The preparation method of 2-aminopyridine-4-carboxylic acid has been recorded in the past, and now it is detailed for you.
One method is to use pyridine-4-carboxylic acid as the starting material. First, pyridine-4-carboxylic acid and appropriate nitrifying reagents, such as concentrated nitric acid and concentrated sulfuric acid mixed acid, are nitrified at a specific temperature and reaction time to obtain 2-nitropyridine-4-carboxylic acid. This step requires attention to temperature control to prevent side reactions from occurring. Then, the 2-nitropyridine-4-carboxylic acid is reduced with a suitable reducing agent, such as a combination of iron powder and hydrochloric acid, or hydrogen in the presence of a palladium-carbon catalyst, and the nitro group can be converted into an amino group to obtain 2-aminopyridine-4-carboxylic acid.
Another method is to use 2-halopyridine-4-carboxylic acid as a raw material. The halogen atom can be chlorine, bromine, etc. Let the 2-halopyridine-4-carboxylic acid react with an ammonia source, such as liquid ammonia or ammonia water, under appropriate temperature and pressure conditions with the help of a phase transfer catalyst. The phase transfer catalyst can promote the reaction between the two phases to proceed more smoothly and improve the reaction efficiency. After this reaction, the halogen atom is replaced by an amino group to achieve the purpose of preparing 2-aminopyridine-4-carboxylic acid.
In addition, there are also those who use pyridine as the starting material. First, the pyridine is substituted at a specific position, the carboxyl group and other groups that can be converted into amino groups are introduced, and then a series of reaction steps are carried out to gradually achieve the preparation of the target product. However, this approach is complicated, and the reaction conditions of each step need to be carefully adjusted to ensure the purity and yield of the product.
All kinds of preparation methods have their own advantages and disadvantages. In practical application, the choice should be made according to various factors such as specific needs, availability of raw materials, cost considerations, and operability of reaction conditions.

What I am asking you is about the market price of 2-aminopyridine-4-carboxylic acid. However, the market price of this compound is difficult to sum up. The price often changes due to many factors.
The first to bear the brunt is the cost of raw materials. If the raw materials required for the synthesis of this acid are difficult to obtain and the price is different, it will affect the cost of 2-aminopyridine-4-carboxylic acid, which in turn affects its market price.
Furthermore, the quality of the production process is also the key. Sophisticated craftsmanship may improve output efficiency, reduce energy consumption, resulting in lower costs and lower prices. If the process is crude and the cost is high, the price will not be low.
The state of market supply and demand is also an important variable in price. If the market demand for this acid is strong and the supply is limited, the price will rise; on the contrary, if the supply exceeds the demand, the merchant may have to lower the price in order to sell its goods.
In addition, the different manufacturers also make the price different. Well-known large factories, because of their reputation and quality, may have relatively high prices; while small factory products, although the price may have advantages, but the quality may be difficult to compare with large factories.
Looking at the state of the market in the past, the price of this acid fluctuates frequently. Sometimes due to the shortage of raw materials, prices soar; sometimes due to fierce competition, prices fall.
To know its accurate market price, do not consult chemical product trading platforms, professional distributors or related production enterprises. They can tell you the exact price according to the current market facts. And you need to pay attention often to grasp the trend of its price.

2-Aminopyridine-4-carboxylic acid is a chemical substance that requires careful attention in many aspects when storing and transporting.
First, when storing, the substance must be stored in a cool, dry and well-ventilated place. This is because the humid environment is prone to moisture absorption and deterioration, affecting quality, while high temperature or poor ventilation may cause chemical reactions and even endanger safety. For example, if placed in a humid corner, moisture will interact with its active groups and change the chemical structure.
Second, keep away from fire and heat sources. 2-Aminopyridine-4-carboxylic acid is flammable, and it is easy to burn in case of open flames and hot topics. Once it catches fire, it is difficult to put it out, and it may release harmful fumes, endangering the environment and personal safety.
Third, when storing, it should be stored separately from oxidants, acids, bases, etc., and must not be mixed. Because of its active chemical properties, contact with these substances may cause severe chemical reactions, such as oxidation-reduction reactions, acid-base neutralization reactions, etc., or cause explosions, toxic gases and other serious consequences.
Fourth, during transportation, it is necessary to ensure that the packaging is complete and sealed. Prevent package damage during bumps and collisions, resulting in material leakage. Once a leak occurs, it will not only cause material loss, but also may cause pollution to the means of transportation and the surrounding environment. If the leak comes into contact with the human body, it will also damage health.
Fifth, the transport vehicle should be equipped with the corresponding variety and quantity of fire fighting equipment and leakage emergency treatment equipment. So that in the event of a sudden fire or leakage accident, it can quickly respond to reduce losses and hazards.
Sixth, the transport personnel must undergo special training and strictly abide by the operating procedures. Familiar with the characteristics of the substance, it can be properly handled in case of emergencies to ensure transportation safety.
