1H-Imidazole-5-carboxylic acid

1H-imidazole-5-carboxylic acid, which is one of the organic compounds. Its chemical structure is quite unique, composed of an imidazole ring and a carboxyl group.
Looking at its imidazole ring, this is a five-membered heterocyclic ring containing two nitrogen atoms, which is aromatic. Two of the nitrogen atoms are located in a special position in the ring, giving the ring a unique electron cloud distribution and chemical activity. In 1H-imidazole-5-carboxylic acids, "1H" indicates that the hydrogen atom is attached to the nitrogen atom at a specific position in the imidazole ring. This specific connection method has a profound impact on the overall properties of the compound.
Furthermore, the carboxyl group (-COOH) is attached to the 5 position of the imidazole ring. The carboxyl group is a strongly polar group and is acidic. Due to its existence, 1H-imidazole-5-carboxylic acids can exhibit typical properties of carboxylic acid compounds, such as neutralization with bases to form corresponding salts.
From the perspective of electronic effects, there is an interaction between the imidazole ring and the carboxyl group. The electron cloud of the imidazole ring can produce a conjugation effect with the carboxyl group, which affects the acidity of the carboxyl group; conversely, the electron-absorbing effect of the carboxyl group also affects the electron cloud density distribution on the imidazole ring, thereby changing the reactivity of each position on the ring.
Overall, the chemical structure of 1H-imidazole-5-carboxylic acid, due to the ingenious combination of imidazole ring and carboxyl group, makes the compound show potential application value in many fields such as organic synthesis and medicinal chemistry. It is an organic compound worthy of further investigation.

1H-imidazole-5-carboxylic acid, this is an organic compound. Its main physical properties are as follows:
Under normal temperature and pressure, it is mostly white to light yellow crystalline powder, with fine texture and visible powder state. This form is easy to store and use, and it is also convenient for many chemical operations.
As for the melting point, it is about 290 ° C - 300 ° C. The melting point is quite high, indicating that the compound has strong intermolecular forces and relatively stable structure. Such a high melting point makes it able to maintain a solid state at general ambient temperature, and it is not easy to change its state due to temperature fluctuations.
In terms of solubility, 1H-imidazole-5-carboxylic acid is slightly soluble in water. This property is related to the ratio of polar groups and non-polar parts in the molecular structure. Although it can be dissolved to a certain extent in water, the solubility is limited. The dissolution process requires appropriate conditions, such as stirring, heating and other auxiliary means, to promote more solute dispersion in the solvent. In organic solvents, its solubility is also different. It has a certain solubility in some polar organic solvents such as methanol and ethanol, but it is difficult to dissolve in non-polar organic solvents such as n-hexane and benzene. This difference in solubility provides a basis for its separation, purification and application in different reaction systems.
In addition, 1H-imidazole-5-carboxylic acid has certain hygroscopicity. Because its molecular structure contains groups that can form hydrogen bonds with water molecules, it is easy to absorb water vapor in the air in a humid environment, resulting in an increase in its own water content. Pay attention to the ambient humidity during storage to prevent it from affecting the quality and performance due to moisture absorption.
The physical properties of this compound are widely used in organic synthesis, pharmaceutical chemistry and other fields, laying the foundation for related research and production.

The synthesis method of 1H-imidazole-5-carboxylic acid has been known for a long time. In the past, many scholars studied the field of organic synthesis and obtained many methods.
One is to start with a suitable nitrogen-containing heterocyclic precursor. Imidazole compounds with specific substituents can be found, and carboxyl functional groups can be introduced through carefully designed reaction pathways. For example, choose an imidazole derivative, in a suitable reaction medium, with the catalytic assistance of a base, interact with carboxylating reagents such as carbon dioxide. This process requires detailed control of reaction temperature, pressure and time. If the temperature is too low, the reaction will be slow and the carboxylation efficiency will not be obvious; if the temperature is too high, side reactions will easily occur, resulting in impure products. < Br >
Second, to construct an imidazole ring as a base. Simple compounds containing nitrogen and carbon, such as nitriles, amines and carbonyl compounds, can be used to construct an imidazole ring through multi-step reaction, and then carboxyl groups are introduced. First, the nitrile and amine are condensed under specific conditions to obtain intermediate products, and then the target molecule is gradually formed through cyclization, oxidation and other steps. Although the steps are complicated, each step has its own subtlety. The fine-tuning of each reaction condition, such as the pinch of pH and the selection of catalysts, is related to the yield and purity of the product.
Third, learn from the concept of biosynthesis. With the help of the catalytic properties of enzymes, the synthesis of 1H-imidazole-5-carboxylic acid can be achieved under mild conditions. Using a specific enzyme as a catalyst, in an aqueous solution or buffer system, with a specific substrate as raw material, the target product is efficiently generated by using the high specificity of the enzyme. The beauty of biosynthesis is that it is green and environmentally friendly. The reaction conditions are mild, but it requires strict activity and stability of the enzyme, and the preparation of the enzyme is not easy.
All kinds of synthesis methods have their own advantages. Either heavy efficiency, or purity, or green environmental protection. The way of synthesis is like exploring a hidden path. It requires careful study by organic synthesizers and weighing the pros and cons to obtain an ideal synthesis scheme for the preparation of 1H-imidazole-5-carboxylic acid.

1H-imidazole-5-carboxylic acid, this product is in the market, and its price is difficult to determine. The price of the cap often varies for various reasons. First, it is related to quality. If the quality is high and pure, and the high standard is required, the price will be high; on the contrary, if the quality is poor, the price should be low. Second, the quantity is also required. If you buy a large quantity, you will often get a discount, and the unit price will drop; if the quantity is small, the price may not be excellent. Third, the supply and demand of the city also affect its price. If you need more supply and less supply, the price will rise; if the supply exceeds the demand, the price will fall. Fourth, the source of production is related to transportation. If you lose a long way, the fee will increase, and the price will rise; if you are close to the source and convenient, the price will be stable.
Looking at the markets, the price is not detailed. Or there are grams, or the price of the batch. Generally speaking, the quality of the sample is still good, or a few yuan to a few tens of yuan per gram; if you buy in large batches, per kilogram or a few hundred yuan to a few thousand yuan. However, these are all approximate numbers. The actual price must be confirmed by consulting the pharmaceutical raw material supplier, reagent supplier, etc. Buyers should carefully observe the situation and weigh the quality price in order to obtain good results.
