1H-imidazole-4-carboxylic acid, this material property is special and related to chemistry. It is a white to off-white solid, which is quite stable at room temperature and pressure. Looking at its boiling state, the melting point is quite high, about 280-284 ° C. Due to the intermolecular force, it requires a higher temperature to break its lattice and turn the solid state into a liquid state. As for the boiling point, it is difficult to determine precisely because it is easy to decompose at high temperature.
Solubility is also an important physical property. In water, 1H-imidazole-4-carboxylic acid has a certain solubility, which is due to the fact that there are groups in the molecule that can form hydrogen bonds with water molecules, such as the nitrogen atom of the carboxyl group and imidazole ring, which can make a blind date with water, but the solubility is not very high, because the hydrophobic part of the molecule is also affected. In common organic solvents, such as ethanol and acetone, the solubility is slightly inferior to that of water, only slightly soluble or insoluble, which is determined by the degree of force matching between the solvent and the solute.
Then again, its acidity and alkalinity, because it contains carboxyl groups, it is acidic, and can weakly ionize hydrogen ions in water. It exhibits the characteristics of acid in solution and can neutralize with bases to generate corresponding salts and water. And the nitrogen atom of the imidazole ring is alkaline and can accept protons. This amphoteric characteristic enables 1H-imidazole-4-carboxylic acid to exhibit unique chemical behavior under specific conditions.
In addition, 1H-imidazole-4-carboxylic acid has certain hygroscopicity. When placed in a high humidity environment, it is easy to absorb moisture from the air, resulting in a gradual change in its shape or properties. When storing and using, this characteristic should be paid attention to in detail and should be properly sealed to prevent moisture decomposition and ensure its quality and performance stability.

The synthesis method of 1H-imidazole-4-carboxylic acid has been known for a long time, and it has become more and more diverse with the passage of time.
First, this goal can be achieved by taking a suitable nitrogen-containing heterocyclic compound as the starting material and going through a multi-step reaction. First, a specific nitrogen heterocyclic ring is taken, and under suitable reaction conditions, a nucleophilic substitution is performed with a certain reagent to modify the specific position. This step requires precise control of temperature, reaction time and reagent dosage. Due to high temperature or long time, side reactions are easy to occur, which affects the purity and yield of the product. After the modification, the specific group is converted into a carboxyl group through an oxidation step with the help of a specific oxidizing agent, thereby constructing the structure of 1H-imidazole-4-carboxylic acid.
Second, there is also a method of starting with amino acids. With a specific amino acid as the base, the amino and carboxyl groups are properly protected to prevent unnecessary side reactions in subsequent reactions. Then, through a cyclization reaction, an imidazole ring structure is formed. This cyclization reaction condition is very critical, and a specific catalyst and reaction environment are required to generate the desired imidazole ring efficiently and with high selectivity. Finally, the protective group is removed to obtain 1H-imidazole-4-carboxylic acid.
Furthermore, there is still a synthesis path catalyzed by transition metals. Select a suitable substrate and construct the structure of the target product through a series of reactions such as coupling and cyclization in the presence of transition metal catalysts. The activity and selectivity of transition metal catalysts have a great impact on the reaction process and product yield. It is necessary to carefully screen the catalysts and optimize the reaction conditions, such as the choice of solvent, the type and dosage of bases, etc., to ensure the smooth progress of the reaction and the efficient synthesis of 1H-imidazole-4-carboxylic acid. These methods have their own advantages and disadvantages, and the practical application needs to be carefully selected according to specific needs and conditions.

The price of 1H-imidazole-4-carboxylic acid in the market is difficult to determine. This price varies with various factors, such as the supply and demand of the market, the cost of production, the quality of quality, and time and place are also affected.
Looking at the past, the market for chemical raw materials is changeable. When the demand for prosperity and supply is low, the price often rises; if the supply exceeds the demand, the price may fall. The production and demand of 1H-imidazole-4-carboxylic acid is also affected by the situation of medicine, agrochemical industry. The research and development of medicine, the demand or increase for it, the price will rise; if the market of agrochemicals is weak, the price will be reduced and the price will fall.
The main reason is the production of this. The procurement of raw materials, the process of construction, and energy consumption are all related to this. The source of raw materials is thin, and the procurement cost is high, resulting in an increase in production costs and high prices. If the work is complicated, the consumption is large and the efficiency is low, and the price also rises.
The quality is different, and the price is also different. Those with high purity and high quality are needed in high-end use, and the price is high; those with ordinary quality, the price is low.
There are also differences between time and place. In peak season, the price is high; in off-season, it is the opposite. Different places vary due to taxes, transportation, etc., and the price is different. In remote places, the cost of transportation is high, and the price may increase.
In summary, the market price of 1H-imidazole-4-carboxylic acid ranges from tens of yuan per kilogram to hundreds of yuan. To know the exact price, it depends on the real-time market conditions and suppliers.

For 1H-imidazole-4-carboxylic acids, many matters must be paid attention to during storage and transportation.
Its properties may be unstable, so when storing, the temperature and humidity of the environment should be the first priority. It should be stored in a cool, dry place, away from heat and fire sources. If the temperature and humidity are inappropriate, or it may deteriorate, affecting the quality. Under high temperature, this compound may decompose and cause damage to its components; if the humidity is too high, it is prone to deliquescence, which reduces its purity.
Furthermore, this product may be sensitive to light. Under light, or photochemical reactions, the structure may change. It is best to choose a dark place for storage, and use a shading container, such as a brown bottle, to ensure its stability.
During transportation, protection measures are also crucial. It is necessary to ensure that the packaging is intact to prevent leakage. Because it may have a certain chemical activity, after leakage, or react with surrounding substances, it will not only endanger the safety of transportation but also damage the quality of the product. When handling, it should also be handled with care to avoid shock and pressure, and prevent package damage.
At the same time, this compound may have certain chemical hazards. When transporting, it must be operated in accordance with relevant regulations and standards. Transportation personnel should be aware of its characteristics and emergency response methods. In case of emergencies, they can respond in time to avoid major disasters.
