Because there are strong interactions such as hydrogen bonds between molecules in addition to van der Waals forces, in order to melt or vaporize them, more energy needs to be supplied to overcome these forces, so the melting point is high.
And its stability is also an important physical property. Under normal conditions, these substances are relatively stable, but when exposed to extreme conditions such as strong acids, strong bases or high temperatures, their structures may change. Because some chemical bonds in the molecular structure can be broken or rearranged under specific conditions, resulting in changes in the properties of substances.

Some of these compounds have chiral centers in their molecular structures, which enable them to rotate the vibration direction of polarized light. This property is of great significance in the fields of medicinal chemistry and biochemistry. The activity and metabolic pathways of different optical isomers in organisms may be significantly different.
In summary, the physical properties of 2-%E6%B0%B0%E5%9F%BA%E5%90%A1%E5%95%B6-4-%E7%BE%A7%E9%85%B8%E7%B1%BB%E7%89%A9%E8%B4%A8 such as solubility, melting point, stability and optical rotation have a key impact on its application and research in many fields, which cannot be ignored.

To prepare 2-aminopyridine-4-carboxylic acid, there are various methods.
First, pyridine is used as the beginning, and it is obtained by multi-step transformation. Shilling pyridine halogenation, introducing a halogen atom at a specific position, such as with a suitable halogenating agent, selecting a mild reaction environment, halogenated pyridine can be obtained. Then, the halogenated pyridine reacts with an amino-containing reagent, and is nucleophilic substituted, amino-placed, to form aminopyridine. After that, by carboxylation, with an appropriate carboxylating reagent, under suitable reaction conditions, the specific position of the aminopyridine is carboxylated, and the final 2-aminopyridine-4-carboxylic acid is obtained. < Br >
Second, the compound containing the pyridine ring is used as the starting material. If there are pyridine derivatives with some target structures, they can be obtained by conversion of functional groups. For example, a pyridine derivative contains functional groups that can be converted into amino and carboxyl groups. First, one functional group is converted into an amino group through reduction, substitution, etc.; then through another series of reactions, the other functional group is converted into a carboxyl group, during which the reaction conditions need to be well controlled to prevent side reactions, and the purpose of preparation can also be achieved.
Third, it can be prepared by cyclization reaction. Take a chain-like compound containing a suitable functional group as the raw material and cyclize it within the molecule to construct a pyridine ring. First, the functional groups in the chain-like compound interact to form a ring, and then an amino and carboxyl group are introduced into the ring. Amino groups can be introduced by means of aminolysis, reductive amination, and carboxylation. In this process, it is crucial to precisely design the structure of the chain-like raw materials and regulate the reaction conditions, which is related to the purity and yield of the product.

In today's market, the price of 2-aminopyridine-4-carboxylic acid is between [X] yuan and [X] yuan per catty. This price varies with time and market.
The price of the market is always determined by the situation of supply and demand and production. If there are many people seeking this product, but there are few producers, the price will increase; conversely, if the supply exceeds the demand, the price may drop. And the cost of its production is also the main reason for the pricing. For example, the price of raw materials, the cost of labor, the consumption of equipment, etc., are all related to the price.
In addition, the quality of such goods in the market is also equally poor. The better, the price may be slightly higher; the second, the price may be slightly lower. Buyers should consider their needs, weigh the quality and price, and make a choice.
Watching the market of this industry, the situation changes, and the price fluctuations are unpredictable. However, with common sense, in the near future, the price may still fluctuate between the above domains, but they should also keep an eye on the changes in market conditions at any time.
