2-Cyanopyridine-3-boronic acid

2-Cyanopyridine-3-boronic acid is an important reagent in organic synthesis. It has many unique chemical properties and has a profound impact on the process of organic synthesis.
In terms of its acidity, boric acid partially contains hydroxyl groups, which can give protons under specific conditions and exhibit a certain acidity. However, its acidity is weaker than that of common inorganic acids. This acidic property can be used as a mild acidic catalyst in many organic reactions to help the reaction progress smoothly. For example, some condensation reactions, esterification reactions, etc., it can speed up the reaction rate and improve the reaction efficiency by providing a moderately acidic environment.
Furthermore, the presence of cyanyl groups endows the compound with unique reactivity. The cyanyl group is a strong electron-absorbing group, which can reduce the electron cloud density on the pyridine ring, making the pyridine ring more vulnerable to electrophilic attack. At the same time, the cyanyl group itself can also participate in many reactions, such as hydrolysis reaction can be converted into carboxyl group, reduction reaction can be changed to amino group, etc., which greatly expands the reaction path and derivation possibility of the compound.
From the perspective of spatial structure, the planar structure of the pyridine ring and the spatial distribution of boric acid and cyano groups determine the stereochemical properties of its molecules. This spatial structure factor plays a key role in the process of molecular recognition and interaction with other molecules. For example, in some coordination reactions or supramolecular assembly processes, its unique spatial structure can precisely match specific receptors to achieve specific functions.
In addition, the stability of 2-cyanopyridine-3-boronic acid also affects its chemical properties to a certain extent. Under normal temperature and pressure and conventional storage conditions, the compound is relatively stable. In case of extreme conditions such as high temperature, strong acid, and strong base, its structure may change, triggering various chemical reactions.

2-Cyanopyridine-3-boronic acid is a chemical substance. When storing and transporting, there are several matters that need to be paid attention to.
This substance should be stored in a dry, cool and well-ventilated place. Because of its certain chemical activity, it is afraid of adverse reactions when exposed to moisture or high temperature. Moisture can easily cause its hydrolysis, and high temperature may cause decomposition, which will damage its quality and purity. Therefore, when storing, it is necessary to keep the environment dry and cool, and it can be placed next to the desiccant to avoid the risk of moisture.
When transporting, caution is also required. Packaging must be tight to prevent leakage. If the package is damaged, the substance may interact with the external environment, which will damage itself or endanger the surrounding area. And the transportation process should avoid vibration and collision, because of its stability or affected by such external forces.
Furthermore, this substance may have certain toxicity and irritation. Storage and transportation personnel, in front of appropriate protective equipment, such as gloves, goggles, etc., to prevent contact injury. If inadvertent contact, rinse with plenty of water quickly, and seek medical treatment according to the severity of the injury.
In general, the storage and transportation of 2-cyanopyridine-3-boronic acid requires attention to the environment, packaging and personnel protection to ensure its quality and safety and avoid accidents.

2-Cyanopyridine-3-boronic acid, the price of this product fluctuates in the market, due to various reasons. Looking at the market conditions in the past, its price often varies depending on the price of raw materials, the complexity of the process, and the situation of demand.
If the raw materials are abundant and cheap, the preparation method is simple, and when the supply exceeds the demand, the price may decrease. On the contrary, raw materials are scarce, the process is complicated, and the demand exceeds the supply, and the price will rise.
Past records show that the price per gram may range from tens of yuan to hundreds of yuan. However, the market situation is unpredictable and it is difficult to determine the value. If there is no big difference in recent times, the price per gram may be around 100 yuan. This is just speculation, and the actual price must be consulted with various chemical material suppliers to be sure. Because the chemical industry market is changing rapidly, the opening of new sources, the issuance of new regulations, and the change of times can all cause changes in prices. Therefore, in order to get accurate prices, the current question is the way to go.
