maintain its own content stability, but also to avoid harm to the surrounding environment and human health. And on the container, the name, characteristics, storage date and other information of the compound should be detailed for future access and management.
When storing methyl-2-methylpyridine-3-carboxylate, care must be taken in terms of temperature, humidity, light, material contact and container sealing, so as to maintain its quality and safety for a long time.

The price of methyl-2-methylpyridine-3-carboxylic acid ester is difficult to determine in the market. The price of the cover often changes due to various reasons, and it cannot be generalized.
First, the price of raw materials has a great impact. If the price of all raw materials required for the preparation of methyl-2-methylpyridine-3-carboxylic acid esters rises and falls, the price of the finished product will also fluctuate. If the raw materials are abundant and the supply is abundant, the price may decline; conversely, if the raw materials are scarce and difficult to purchase, the price will rise.
Second, the method of preparation is also important. Different preparation processes have different costs. A refined method can save materials and time, reduce its cost, and the price is also cheap; if the process is complicated and expensive, the price will be high.
Third, the supply and demand of the city is the key. If the market has strong demand for this product, but the supply is limited, the demand exceeds the supply, and the price will rise; if the demand is low, the supply is excessive, and the supply exceeds the demand, the price will fall.
Fourth, changes in the current situation also have an impact. Such as tax increases and decreases, easier government orders, and smooth transportation, etc., can all make the cost different, thus causing the price to change.
Therefore, in order to know the exact market price of methyl-2-methylpyridine-3-carboxylic acid ester, it is necessary to carefully review the raw material market, preparation process, market supply and demand and the situation of the situation, and comprehensively weigh it before obtaining a more accurate price. And the market is fickle, and the price is often changing, so keep an eye on its dynamics.
