There are several common methods for the synthesis of 2-cyano-6-fluoropyridine as follows.
First, 2-chloro-6-fluoropyridine is used as the starting material. In a suitable reaction vessel, put 2-chloro-6-fluoropyridine, add cyanide reagents, such as cuprous cyanide, etc. Using N, N-dimethylformamide (DMF) as a solvent, under heating and stirring conditions, the nucleophilic substitution reaction occurs. In this reaction process, the cyano negative ion attacks the carbon atom attached to the chlorine atom of 2-chloro-6-fluoropyridine, and the chloride ion leaves, then 2-cyano-6-fluoropyridine is formed. After the reaction, the pure product can be obtained by extraction, washing, drying, column chromatography and other separation and purification methods.
Second, 6-fluoropyridine-2-formic acid is used as the starting material. First, 6-fluoropyridine-2-formic acid is reacted with dichlorosulfoxide and other reagents to undergo acyl chloride reaction to obtain 6-fluoropyridine-2-formyl chloride. Then 6-fluoropyridine-2-formyl chloride is reacted with ammonia to generate 6-fluoropyridine-2-formamide. Finally, in the presence of dehydrating agents such as phosphorus pentoxide, heat dehydration can be performed to obtain 2-cyano-6-fluoropyridine. After the reaction is completed, corresponding separation operations are also required to obtain high-purity products.
Third, 2,6-difluoropyridine is used as the raw material. It is cyaninated with zinc cyanide and other cyanidation reagents under certain temperature and pressure conditions in the presence of palladium catalyst and suitable ligands in suitable solvents. This reaction uses the mechanism of transition metal catalysis to realize the replacement of fluorine atoms by cyanyl groups, thereby generating the target product 2-cyano-6-fluoropyridine. After the reaction is completed, regular post-processing procedures, such as filtration, concentration, separation, etc., can obtain pure 2-cyano-6-fluoropyridine.

2-Cyano-6-fluoropyridine is a chemical commonly used in organic synthesis. When storing and transporting this substance, many key points should be paid attention to.
First safety protection. Because of its toxicity and irritation, it is vulnerable to human contact. The storage place must be well ventilated. Workers should wear protective clothing, gloves and goggles when working to prevent direct contact with the skin and eyes, and the operation should be carried out in a fume hood to prevent inhalation of its volatile gases.
Secondary storage conditions. It should be placed in a cool, dry place, away from fire and heat sources. This substance is exposed to heat or open flame, or there is a risk of combustion and explosion. It is sensitive to air and moisture, so it needs to be sealed and stored to avoid deterioration caused by contact with air and moisture, which will affect the use effect.
In terms of transportation, it should be implemented in accordance with the relevant regulations on the transportation of hazardous chemicals. Select appropriate packaging materials to ensure that the packaging is complete during transportation and there is no risk of leakage. Transportation vehicles should also be equipped with corresponding fire protection equipment and leakage emergency treatment equipment. Transportation personnel must undergo professional training and be familiar with transportation precautions and emergency disposal methods.
In short, the storage and transportation of 2-cyano-6-fluoropyridine requires safety. Strictly follow relevant specifications and operating procedures to effectively prevent accidents and ensure the safety of personnel and the environment.

The market price of 2-cyano-6-fluoropyridine is difficult to determine. The price of this compound often changes due to various factors, just like the weather, geographical location, and personnel, which change rapidly.
Looking at the past, the price of this compound was determined by the source of raw materials, supply and demand conditions, and the ingenuity of the process. If the raw materials are abundant and easy to obtain, and the process is refined, the cost of its production may decrease, and the price will also fall; on the contrary, if the raw materials are scarce and the process is complicated, the price will rise.
In addition, the supply and demand relationship of the market has a huge impact on its price. If there are many applicants, and there are few suppliers, the price will rise; if there are few applicants, and there are many suppliers, the price will fall.
Furthermore, the difference in geography also leads to price differences. In the prosperous capital of Dayi, due to convenient logistics, the market is wide, and the price may be relatively stable; in remote places, due to the difficulty of transportation and the stagnation of trade, the price may be high.
Moreover, the market situation is fickle, just like the change of the situation. Yesterday's price is not the current price; today's price is not the clear price. Therefore, in order to know its exact price, we should carefully examine the current market situation, consult the industry, or explore various trade places, in order to obtain a more accurate number.
