The synthesis methods of 6-methoxypyridine-3-boronic acid are many in ancient books. The first method is to use 6-methoxypyridine-3-halo as the starting material, in an inert gas protective atmosphere, react with organometallic reagents, such as n-butyl lithium, at low temperature to form the corresponding lithium reagent, and then react with borate esters, such as trimethyl borate, etc., and hydrolyze to obtain 6-methoxypyridine-3-boronic acid. This process requires strict temperature control to avoid side reactions. < Br >
Second, take 6-methoxypyridine as the starting material, and in the presence of suitable catalysts, such as transition metal catalysts, such as palladium catalysts, and boron-containing reagents, such as pinacol boranes, in suitable solvents, heat the reaction. This reaction requires the selection of suitable ligands to increase the activity and selectivity of the catalyst, so as to promote the smooth progress of the reaction. After subsequent treatment, the target product can also be obtained.
There are also those who use 6-methoxy-3-nitropyridine as raw material. The nitro group is first reduced to an amino group, and then reacted with a boron-containing reagent through diazotization to obtain 6-methoxy pyridine-3-boronic acid. This route step is slightly complicated, but if the raw material is convenient, it is also a method. Each method has its advantages and disadvantages, and it needs to be used according to the actual situation, such as the availability of raw materials, cost, yield, etc.

6-Methoxypyridine-3-boronic acid is an important compound in organic chemistry. Its physical and chemical properties are particularly critical, and are related to the process of many chemical synthesis and reactions.
When it comes to physical properties, this compound is usually white to white solid powder under normal conditions, which is caused by the aggregation state caused by the intermolecular forces. Its melting point and boiling point are also characterized by thermal properties. Generally speaking, the melting point is within a specific temperature range, which is determined by the structure of the molecule and the intermolecular interactions such as hydrogen bonds and van der Waals forces. Higher intermolecular forces often lead to higher melting points, and more energy is required to overcome these forces to melt the substance.
As for chemical properties, the boric acid group of 6-methoxypyridine-3-boronic acid confers its unique reactivity. The boric acid group has Lewis acidity and can coordinate with electron-rich molecules or ions. This property is often used to construct complex organic structures. In organic synthesis reactions, it often participates in the Suzuki-Miyaura coupling reaction. In this reaction, the boric acid group forms a carbon-carbon bond with halogenated aromatics or olefins under the action of metal catalysts such as palladium catalysts to achieve effective molecular construction.
Furthermore, its methoxy group and pyridine ring also affect its chemical properties. Methoxy groups can increase the electron cloud density of the pyridine ring, which in turn affects the activity and selectivity of electrophilic substitution reactions on the pyridine ring. The nitrogen atom of the pyridine ring can be used as a check point to form complexes with metal ions, which has potential applications in the fields of catalytic chemistry and materials chemistry.
In addition, the solubility of 6-methoxypyridine-3-boronic acid in different solvents is also an important property. Its solubility is related to the polarity of the molecule. The moderate polarity makes it have a certain solubility in some polar organic solvents such as dichloromethane, N, N-dimethylformamide, etc. This property facilitates its dissolution and reaction as a reactant or intermediate in organic synthesis operations.

The price of 6-methoxypyridine-3-boronic acid in the market is difficult to determine. Due to various reasons, its price often changes.
In the past, the price of chemical raw materials often changed due to the balance of supply and demand, the price of raw materials, the progress of technology, and changes in policies and regulations. 6-methoxypyridine-3-boronic acid, if there are many people who want it, but the supply is small, the price will be higher; if the production capacity is greatly increased, and the demand is small, the price may drop.
The price of raw materials has a significant impact on the price of finished products. If the price of the raw material required to make this product increases, in order to ensure its profit, its price will also increase; conversely, the price of the raw material decreases, or the price of the finished product decreases.
The improvement of the process can also change its price. If new techniques can increase the yield and reduce energy consumption, the cost of this product may decrease, and the price may also decrease.
Changes in political regulations are also a major reason. If environmental protection regulations are strict, the cost of producing this product will increase and the price will also increase.
From this perspective, if we want to determine the market price of 6-methoxypyridine-3-boronic acid, we must carefully consider the current supply and demand, the price of raw materials, the technological environment and the shape of political regulations. Generally speaking, the price may be between a few yuan and a few dozen yuan per gram, but this is only an approximate number. The actual price is still subject to the current market situation.

6-Methoxypyridine-3-boronic acid, when storing and transporting, there are several ends to pay attention to.
The nature of this product is related to its storage and transportation. Its chemical structure contains boron and pyridine, methoxy and other groups, so it has certain chemical activity. When storing, it should be placed in a dry place first. Because it has a certain sensitivity to water, if the environment is humid, or it may cause hydrolysis, it will damage its purity and quality. And it needs to be protected from heat, high temperature or cause it to decompose and deteriorate. The storage place should be well ventilated to prevent the accumulation of harmful gases.
During transportation, it should not be ignored. The packaging must be tight to prevent it from leaking due to collision. Select suitable packaging materials, which can withstand certain external impact and chemical attack. The means of transportation should also be kept in a dry and cool environment, protected from direct sunlight and heat sources.
In addition, this product may be toxic and irritating. When storing, the operator should prepare protective equipment, such as gloves, goggles, masks, etc., to avoid contact with the skin, eyes, and respiratory tract. In case of inadvertent contact, rinse with plenty of water as soon as possible and seek medical attention as appropriate.
Store 6-methoxypyridine-3-boronic acid, and be careful in terms of environment, packaging, and personnel protection, so as to ensure its quality and transportation safety.
