3% 2C5 - dihydroxy - 2% 2C6 - diethoxybenzoyl phthalic anhydride, its physical properties are quite specific. The color of this substance is often white as snow, the appearance is like a fine powder, and the quality is extremely fine.
Looking at its melting point, it is about a specific temperature range. At this point, the substance begins to melt from the solid state to the liquid state. This is the key temperature for its phase transition and is also an important indicator for distinguishing its purity. Its boiling point is higher. At the boiling point, the substance will change from liquid to gas state. This process requires sufficient energy to overcome the force between molecules.
When it comes to solubility, it shows a certain solubility in common organic solvents, such as ethanol and acetone. In ethanol, it can be slowly dissolved, making the solution slightly cloudy and then gradually clear. However, in water, its solubility is very small and almost insoluble. This is due to the ratio of polar and non-polar parts in its molecular structure.
Furthermore, its density is also fixed. It is heavier than water and is placed in water, that is, sinks to the bottom of the water. Its texture is light and feels smooth to the touch. If it is slippery as fine sand, it is more soft. And the stability of this substance is quite good. Under normal temperature and humidity conditions, it can maintain its chemical structure and physical form unchanged for a long time. However, in case of extreme chemical environments such as strong acids and bases, their physical properties may change due to chemical reactions.

To prepare 3% 2C5-dihydroxy-2% 2C6-dimethoxybenzoic anhydride, the method is as follows:
First, the starting material is selected properly, and the compound containing the corresponding functional group can be selected, such as benzene derivatives with suitable substituents such as methyl and hydroxyl groups. This is the synthetic root.
Second, the step of hydroxy protection is performed. Due to the high activity of hydroxyl groups in the reaction, it is easy to produce side reactions, so it is necessary to cover it with suitable protective groups. For example, a silicon ether protective group is used, and the protective group is bonded to the hydroxyl group under suitable solvent and alkali catalysis to achieve the purpose of protection and ensure its stability in subsequent reactions.
Furthermore, a methoxy group is introduced. The nucleophilic substitution reaction can be used to select active halogenated methane, such as iodomethane. In an alkaline environment, the halogen atom of the halogenated methane is replaced by the nucleophilic anion of phenolic hydroxyl oxide to form a methoxy group.
Then, the structure of benzoic anhydride is constructed. The intermediate product with carboxyl group is dehydrated and condensed by the action of dehydrating agent, such as acetic anhydride or phosphorus oxychloride, at a suitable temperature and reaction time to obtain the structure of benzoic anhydride.
In the meantime, each step of the reaction requires precise temperature control, time control, and proportion control of the reactants. The reaction process and product purity are monitored by means of thin layer chromatography and nuclear magnetic resonance. After each step is completed, the hydroxyl protecting group is removed. According to the type of protecting group, the appropriate conditions are selected to remove it to obtain the target product 3% 2C5-dihydroxy-2% 2C6-dimethoxybenzoic anhydride. In this way, the purpose of synthesis can be achieved after careful operation in multiple steps.

3% 2C5-dihydroxy-2% 2C6-dimethoxybenzoic anhydride, when storing and transporting, pay attention to many matters.
Its properties may be more active and sensitive to temperature. At high temperature, it may cause decomposition and deterioration. Therefore, the storage place should be a cool and dry place, and the temperature should be maintained in a suitable range, not too high, in order to prevent its chemical structure from being damaged, thereby damaging the quality.
Furthermore, this substance may have a certain degree of hygroscopicity. If the ambient humidity is high, it is easy to absorb water vapor, causing its properties to change, or affecting subsequent use. In the place where it is stored, the humidity also needs to be strictly controlled, and the environment can be maintained dry with the help of desiccants and other substances.
During transportation, turbulence and vibration should also be taken seriously. Violent vibration or damage to the container, causing material leakage. The packaging must be solid and stable to ensure safe transportation. And it should be avoided to mix with other chemicals to prevent chemical reactions and generate danger.
At the same time, because of its certain chemical activity, it is exposed to the air for too long, or reacts with oxygen, carbon dioxide and other ingredients in the air. When the storage container is well sealed, it is also necessary to ensure that the packaging is tight during transportation to minimize contact with the air.
During handling, operators must be careful and follow specific operating procedures. In case of accidental contact with skin or eyes, correct handling measures should be taken immediately to ensure personal safety. In this way, 3% 2C5-dihydroxy-2% 2C6-dimethoxybenzoic anhydride must be properly stored and transported to ensure its quality and safety.

I think what you are asking is about the market price range of 3,5-dihydroxy-2,6-dimethoxypyridine dicarboxylate. However, the price of this product often varies due to many factors, and it is difficult to determine drastically.
The change in its price is mainly due to the situation of supply and demand. If there are many people in the market who need it, but there are few people who produce it, the price will increase; conversely, if the supply exceeds the demand, the price may drop. Furthermore, the price of raw materials is also a major factor. The fluctuation of the price of the raw materials required to make this product will cause the price of the finished product to fluctuate. If the raw materials are rare and expensive, the price of the finished product will also be high; if the raw materials are abundant and cheap, the price of the finished product may decrease.
In addition, the simplicity of the production process and the quality of the quality also affect the price. Those with complex processes and high quality will be expensive; those with simple processes and slightly inferior quality will be slightly lower.
If you want to know the market price range, you should carefully observe the chemical market conditions, visit the industry merchants, manufacturers, or refer to professional market survey reports. Generally speaking, the price of such chemicals may fluctuate within a certain range due to specific specifications, purity, number of transactions and market conditions, but it is difficult to determine. Those who need to personally explore the market can obtain an accurate price range.
