Aminopyrazine, 2-

Fu2-aminopyrazine is a nitrogen-containing heterocyclic compound. It is basic, because the nitrogen atom exists in the pyrazine ring, has lone pairs of electrons, and can accept protons, so it is alkaline.
Its chemical activity is also quite high. Amino is a nucleophilic group and can participate in many nucleophilic substitution reactions. Under suitable conditions, it can react with halogenated hydrocarbons. The nitrogen atom of the amino group attacks the carbon atom of the halogenated hydrocarbon, and the halogen atom leaves to form a new carbon-nitrogen bond.
And because of its conjugate system, the electron cloud distribution is relatively special, resulting in a certain stability. However, when encountering strong oxidants, the conjugated system may be destroyed, triggering an oxidation reaction.
In the field of organic synthesis, 2-aminopyrazine has a wide range of uses. It can be used as a key intermediate for the synthesis of drugs, pesticides and dyes. By chemically modifying its amino and pyrazine rings, compounds with diverse structures and functions can be constructed.
In terms of physical properties, it is mostly solid at room temperature, with a certain melting point and boiling point. And because of the interaction of hydrogen bonds and van der Waals forces between molecules, its solubility is affected. In polar solvents, because hydrogen bonds can be formed with solvent molecules, the solubility is good; in non-polar solvents, the solubility is poor. In conclusion, 2-aminopyrazine has unique chemical properties and is widely used in many fields of organic chemistry.

2-Aminopyrazine has a wide range of uses. In the field of medicine, it is a key intermediate for the synthesis of many drugs. Gein pyrazine compounds have unique chemical structures and biological activities. After ingenious chemical modification, antibacterial, antiviral, anti-tumor and other drugs can be prepared. For example, when developing new antibacterial drugs, the structural characteristics of 2-aminopyrazine may help the drug to accurately act on the target of pathogens and inhibit the growth and reproduction of pathogens.
In the field of materials science, 2-aminopyrazine also has outstanding performance. It can participate in the synthesis of polymer materials with specific functions. Due to its nitrogen-containing heterocyclic structure, the material can endow unique electrical, optical and thermal properties. For example, in the preparation of organic optoelectronic materials, the introduction of 2-aminopyrazine structure can improve the charge transport ability of the material and improve its photoelectric conversion efficiency, which can be used to fabricate better Light Emitting Diodes, solar cells and other devices.
In chemical production, 2-aminopyrazine can be used as a catalyst or catalyst auxiliary. Its unique electron cloud distribution and reactivity can effectively promote the progress of certain chemical reactions, improve the reaction rate and yield. For example, in specific organic synthesis reactions, adding an appropriate amount of 2-aminopyrazine can make the reaction conditions milder, reduce energy consumption and side reactions, and improve the economic efficiency and environmental friendliness of chemical production.
In addition, in the field of pesticides, 2-aminopyrazine can be rationally derived, or high-efficiency, low-toxicity and environmentally friendly pesticide products can be prepared, which can help agricultural pest control and ensure crop harvest. All these show that 2-aminopyrazine has important value and broad application prospects in many fields.

There are various paths for the synthesis of Fu 2-aminopyrazine, which are described in detail today.
First, pyrazine is used as the group to carry out the reaction of amination. Under specific conditions, such as high temperature and the existence of a suitable catalyst, the nitrogen atom in ammonia can replace the hydrogen atom on the pyrazine ring to form 2-aminopyrazine. This catalyst may be a metal oxide or the like, which can reduce the activation energy of the reaction and promote the progress of the reaction. The control of temperature is extremely important. If it is too high, side reactions will occur, and if it is too low, the reaction rate will be slow. An appropriate temperature range should be found to make the reaction efficient and the yield good.
Second, it is formed by the cyclization reaction of nitrogen-containing compounds and carbon-containing compounds. For example, specific nitrogen-containing diamines and compounds containing dicarbonyl groups can undergo intramolecular cyclization and condensation under the action of appropriate solvents and catalysts. In this process, the chemical bonds in the molecule are rearranged and condensed, and the pyrazine ring is gradually constructed, and an amino group is introduced at a specific position. The nature of the solvent has a great influence on the reaction. The choice of polar solvent or non-polar solvent is related to the solubility of the reactants and the stability of the reaction intermediates.
Third, the halogenated pyrazine is used as the starting material to make it nucleophilic substitution reaction with ammonia or amine compounds. Halogen atoms are highly active. Ammonia or amine nitrogen atoms are rich in electrons and nucleophilic. They can attack the carbon atoms connected to the halogen atoms of halopyrazine, and the halogen atoms leave to obtain 2-aminopyrazine. During the reaction, the solvent, temperature and the ratio of the reactants need to be carefully regulated. The solvent must be able to dissolve the reactants and not overreact with the reactants. Temperature affects the reaction rate and selectivity, and the ratio of the reactants depends on the completeness of the reaction and the purity of the product.
These methods have their own advantages and disadvantages. In practical application, according to the availability of raw materials, cost considerations, product purity requirements and other factors, the appropriate method is selected to achieve the purpose of efficient synthesis of 2-aminopyrazine.

I haven't heard of the price range of "2-aminopyrazine" in the market. However, if you want to know its price, you can follow several ways. First, visit various pharmaceutical restaurants and chemical stores. There are often all kinds of chemical reagents, or you can inquire about the price of this product. If it is a common chemical raw material, it may be prepared in the store, and the clerk can tell the price. Second, look at the chemical raw material trading website. In today's world, the Internet is convenient, and many chemical products are available on such platforms. Go to it and search for "2-aminopyrazine", and you can get quotes from different merchants. Merchants vary in price depending on supply, quality and quantity. Third, inquire about chemical manufacturers. The manufacturer is the source of the product. If you can contact it, ask for the wholesale price, or get the actual price. However, the manufacturer may not sell it because of the small quantity, and mostly trade in batches. In short, if you want to determine the price of "2-aminopyrazine", you should explore more ways and compare the quotations to obtain a more accurate price range.
