5-Hydroxy-2,3-dihydroxyacetophenone, also known as norepinephrine, is an important organic compound. Its physical properties are quite unique. Under normal temperature and pressure, it is mostly in the state of white to yellow fine powder, and it is delicate to touch. This substance has certain hygroscopicity. When exposed to air, it is easy to absorb water vapor, causing its morphology to change.
When it comes to solubility, 5-hydroxy-2,3-dihydroxyacetophenone is slightly soluble in water, but relatively better in polar organic solvents such as ethanol and acetone. This solubility property makes it play a key role in many chemical reactions and transportation and metabolism processes in living organisms.
Its melting point is about 145-148 ° C. When heated to this temperature range, the substance will gradually change from solid to liquid. This melting point characteristic can provide an important basis for the identification and purification of the substance.
In addition, the stability of 5-hydroxy-2,3-dihydroxyacetophenone is also worthy of attention. Because its molecular structure contains multiple hydroxyl groups, it is easy to be oxidized, especially in light, high temperature and aerobic environment, the oxidation rate is accelerated, and the color may change from light to dark, which affects its quality and activity. Therefore, when storing, it is necessary to pay attention to sealing, avoiding light and placing in a cool and dry place to maintain its chemical stability.
The above physical properties are of great significance in many fields such as medicine and chemical industry, laying a solid foundation for the research, production and application of this substance.

Today there is 5-% hydroxyl-2,3-dihydroxypyridine, what is the market price? This is a rare thing, and the price varies with the quality and the market.
If its quality is high and pure, it is the best choice for various research and industrial use. In the specialized pharmaceutical research workshop and chemical research institute, because it can contribute to the creation of new products and the research of wonderful methods, the price is high. The price per gram of the material can reach hundreds of gold, or even more than a thousand gold. Because of the difficulty of preparation, it requires exquisite craftsmanship, rare materials, and layers of purity to get a good product, which is worth the price. < Br >
However, if the quality is inferior and there are many impurities, it is only suitable for beginner's study and rough and simple test, and the price should be reduced. Or tens of gold ears per gram. This is because the quality is not high, it is difficult to enter the realm of high demand, and it can only be tasted. Therefore, the price cannot be combined with the excellent product.
And the market sentiment also affects its price. If there are many people who want it, and there are few products, and the supply is in short supply, the price will rise. On the contrary, if there is a stock in the market, there are few people who need it, and the price will fall.
There are also different regions of the market, which also make the price different. Prosperous capital, the research industry is prosperous, and those who seek this are more, and the price is high; remote places need less industry and sparse, and the price is low.
In summary, the market price of 5-% hydroxyl-2,3-dihydroxypyridine is high in quality, low in quality, and varies with the supply and demand of the city and the distance of the place. It is difficult to determine the exact value.

5-% hydrazine-2,3-dihydroxypyridine is a chemical substance. When storing and transporting, the following matters should be paid attention to:
First, when storing, be sure to choose a cool and well-ventilated warehouse. This is because of its relatively active chemical properties, high temperature or humid environment is easy to cause reactions. If the temperature of the warehouse is too high, it may cause the substance to decompose, volatilize, and may even trigger dangerous chemical reactions; if the humidity is high, it may be damp and deteriorate, affecting the quality and stability. It should be kept away from fires and heat sources. Because the substance may be flammable, it is easy to burn or even explode in case of open flames, hot topics, and threatens the safety of personnel and facilities.
Second, it needs to be stored separately from oxidants and acids. Do not mix storage. Because of its contact with oxidizing agents or violent redox reactions, a large amount of energy is released, resulting in combustion or explosion; contact with acid substances may also cause chemical reactions, damage the material structure, and produce harmful or dangerous products.
Third, the storage area should be equipped with suitable materials to contain leaks. If leaks occur, they can be dealt with in a timely and effective manner to prevent their spread and reduce the harm to the environment and personnel. For example, preparing inert adsorption materials such as sand and vermiculite can absorb leaked liquids and prevent them from flowing into sewers, soil, etc., polluting the environment.
Fourth, when transporting, ensure that the container does not leak, collapse, fall, or damage. Because it is a chemical dangerous goods, if the container is damaged and the material leaks, it will not only cause waste and loss, but also may pollute the transportation environment and endanger the safety of transportation personnel. The transportation process should follow the specified route and do not stop in densely populated areas and residential areas. Once a leak or accident occurs in a densely populated area, it will cause serious consequences, affecting the lives, health and property safety of many people.
