3-Amino-2-pyrazinecarboxylic acid

3-Amino-2-pyrazine carboxylic acid, this substance has unique chemical properties. It is in powder state, white or off-white in color, and is quite stable under normal conditions.
In terms of its solubility, it is soluble in water, and it can also be dissolved in polar organic solvents such as methanol and ethanol. This is because the amino and carboxyl groups contained in the molecule are hydrophilic, so they can be connected with water molecules by hydrogen bonds, so they are soluble.
3-amino-2-pyrazine carboxylic acid is acidic, which is due to the fact that the carboxyl group can dissociate hydrogen ions. At the same time, the amino group can accept protons and shows a certain alkalinity, so it is an amphoteric compound. In a specific acid-base environment, it can exist in the form of different ions according to the proton transfer status.
In chemical reactions, carboxyl groups can participate in esterification reactions and form corresponding esters with alcohols under suitable catalytic conditions. Amino groups can participate in nucleophilic substitution reactions and interact with halogenated hydrocarbons and other electrophilic reagents to form new compounds. Due to its nitrogen-heterocyclic structure, it is often a key raw material for the construction of complex nitrogen-containing compounds in the field of organic synthesis. It has important application value in the fields of medicine, pesticides and materials science.

The synthesis method of 3-amino-2-pyrazine carboxylic acid has been explored by many parties throughout the ages. The methods are various, and now it is a common way for Jun Chen to say several things.
First, pyrazine is used as the starting material. First, an appropriate substitution reaction is carried out on pyrazine to introduce a specific functional group. For example, through a halogenation reaction, a specific position of pyrazine is connected to a halogen atom. This halogenation reaction requires precise control of the temperature, time and ratio of the reactants to obtain the desired halogenated pyrazine. Then, an amino-containing reagent reacts with it to replace the halogen atom with an amino group to obtain an amino-containing pyrazine derivative. After carboxylation reaction, under suitable conditions, carboxyl groups are introduced to finally synthesize 3-amino-2-pyrazine carboxylic acid. In this process, each step of the reaction needs to be carefully controlled. Due to the slightly poor conditions of each step of the reaction, the purity and yield of the product may be affected.
Second, you can also start from pyrazine derivatives containing carboxyl groups. Protect the carboxyl group first to prevent it from being affected in subsequent reactions. Then, modify other positions on the pyrazine ring, and introduce an amino group through a series of reactions. After the amino group is successfully introduced, the protective group of the carboxyl group is removed to obtain the target product. This path requires proper selection of protective groups, not only to ensure that it can effectively protect the carboxyl group, but also to ensure that it is easy to remove under suitable conditions without affecting the structure and properties of other parts of the molecule.
Third, use some heterocyclic compounds with specific structures to construct pyrazine rings through cyclization, and ingeniously design during cyclization to introduce the target amino group and carboxyl group at the same time or step by step. This cyclization reaction often requires specific catalysts and reaction environments to guide the reaction in the direction of generating 3-amino-2-pyrazine carboxylic acid. The exploration of reaction conditions is crucial, such as temperature, pH, catalyst dosage, etc., all play a decisive role in the reaction process and product formation.

I look at your question, but I am inquiring about the price range of 3-amino-2-pyrazine carboxylic acid on the market. However, the price of this chemical often changes for many reasons, and it is difficult to determine a fixed number.
First, its purity is the key. If the purity is very high, it is close to the high purity reagent grade, and it can reach a very high purity standard, such as 99% or more, the price will be high. The purification process requires fine craftsmanship and many steps, which consume a lot of manpower, material resources, and financial resources. Therefore, the price may be tens of yuan per gram, or even higher. For some high-purity products for special scientific research purposes, it is not uncommon to see more than 100 yuan per gram.
Second, the purchase volume also affects the price. If it is a small number of laboratory trials, the unit price in grams is quite high. However, if you purchase in bulk, such as kilograms or even tons, due to the scale effect, the supplier's cost will be reduced, and the unit price will drop significantly. When purchasing in bulk, the price per kilogram may be reduced to several hundred yuan.
Third, the market supply and demand situation determines the price. If the demand for this chemical is strong, such as a large demand in the field of pharmaceutical research and development, and the supply is limited, the price will rise. On the contrary, if the supply exceeds the demand, the price will tend to decline.
Fourth, different suppliers have different pricing. Well-known large manufacturers, due to brand, quality control and after-sales improvement, prices may be high; while some emerging or small suppliers, in order to compete for market share, prices may be relatively low.
Therefore, to know the exact price range, when consulting various suppliers in detail and comparing quotations from different channels, a more accurate price range can be obtained.
