1 . **酸碱性**
This substance is acidic, because the molecule contains a carboxyl group (\ (-COOH\)), the carboxyl group can ionize hydrogen ions (\ (H ^{+}\)）， in water to exhibit acidity. It can neutralize with bases, such as with sodium hydroxide (\ (NaOH\)), and the hydrogen ion in the carboxyl group combines with the hydroxide ion (\ (OH ^{-}\)）) to form water, resulting in the corresponding carboxylate and water.
2 . **氧化能力**
Some atomic valence states in this compound can be changed and have certain redox properties. Some of the atoms are in an elevated valence state. When encountering strong oxidants, electrons can be lost and oxidized, and their own valence state increases. For example, when encountering strong oxidants such as potassium permanganate (\ (KMnO_ {4}\)), the molecular structure may change, and some atomic valence states increase.
3 . **酯化�应**
Because of its carboxyl group, it can be esterified with alcohols under the condition of concentrated sulfuric acid as a catalyst and heating. Taking ethanol (\ (C_ {2} H_ {5} OH\)) as an example, the hydroxyl group in the carboxyl group (\ (-OH\)) combines with the hydroxyl hydrogen in the ethanol to form water, and the remaining part is connected to form an ester compound and water. This is a reversible reaction, and the control of the reaction conditions can promote the balance to move in the direction of ester formation.

If it is in an alkaline environment, 2-pentyl-5-methylfuransuccinic acid will undergo hydrolysis. Under alkaline conditions, the carboxyl group reacts with the base, and at the same time some chemical bonds in the molecule are broken, which reacts with water to change the molecular structure and generate corresponding hydrolysis products.

2-% Ming-5-methylaminobutyric acid is synthesized as follows:
First, indole is used as the starting material. First, indole formaldehyde and dimethylaminoic acid are reacted to the appropriate components. This step aims to introduce aminomethyl to generate N- (dimethylaminomethyl) indole. This reversal needs to be controlled in terms of the degree, the proportion of the reversal, and the proportion of each reactant, and whether it is easy to produce side reactions. In addition, N - (dimethylaminomethyl) indole is oxidized by appropriate oxidation methods, such as dioxides or high acid, etc., to obtain indole formaldehyde. In this oxidation step, special attention should be paid to the amount of oxidizer and the acidity of the reaction environment, so as to ensure the direction of generating indole formaldehyde. The most important, so that indole formaldehyde diethyl malonate under the action of alcohol and other catalysis Knoevenagel reaction, and then the hydrolysis, carboxylic and other steps, can be obtained 2-% Ming-5-methylindole butyric acid.
Second, to nitrotoluene starting material. First a series of anti, such as nitrification, original, etc., to prepare aminobenzoic acid. Aminobenzoic acid diazotization reaction, to generate diazo, then acrylonitrile addition reaction, to generate a phase of nitrile compound. This nitrile compound hydrolysis, esterification and other reaction, can be obtained from the ester of the phase This, the ester methyl Grignard reaction, the introduction of methyl, and then a series of functionalities, the most synthesis of 2-% Ming-5-methylindole butyric acid. There are many steps in this way, but each step is combined with the other, which is convenient for operation and control.
Third, the starting material is 2-methylindole. The 2-methylindole succinic anhydride is made in the presence of catalysis such as water trichloride, and the Friedel-Crafts acetylation reaction is produced in a suitable solution to generate a phase acetylation reaction. This reaction needs to be carried out in the environment of water, because of the catalytic activity of water. In this way, the acetylation reaction can also successfully synthesize 2-%-5-methylindole butyric acid through a series of reactions such as protogenesis and hydrolysis. The starting material phase of this method is easy to obtain, and the reaction is direct, which has a certain application prospect in industrial production.

I have heard your inquiry about the market price of 2-hydroxy- 5-methylfuranoic acid. This chemical is widely used in the chemical industry, and its price often varies due to many factors.
First, the trend of supply and demand is the main reason. If there is a strong demand for it in industrial preparation, scientific research experiments, etc., and the supply is relatively scarce, the price will tend to rise; conversely, if the supply exceeds the demand, the price will decline.
Second, the quality specification also affects the price. Products with high purity, few impurities, and meet specific industry standards are more expensive than those with general quality. High-purity 2-hydroxy- 5-methylfuranic acid is often used in high-end pharmaceutical research and development and other fields. It has strict quality requirements, and its price is naturally high.
Furthermore, the cost of raw materials is also related to its price. If the price of raw materials for preparing this chemical fluctuates, the production cost of 2-hydroxy- 5-methylfuranic acid will be different, which will affect the market price. If raw materials are scarce or the difficulty of collection and production increases, the cost will rise, and the price of its products will also rise.
Regional differences cannot be ignored. Different places have different prices due to differences in transportation costs and market competition. In prosperous cities or places where the chemical industry gathers, the price may be relatively stable due to convenient logistics and sufficient competition; while in remote areas, due to inconvenient transportation and limited market size, the price may be slightly higher.
According to the current market, the price per kilogram may be between hundreds and thousands of yuan. However, this is only an approximation. The real-time price can only be obtained by consulting chemical raw material suppliers, chemical trading platforms, or industry veterans in detail.

2-% Jiang-5-methyluracil should be placed in a cool, dry, well-ventilated place, away from fires and heat sources. Due to its more active nature, it is easy to decompose and deteriorate when heated, so the storage temperature should be controlled between 15 and 25 degrees Celsius, and the humidity should be maintained at 40% to 60%.
This substance is quite sensitive to light, and light will trigger a series of complex photochemical reactions, resulting in structural changes and reduced activity. Therefore, it needs to be stored in a brown bottle to block the influence of light on it, and should be placed in a dark place.
In addition, 2-% Jiang-5-methyluracil acid has certain chemical activity and is easy to react with certain chemicals. Therefore, it should not be stored with strong oxidizing agents, strong acids, strong bases and other substances to avoid dangerous chemical reactions, resulting in material loss and safety hazards.
