2-Benzimidazole carboxylic acid is an organic compound with unique physical properties. It is white to pale yellow crystalline powder at room temperature, and its appearance is fine. This appearance is conducive to its dispersion and participation in many chemical reactions and industrial processes.
When it comes to the melting point, it is about 270-280 ° C. The melting point is quite high, reflecting its strong intermolecular force and relatively stable structure. This property allows the substance to maintain a solid state in a high temperature environment and is not easy to melt. In the process of high temperature treatment, it can ensure its own chemical stability and is not easily deteriorated or decomposed due to temperature changes.
In terms of solubility, it is slightly soluble in water and has limited solubility in common organic solvents such as ethanol and acetone. This solubility makes it difficult to dissolve in large quantities in the aqueous phase and most organic solvent systems. This point needs to be taken into account when it comes to solution preparation and reaction medium selection. However, its solubility will increase in specific basic solutions. Due to the presence of groups in the molecular structure of 2-benzimidazole carboxylic acid that can react with bases, salts are formed after the reaction, which increases the solubility in solution. This property facilitates its application in some specific fields, such as in chemical production under alkaline environment conditions.
In addition, 2-benzimidazole carboxylic acid has certain hygroscopicity. Although the moisture absorption is not strong, it will still absorb moisture in the air after being placed in a high humidity environment for a long time. This requires that during the storage process, pay attention to environmental dryness, avoid agglomeration due to moisture absorption or affect its chemical properties, and ensure product quality and stability.

The synthesis of 2-benzimidazole carboxylic acid is a key research in the field of organic synthesis. In the past, the synthesis of this compound followed the classical chemical path.
One method uses phthalamines and dibasic acids or their derivatives as starting materials. Such as taking phthalamines and oxalic acid, in a suitable reaction environment, often using a specific organic solvent as a medium, such as ethanol or dimethylformamide, adding an appropriate catalyst, such as protonic acid or Lewis acid, heated to a certain temperature, usually between 100-150 ° C, through a reaction process of condensation and cyclization to generate 2-benzimidazole carboxylic acid. In this process, the acid and amine groups are first condensed, followed by intramolecular cyclization to form the core structure of benzimidazole, and the carboxyl group is also ingeniously introduced.
There are also those who use o-nitroaniline as the starting material. First, o-nitroaniline is converted into o-phenylenediamine through reduction reaction. Commonly used reducing agents include iron powder, sodium sulfide, etc. Then the target product is obtained according to the above reaction path of o-phenylenediamine and dibasic acid. Although this path is a little complicated, the source of raw materials o-nitroaniline is quite abundant, and the cost may be advantageous.
Another synthesis method using transition metal catalysis has emerged. Using transition metals such as palladium and copper as catalysts, with the assistance of ligands, the precursor containing benzimidazole structure and the reagent containing carboxyl groups are coupled under mild reaction conditions. This method has the advantages of good selectivity and mild reaction conditions, which can effectively avoid the side reactions caused by harsh conditions such as high temperature and strong acid and alkali in traditional methods, and improve the purity and yield of the product. However, the high cost of transition metal catalysts limits their large-scale application. However, with the improvement of catalytic technology, it may become one of the mainstream synthesis methods in the future.

There is a question today, what is the price range of 2-Benzimidazolecarboxylic acid in the market. This is a chemical substance, but the price of the market often changes due to the quality, quantity, urgency, and abundance of supply.
If its quality is pure and excellent, it will be expensive for fine chemical research or high-end pharmaceuticals. In the past, its price ranged from a few gold per gram to tens of gold. If the amount is huge and the supply is abundant, the price may be flat, and the number of gold per gram is the genus.
If the quality is ordinary, it will be used in ordinary chemical industry, and the price will be inexpensive. Or between a few corners and a few gold per gram. And the market conditions are changeable, sometimes the supply is in short supply, the price may jump; sometimes the supply exceeds the demand, and the price also falls.
is to know the exact price, when asking the merchants of chemical materials, or checking the recent market conditions, the price can be obtained, and it cannot be generalized.

2-Benzimidazole carboxylic acid is an organic compound. If you want to store this substance well, you need to understand its storage.
This substance should be placed in a cool and dry place. Cover a cool place to avoid high temperature causing its properties to change. High temperature often promotes chemical reactions to accelerate, or causes it to decompose and deteriorate. And a dry environment is to prevent moisture from invading. Moisture easily reacts with many compounds, impairing its purity, or even forming other things, which damage its original properties.
Furthermore, the storage place must be protected from open flames and hot topics. 2-Benzimidazole carboxylic acid or flammable, in case of open flame, hot topic, fear of fire risk, endangering the storage place and surroundings.
should also be placed separately from oxidizing agents and other substances. The oxidizing agent has high activity and is easy to chemically react with 2-benzimidazole carboxylic acid, causing it to change and lose its original effect. When storing, it should be stored in a sealed container to prevent it from excessive contact with the outside air and avoid oxidation or moisture absorption. In this way, with suitable storage conditions, 2-benzimidazole carboxylic acid can be guaranteed to maintain its inherent properties for a long time, so that it can be used normally when needed.
