Melting point is of great significance in the identification and identification of substances.
In terms of solubility, 4-hydroxy-3-aminopyridine behaves differently in different solvents. In some organic solvents, such as alcohol solvents, it can exhibit good solubility, just like fish in water, it can blend with solvent molecules and disperse uniformly. However, in water, its solubility may vary or its solubility is limited, showing a partially dissolved state, which is due to the difference in molecular structure and the force between solvent molecules.
Furthermore, its odor is also characteristic. Although it is not a pungent and unpleasant odor, it also has its own unique smell. Although this smell is difficult to describe accurately, it can be distinguished by those who are familiar with it. It is like a unique "charm" that adds a different "color" to it.
In addition, the density of 4-hydroxy-3-aminopyridine is also an important characterization of its physical properties. Under certain conditions, its density is fixed, and this value reflects the degree of compactness of the internal structure of the substance. It is related to other physical properties and together outlines the overall physical properties of the compound.

4-Hydroxy-3-aminopyridine is in the market, and its price range is difficult to determine. The price of this substance often changes for many reasons.
First, the trend of supply and demand is the main reason. If there are many people who want it, but the supply is small, the price may rise; conversely, if the supply exceeds the demand, the price may fall.
Second, the cost of production is also very high. The price of raw materials, the method of preparation, the cost of energy consumption, etc., are all related to cost. If the price of raw materials is high, or the method of preparation is complex and expensive, the cost will rise, and the price will also rise.
Third, the quality is different, and the price is also different. < Br >
Fourth, the competition in the city is also the key. If there are many operators competing with each other, the price may become reasonable; if there are few operators and they are almost monopolized, the price may be controllable in the hands of a few, resulting in a high price.
Looking at the market situation, the price of 4-hydroxy-3-aminopyridine varies from a few yuan to tens of yuan per gram, and even more, the price varies greatly due to special needs, quality or purchase quantity. To know the exact price, consult the supplier of chemical raw materials and check the current market situation in detail.

4-Hydroxy-3-aminopyridine is an important organic compound, and many matters need to be paid attention to when storing and transporting.
First, storage, because of its certain chemical activity, should be stored in a cool, dry and well-ventilated place. If the cover is placed in a high temperature and humid place, or its properties may change, and even chemical reactions may occur. It must be kept away from fires and heat sources, which are prone to combustion or accelerated deterioration. Storage should be separated from oxidants, acids, etc. to prevent mutual reaction and endanger safety. At the same time, suitable materials need to be prepared to contain leaks to prevent accidental leakage, and it can be properly handled in a timely manner.
As for transportation, ensure that the packaging is complete and sealed. The transportation process must be shockproof and anti-drop. Due to violent vibration and collision or damage to its packaging, material leakage will be caused. Transportation vehicles should be equipped with corresponding fire equipment and leakage emergency treatment equipment for emergencies. It is also not allowed to be mixed with contraindicated substances during transportation. Strictly abide by the relevant regulations on chemical transportation. Drive according to the designated route. Do not stop in densely populated areas or traffic arteries.
In short, the storage and transportation of 4-hydroxy-3-aminopyridine should be handled with caution and strictly follow the specifications to ensure the safety of personnel, the environment is not polluted, and the quality of the compound is not affected.
