The method of synthesis of 5-amino-5-cyanopyrazine is one of the most important tasks in chemical research. To make this substance, one of the common methods is to use pyrazine derivatives as the starting material. First take a suitable pyrazine precursor, in a suitable reaction environment, with specific reagents and conditions, so that it can be gradually converted.
The first step, or choose a pyrazine compound, its structure should have a modifiable check point, that is, the amino group and cyano group are introduced into the base. Placing this pyrazine substrate in the reactor, adding an appropriate amount of base, base, can adjust the pH of the reaction system, so that the reaction is smooth. In this environment, reagents that can provide amino groups, such as ammonia derivatives, are added. Through nucleophilic substitution and other reaction mechanisms, the amino groups are gradually connected to specific positions on the pyrazine ring. This process requires fine temperature control. If the temperature is too high or too low, the reaction rate can be abnormal or by-products can be formed.
After the amino group is connected, the next step is the introduction of the cyano group. At this time, it can provide sources of cyanide, such as potassium cyanide, sodium cyanide, etc. (when using this type of cyanide, pay attention to its toxicity and strictly abide by the operating specifications). Under another specific reaction condition, or accompanied by a catalyst, the cyano group is promoted to react with the amino-containing pyrazine intermediate to obtain 5-amino-5-cyanopyrazine.
There are other methods, or starting from more basic raw materials, through multi-step reactions, the pyrazine ring is constructed, and the amino group and cyano are introduced in an orderly manner. For example, small molecules containing nitrogen and carbon are gradually constructed by a series of reactions such as condensation and cyclization. However, this path is often complicated and requires precise control of each step of the reaction. The purity and yield of the product can be affected from the proportion of raw materials, reaction time, and even the material and stirring rate of the reaction equipment.
The method of preparing 5-amino-5-cyanopyrazine, although not the same, requires following chemical principles and operating procedures to be expected to obtain pure and sufficient products.

5-Amino-5-cyanopyrazine is in the market, and its price is difficult to determine. The market situation of this compound often changes due to a variety of reasons. Its preparation is difficult and easy, and it depends on the price. If the preparation method is difficult, requires multiple processes, special reagents, and the yield is not high, its price is high or high. On the contrary, if the preparation is easier, the price or slightly cheaper.
Furthermore, the state of market supply and demand also affects its price. If there are many applicants, but there are few suppliers, the price will tend to rise; if the supply exceeds the demand, the price may fall. In addition, the price of raw materials is also a major factor. If the price of raw materials is high, the cost of 5-amino-5-cyanopyrazine will increase, and its market price will also rise accordingly.
And different suppliers and different quality specifications have different prices. The better price is high, and the second price is low. To know the exact price, you need to consult the supplier of chemical raw materials and compare the quotations of different merchants to get a more realistic price. In addition, the chemical market is changing, and prices rise and fall from time to time, so it is difficult to get a temporary price, and it is difficult to prevail for a long time.
