2-Amino-5-hydroxypyridine is one of the organic compounds. In terms of the stability of its chemical properties, many factors need to be explored in detail.
In terms of molecular structure, its pyridine ring has a certain stability. Because the pyridine ring is a conjugated system, the electron cloud distribution is relatively uniform, giving the molecule a certain stability. The introduction of amino and hydroxyl groups has an impact on the stability. The nitrogen atom of the amino group has lone pairs of electrons, which can participate in the conjugation system, which can increase the electron cloud density and enhance the stability to a certain extent.

In a chemical environment, the stability of 2-amino-5-hydroxypyridine is influenced by factors such as temperature and pH. When the temperature rises, the molecular thermal motion intensifies, and the chemical bond vibration enhances, resulting in a decrease in stability. In an acidic environment, amino groups are easily protonated, changing the molecular charge distribution and electron cloud structure, or changing the stability; in an alkaline environment, hydroxyl groups may participate in the reaction and affect the stability.
In terms of chemical reaction activity, both amino and hydroxyl groups are active check points and can participate in many reactions, such as nucleophilic substitution, acylation, alkylation, etc. Such reactions may change the molecular structure and affect the stability.
Overall, the stability of 2-amino-5-hydroxypyridine is not absolute, but varies according to the specific environment and conditions.

The synthesis method of 2-amino-5-hydroxypyridine has been known for a long time. The methods are diverse, each has its own advantages and disadvantages, and has also evolved over time.
First, it can be initiated by specific pyridine derivatives. After delicate reactions, such as substitution reactions with specific reagents under suitable conditions, the pyridine matrix is first placed in a carefully prepared reaction system, which contains suitable solvents, catalysts, etc. The catalyst is the key to the reaction, which can significantly change the rate of chemical reactions and make the reaction proceed in the desired direction. Under the right temperature and pressure, the reagent is fully contacted with the pyridine parent body, and after a series of complex chemical changes, the structure of the target molecule is gradually constructed, and the final product is 2-amino-5-hydroxypyridine.
Second, it can also use small molecules containing nitrogen and oxygen as raw materials. Through multi-step reactions, atoms are cleverly spliced to form a pyridine ring. Initially, the small molecule raw materials undergo a condensation reaction in a specific reaction step to form the skeleton structure of the foundation. Subsequently, amino and hydroxyl groups are precisely introduced through modification steps. This process requires strict control of the reaction conditions. Slight deviations in temperature and pH may affect the purity and yield of the product. Each step of the reaction requires fine operation, just like carving beautiful jade, so that the atoms can be arranged as expected to achieve the target product.
Furthermore, there is the use of biosynthesis. With the help of enzymes in the body, with their efficient and specific catalytic ability, the reaction is promoted. In a suitable biological system, providing a suitable substrate, the enzyme can play its unique role in guiding the substrate to react and generate 2-amino-5-hydroxypyridine. This biosynthesis method is relatively green and environmentally friendly, and the reaction conditions are mild. However, it requires a high degree of biological system.

The price of 2-amino-5-hydroxypyridine in the market varies for various reasons. This compound has a wide range of uses and is useful in many fields such as medicine, pesticides, materials, etc. The demand for it has a deep impact on the price.
If the quantity is high, the supplier may reduce its price due to the scale effect; on the contrary, if the quantity is low, the price may increase. Furthermore, the difficulty of its production also affects the price. The synthesis of this compound requires specific reaction steps. The price of the raw material and the control of the reaction conditions are all related to the cost. If the raw material is scarce and the price is high, or the reaction conditions are harsh, the cost will increase, and the price will also rise.
Looking at past market conditions, its price fluctuates within a certain range. However, due to rapidly changing market conditions, it is difficult to determine its exact price range. According to past transactions and market speculation, its price may vary due to quality and supply volume, and the price per gram may range from tens of yuan to hundreds of yuan. For real-time and accurate prices, it is advisable to consult chemical product suppliers, chemical raw material trading platforms, etc., where the exact quotation can be obtained at the moment to meet the needs of procurement or research.
