The synthesis method of 5-methylpyridine-3-boronic acid, although the ancient book "Tiangong Kaiwu" does not contain this specific synthesis method, there are many ways for chemical synthesis today.
First, halogenated pyridine can be used as the starting material. First, a suitable halogenated reagent is used to halogenate pyridine at a specific position to obtain halogenated pyridine. Then through a metallization reaction, such as interacting with a lithium reagent, a lithium pyridine intermediate is formed, and then reacts with borate esters. After hydrolysis, the target product 5-methylpyridine-3-boronic acid can be obtained. This process requires fine control of the reaction conditions. The temperature and reagent ratio during halogenation need to be accurate. The anhydrous and oxygen-free environment of the metallization reaction is also the key, otherwise side reactions will easily occur.
Second, pyridine derivatives are used as raw materials and converted into functional groups. For example, the existing functional groups on pyridine are first converted into groups that can react with boron sources, and then boron groups are introduced by organic boron chemical methods. This path requires familiarity with the properties of pyridine derivatives, and the reaction conditions at each step need to be optimized to improve the purity and yield of the product.
Third, transition metal catalysis. Use transition metal catalysts, such as palladium, nickel, etc., to catalyze the reaction of methyl-containing pyridine substrates with boron sources. This method is highly selective and the reaction conditions are relatively mild. However, the selection and dosage of catalysts, the design and screening of ligands are extremely important, which are related to the success or failure of the reaction and its efficiency.
There are various methods for synthesizing 5-methylpyridine-3-boronic acid, each with its own advantages and disadvantages. It is necessary to carefully select the appropriate synthesis path according to actual needs, considering factors such as raw material availability, cost, yield and purity.

5-Methylpyridine-3-boronic acid, the price of this substance in the market often varies due to various reasons. Looking at past market conditions, its price is determined by various factors such as the supply and demand of raw materials, the difficulty of preparation, and the amount required.
In the past, if the raw materials are abundant and the preparation method is simple, its price may tend to be easy. Because the raw materials are abundant, the cost of production can be reduced; the preparation is easy, the consumption of labor and technology is also small, and the price can be close to the people. However, if the raw materials are scarce, or the preparation techniques are complicated, requiring fine skills and heavy capital, the price will rise.
In addition, the demand of the market is also the main reason. If there are too many users, the demand will exceed the supply, and the price will rise; if there are too few people, the supply will exceed the demand, and the price will drop. Furthermore, changes in the current situation, such as government regulations and trade policies, can also cause fluctuations in its price.
To sum up, if you want to determine the current market price of 5-methyl pyridine-3-boronic acid, when you carefully consider the current situation of raw materials, preparation conditions, and market demand, it is more appropriate to consult industry players, brokers, or explore platforms for chemical product trading to obtain detailed prices.

5-Methylpyridine-3-boronic acid is a commonly used reagent in organic synthesis. When storing and transporting, many key matters must be paid attention to.
First word storage. This reagent is quite sensitive to air and moisture, and is highly susceptible to moisture hydrolysis and deterioration. Therefore, it should be stored in a dry, cool and well-ventilated place. It should be placed in a sealed container, preferably protected by inert gases such as nitrogen to isolate air and moisture. If conditions permit, it is more suitable to keep it in the refrigerator. The temperature can be set to 2-8 ° C. This can effectively slow down its possible chemical reactions and prolong the shelf life.
Then transport. During transportation, it is necessary to ensure that the packaging is tight to prevent the package from being damaged and causing the reagent to come into contact with air and moisture. Appropriate packaging materials, such as glass bottles, plastic bottles, etc., should be selected, and the outside of the bottle should be wrapped with cushioning materials, such as foam, cotton, etc., to avoid packaging bursting due to transportation bumps. In view of its sensitivity, the transportation process should be fast to reduce its exposure to adverse environments. In addition, the transportation environment should also be kept dry and avoid high humidity environments.
In short, the key to the storage and transportation of 5-methylpyridine-3-boronic acid is moisture-proof, oxygen-proof, and packaging integrity, so as to maintain its chemical stability and ensure the use effect.
