2-amino-4,5-dihydro-1,3-thiazole-4-carboxylic acid

2-Amino-4,5-dihydro-1,3-thiazole-4-carboxylic acid, Chinese name for 2-amino-4,5-dihydro-1,3-thiazole-4-carboxylic acid. This is a chemical compound containing thiazolium, which is composed of a sulfur atom, a nitrogen atom and three carbon atoms. In the 4,5 position, there is an amino group (-NH2O) at the 2 position, and a carboxyl group (-COOH) at the 4 position.
The formula can be as follows: With the thiazole core, the nitrogen atom is 1-3 in sequence. It is connected to the amino group at the 2nd position, the carboxyl group at the 4th and 5th positions, and the atom at each of the 4th and 5th positions. In this way, it is formed into a 2-amino-4,5-di- 1,3-thiazole-4-carboxylic acid. This compound may have specific uses in the fields of synthesis and chemistry, because it contains multi-active functionalities, or can be used for the synthesis of specific compounds or biological activities.

2-Amino-4,5-dihydro-1,3-thiazole-4-carboxylic acid, this is an organic compound. It has a wide range of uses and is mostly used as a key intermediate in drug synthesis in the field of medicine. The development of many antibacterial and antiviral drugs often relies on their participation in the construction of specific chemical structures to achieve desired pharmacological activities. For example, the creation of some new antibiotics has taken advantage of their unique chemical properties to enhance the affinity and inhibitory effect of drugs against pathogens.
In the field of pesticides, it also plays an important role. Pesticide products such as insecticides and fungicides can be chemically modified. By interfering with the specific physiological and biochemical processes of pests or pathogens, the purpose of efficient control is achieved, and due to structural characteristics, the impact on the environment is relatively small, which is in line with the development trend of modern green pesticides.
In the field of materials science, 2-amino-4,5-dihydro-1,3-thiazole-4-carboxylic acid can be used as a functional monomer to participate in the synthesis of polymer materials. After polymerization, the material is endowed with unique properties such as special adsorption and ion exchange properties, and is widely used in the preparation of separation membranes, ion exchange resins and other materials to help improve the performance and application range of materials.

The synthesis method of 2-amino-4,5-dihydro-1,3-thiazole-4-carboxylic acid has been known for a long time, and after generations of research, there are many exquisite methods.
First, it can be prepared by condensation reaction between sulfur-containing compounds and nitrogen-containing compounds. First, take suitable thiols, compounds with amino and carbonyl groups, and interact with them in a specific reaction medium under the action of catalysts. At the beginning of the reaction, it is necessary to precisely adjust the temperature and reaction time to promote the full condensation of the two. If the temperature is too high, it is easy to cause frequent side reactions and the product is impure; if the temperature is too low, the reaction will be slow and the efficiency will be poor. The choice of this reaction medium is also very critical. Commonly used are organic solvents, such as ethanol, acetone, etc., which can effectively dissolve the reactants, promote the collision between molecules, and improve the reaction rate.
Second, the derivative of thiazole ring is used as the starting material and is obtained by conversion of specific functional groups. Choose a suitable thiazole derivative, first modify the functional group at a specific position, and gradually introduce amino and carboxyl groups through substitution reaction, oxidation reaction and other means. In this process, the conditions of each step of the reaction need to be carefully controlled. During the substitution reaction, the selected substitution reagents have different activities and different reaction conditions, so it is necessary to choose carefully according to the specific situation. The oxidation reaction requires attention to the amount of oxidant and reaction time to prevent excessive oxidation and affect the purity and yield of the product.
Third, the method of biosynthesis is used. With the help of microorganisms or enzymes, the target product is synthesized under mild conditions. Find a microbial strain with specific catalytic activity, or extract the corresponding enzyme, and put a suitable substrate into the reaction system. The biosynthetic method has many advantages, such as mild reaction conditions, high selectivity, and environmental friendliness. However, it also faces challenges, such as harsh microbial culture conditions and poor enzyme stability. The microbial culture environment, such as temperature, pH, nutrients, etc., needs to be strictly controlled to ensure the activity of microorganisms and the normal play of enzyme catalytic function.
All methods of synthesis have their own advantages and disadvantages. It is necessary to weigh factors such as cost, yield, and purity according to actual needs, and make a prudent choice.

2-Amino-4,5-dihydro-1,3-thiazole-4-carboxylic acid, this material has many properties. It is a white to off-white crystalline powder with pure and positive color.
When it comes to solubility, it is soluble in water because its molecular structure contains polar groups, which meet with water like fish and water, and can form a uniform dispersion system. However, in common organic solvents, such as ethanol and ether, the solubility is poor, and most organic solvents are non-polar, which is contrary to the polarity of the compound, so it is difficult to dissolve.
Melting point is also an important physical property. Its melting point is in a specific range, this value is the inherent property of the substance, like a human fingerprint, unique and recognizable. When the temperature rises to the melting point, the solid 2-amino-4,5-dihydro-1,3-thiazole-4-carboxylic acid gradually turns into a liquid state, the lattice structure disintegrates, and the molecular activity intensifies.
In terms of stability, under normal temperature and pressure and dry environment, it is relatively stable and can maintain its own structure and properties for a long time. However, if placed in a high temperature, high humidity or strong acid and alkali environment, its structure is easily damaged, chemical reactions occur, or hydrolysis, or interaction with acid and base, resulting in changes in the original properties.
These physical properties are of critical significance in many fields. In drug synthesis, solubility affects its absorption in the body, and stability is related to the durability of the drug effect. In chemical production, the melting point can help control the reaction conditions and ensure product quality. Therefore, by clarifying its physical properties, it can be used well and contribute to the development of various industries.

I look at what you are asking about "2 - amino - 4,5 - dihydro - 1,3 - thiazole - 4 - carboxylic acid", which is the name of the chemical substance. However, it is not easy to know its market price range.
The price of this substance often varies depending on many factors. First, the purity is the key. If the purity is very high, it is almost flawless, the price will be high; if the purity is slightly inferior, the price will also drop. Second, the scale of production also has an impact. When mass production is large-scale, the cost may be reduced, and the price will be more affordable; if it is only a small amount of special production, the price will be high. Third, the relationship between market supply and demand is of paramount importance. If there are many people who want it, if there are few people who want it, the price will increase; on the contrary, if the supply exceeds the demand, the price will be self-contained.
According to past experience, the price of such chemicals ranges from a few yuan to several hundred yuan per gram. However, this is only a rough estimate, and it is difficult to determine accurately. To know the exact price, you need to consult a professional chemical reagent supplier, or check the recent trading conditions on the chemical trading platform to obtain a more accurate price range.
