2-Amino-5-fluoropyridine is also an important compound in organic synthesis. There are many synthesis methods, which are described in detail below.
First, 5-fluoropyridine-2-carboxylic acid is used as the starting material. First, it is co-heated with dichlorosulfoxide. This step is the key step in converting carboxylic acid into acyl chloride, and 5-fluoropyridine-2-formyl chloride can be obtained. Then, an ammonia source is introduced, such as ammonia gas, and the acyl chloride undergoes nucleophilic substitution reaction with ammonia. After this process, 2-amino-5-fluoropyridine can be prepared. The steps of this method are relatively clear, but the acquisition of the starting material 5-fluoropyridine-2-carboxylic acid may require a certain cost and process.
Second, 2-halo-5-fluoropyridine is used as the substrate. Suitable amination reagents can be selected, such as a catalytic system composed of ammonia and copper salts. In this system, halogen atoms are replaced by amino groups to realize the conversion to 2-amino-5-fluoropyridine. The advantage of this approach is that the raw material 2-halo-5-fluoropyridine is relatively easy to obtain, and the reaction conditions are relatively mild, which is easier to operate in an organic synthesis laboratory.
Third, through the construction strategy of pyridine rings. Using appropriate organic small molecules containing fluorine and amino groups as raw materials, pyridine rings are constructed through multi-step reactions. For example, using fluoroenamines and nitrogen-containing nucleophiles, under suitable reaction conditions, through a series of reactions such as cyclization and aromatization, the final product is 2-amino-5-fluoropyridine. Although this method has many steps, it can flexibly adjust the reaction path according to the characteristics of the starting materials to achieve the purpose of synthesis.
All the above synthesis methods have their own advantages and disadvantages. In practical application, it is necessary to make a careful choice based on factors such as the availability of raw materials, the difficulty of controlling reaction conditions, cost considerations, and the purity requirements of the target product.

The price of 2-Amino-5-fluoropyridine in Wuguan City often varies depending on the quality, source and quantity.
Those with excellent quality and high purity will have a higher price; if there are slightly more impurities, the price will be slightly reduced. If the source is a well-known large factory and the output process is strictly controlled, the price will be extraordinary. For those who buy a large quantity, merchants often give discounts, with small profits but quick turnover. This is common sense.
Looking at the past market, if you buy a small amount with a purity of about 98%, the price per gram may be in the tens of yuan. If you buy in bulk, such as hundreds of grams or even kilograms, the price per gram may drop to around ten yuan, or even lower, depending on the specific negotiation.
However, market conditions are volatile, fluctuations in raw material prices, and changes in market supply and demand can affect their prices. Raw materials are abundant, supply exceeds demand, and prices may drop; raw materials are scarce, and demand exceeds supply, and prices will rise. To know the exact price, you must consult merchants and discuss details such as quantity and quality in detail to get an accurate price.

2-Amino-5-fluoropyridine is also a chemical substance. Its storage conditions are related to the stability and safety of this substance, and cannot be ignored.
Cover this substance should be stored in a cool and dry place, away from fire and heat sources. If it is placed in a high temperature or humid place, it may cause its properties to change or cause danger. Because high temperature can promote the rate of chemical reaction, humidity may cause it to be hydrolyzed by moisture and damage its quality.
Furthermore, it needs to be placed in a well-ventilated place. Good ventilation can prevent the accumulation of harmful gases. If this substance evaporates and produces harmful gases, poor ventilation will easily cause its concentration to rise, endangering personal safety and the environment. < Br >
In addition, the storage place should be stored separately from oxidants, acids, bases and other substances, and must not be mixed. The causation of 2-amino-5-fluoropyridine and the above substances may cause violent chemical reactions, causing fires, explosions and other disasters.
In the choice of storage containers, also pay attention to. Use a well-sealed container to prevent it from evaporating and escaping. And the container material must be compatible with 2-amino-5-fluoropyridine and not chemically react with it to ensure its storage stability. < Br >
After taking this product, be sure to reseal the storage container and place it in the original storage place to maintain the stability of its storage environment. In this way, 2-amino-5-fluoropyridine must be properly stored to maintain its quality and avoid its danger.
