6-fluoropyridine-2-carbonitrile

6-Fluoropyridine-2-formonitrile is one of the organic compounds. It has specific chemical properties and has attracted much attention in the field of organic synthesis.
Looking at its chemical activity, due to the strong electronegativity of fluorine atoms and cyanyl groups, fluorine atoms can cause changes in the distribution of molecular electron clouds, which reduce the electron cloud density of pyridine rings, thereby affecting their reactivity. This property makes it easier for hydrogen atoms on pyridine rings to be replaced by nucleophiles in nucleophilic substitution reactions, and the substitution check point is controlled by the localization effect of fluorine atoms and cyanyl groups.

The synthesis method of 6-fluoropyridine-2-formonitrile has been described in many books in the past, and the main one is selected today.
One method is to use 6-fluoropyridine-2-carboxylic acid as the starting material. First, the carboxylic acid is heated with sulfuryl chloride to form an acid chloride. This process needs to be controlled at a moderate temperature, and the product should not be impure due to violent reaction. Acyl chloride is obtained, and then reacts with sodium cyanide in an organic solvent. This organic solvent should be selected from dimethylformamide or the like, because it has good solubility to the reactants and mild reaction conditions. 6-Fluoropyridine-2-formonitrile can be obtained by nucleophilic substitution of the two. However, sodium cyanide is highly toxic, and care must be taken during operation to prevent leakage, and post-treatment must also be careful to prevent residual toxicity.
There are also 2-chloro-6-fluoropyridine as raw materials. This chloropyridine reacts with cuprous cyanide at high temperature and in the presence of appropriate ligands. Ligands such as 1,10-phenanthroline can enhance the activity of cuprous cyanide and promote the reaction. The reaction is carried out in a high-boiling organic solvent such as N-methylpyrrolidone. Strict temperature control and continuous stirring are required to make the reaction uniform. After this nucleophilic substitution reaction, the chlorine atom is replaced by a cyanyl group, and the target product 6-fluoropyridine-2-formonitrile is obtained. However, cuprous cyanide is also toxic, and the operation must be cautious.
Another method is to use pyridine as the starting material and synthesize it through a multi-step reaction. Pyridine is first fluorinated, and the fluorine atom is introduced at the 6 position. This fluorination step or a specific fluorination reagent needs to be used to precisely control the reaction conditions. Due to the active nature of the pyridine ring, the selectivity of the fluorination position needs to be carefully investigated. After obtaining 6-fluoropyridine, it can be obtained through a series of reactions such as formylation, oxidation and dehydration, and finally 6-fluorop Although the steps of this path are complicated, the raw materials are easy to obtain, and if the reaction of each step is properly controlled, it is also a feasible method.
The above synthesis methods have their own advantages and disadvantages. When implementing, it is necessary to comprehensively weigh factors such as raw material availability, cost, difficulty of operation and product purity, and choose the one that is suitable.

6-Fluoropyridine-2-formonitrile is an important compound in organic synthesis. When storing and transporting, many matters must be paid attention to.
First words storage, this compound should be stored in a cool, dry and well ventilated place. Because it is quite sensitive to humidity and temperature, if the environment is humid, it may cause reactions such as hydrolysis, which will damage its quality; if the temperature is too high, it may also cause chemical reactions, and even pose a risk of safety. Therefore, choose a suitable warehouse, control the temperature in a specific range, such as between 15 ° C and 25 ° C, and maintain the humidity at 40% - 60%.
Furthermore, keep away from fire and heat sources when storing. Because of its certain flammability, in case of open flames, hot topics, or combustion or even explosion. In the warehouse, fireworks are strictly prohibited, and fire protection facilities must be complete to prepare for emergencies. At the same time, it should be stored separately from oxidants, acids, alkalis, etc., because 6-fluoropyridine-2-formonitrile and their substances are prone to chemical reactions, resulting in deterioration or danger.
As for transportation, it is necessary to ensure that the packaging is complete and sealed. Packaging materials should have good corrosion resistance and sealing to prevent leakage during transportation. During transportation, the driving should be stable to avoid violent vibration and impact to prevent package damage. Transportation vehicles should also be equipped with corresponding varieties and quantities of fire protection equipment and leakage emergency treatment equipment. If a leak occurs during transportation, drivers and passengers must immediately take emergency measures to evacuate the surrounding people, strictly prohibit the proximity of fire, and quickly report to the relevant departments for proper handling.
In summary, the storage and transportation of 6-fluoropyridine-2-formonitrile must be handled with caution and in strict accordance with regulations to ensure the safety of personnel and the integrity of goods.

6-Fluoropyridine-2-formonitrile, the price of this product is uncertain in the market, and it often varies due to many reasons.
Looking at past market conditions, the change of its price is related to the source of raw materials, the difference in production methods, and the situation of demand and supply. If the raw materials are easily available and abundant, the preparation method is simple and efficient, and there are few people in the market, the price may tend to be easy. On the contrary, if the raw materials are rare and difficult to produce, and there are many people seeking, the price will be high.
In the past, due to the sharp decrease in the production of raw materials, the demand and supply of raw materials were unbalanced, and the price was unstable, and the increase was quite huge. At that time, the method of preparation was not refined, which also added to the reason for its price increase. After that, the production of raw materials gradually resumed, and new methods of production also came out, and the supply gradually became sufficient. The demand was met, and the price gradually dropped and became stable.
However, the market is unstable, and the current price is also controlled by all aspects of the present. The global situation and economic state are all related to the fluctuation of prices. Either due to changes in trade, or due to changes in the price of energy, the price can fluctuate. And in different places, due to the difference in transportation fees and taxes, the price is also different. < Br >
Therefore, if you want to know the exact price, you should carefully observe the market conditions, visit various merchants, and observe their demand and supply before you can know the price of the market.
