The chemical synthesis of 2-cyano-5-fluoropyridine has several ways in ancient times. First, 5-fluoropyridine-2-carboxylic acid can be used to react with ammonia to form 5-fluoropyridine-2-formamide first, and then dehydrated to form 2-cyano-5-fluoropyridine through the action of dehydrating agents such as phosphorus pentoxide. This process requires controlling the reaction temperature and the amount of reagents to prevent side reactions.
Another method is to use 5-bromo-2-cyanopyridine as raw material, with the help of fluorinating reagents, such as potassium fluoride, cesium fluoride, etc., in a suitable organic solvent, in the presence of a catalyst, nucleophilic substitution occurs, bromine is replaced by fluorine, and the target product 2-cyano-5-fluoropyridine is obtained. However, this reaction requires attention to the selection of solvents, which can dissolve the raw materials and reagents, and does not interfere with the reaction. The type and dosage of catalysts also affect the reaction efficiency and selectivity.
In addition, 2-chloro-5-fluoropyridine can be used to start with cyanide reagents, such as cuprous cyanide, under appropriate reaction conditions, through nucleophilic substitution, chlorine atoms are replaced by cyano groups to generate 2-cyano-5-fluoropyridine. In this reaction, the activity of the cyanide reagent and the control of the reaction conditions are very critical, and it is necessary to prevent the decomposition of the cyanide reagent or other side reactions.
All synthesis methods have their own advantages and disadvantages. According to actual needs, considering the availability of raw materials, cost, difficulty of reaction conditions, product purity and other factors, the appropriate method is selected to synthesize 2-cyano-5-fluoropyridine.

The price of 2-cyano-5-fluoropyridine in the market is difficult to determine. This change in price depends on many reasons.
First, the price of raw materials has a lot to do with it. If the price of raw materials for making 2-cyano-5-fluoropyridine rises and falls irregularly, the price of finished products will also change accordingly. The origin and output of raw materials, the trend of supply and demand, and the disturbance of natural and man-made disasters can all cause the price of raw materials to vary.
Second, the method of preparation is also the key. A subtle and simple method can reduce costs, and the price may be close to the people; a difficult and expensive method, the cost will be high, and the price will be not cheap. The rise of new technologies, if it can reduce energy consumption, increase output, and improve purity, the price may change significantly.
Third, the supply and demand of the city is the orientation of the price. If there are many seekers and few suppliers, the price will rise; if the supply exceeds the demand, the price will be depressed. The rise and fall of the industry and the exploration of new uses can change the trend of supply and demand.
Fourth, regulation and taxation also have an impact. The tightness of regulations and the increase or decrease of taxes can all add to the cost, resulting in the increase or decrease of prices.
To sum up, in order to know the exact price of 2-cyano-5-fluoropyridine, it is necessary to carefully examine the raw materials, production methods, supply and demand, and regulatory matters. However, the market situation changes, and the price is also variable. Only when you pay attention can you get close to the real price.
