The synthesis of 2-pyrazinecarboxylic acid is an important topic in organic synthetic chemistry. There are many and ingenious methods for its synthesis.
First, it can be started by nitrogen-containing heterocyclic compounds. If pyrazine is used as raw material, it can be obtained by oxidation reaction. Among the oxidizing agents, strong oxidizing agents such as potassium permanganate and potassium dichromate are commonly used. Under suitable reaction conditions, a specific position of pyrazine is oxidized, and then carboxyl groups are introduced to form 2-pyrazine carboxylic acid. However, attention should be paid to the selectivity of the reaction in this way to prevent the product from being impure due to excessive oxidation.
Second, halogenated pyrazine is used as the starting material. After treatment with metal-organic reagents such as Grignard reagent or lithium reagent, and then reacting with carbon dioxide, 2-pyrazine carboxylic acid can also be obtained. Halogenated pyrazine interacts with metal reagents to form an active intermediate. This intermediate has nucleophilic properties for carbon dioxide. After the two are combined, the carboxyl group is formed after hydrolysis. This process requires strict reaction conditions, and the preparation of metal reagents and the anhydrous and anaerobic environment of the reaction need to be strictly controlled.
Third, the Hoffmann degradation reaction of amides. The amide containing pyrazine structure is first synthesized, and then treated with bromine or chlorine under basic conditions. After rearrangement reaction, the amide group is converted into an amino group, and the carbon atom of the carbonyl group is lost. If the initial amide structure is well designed, 2-pyrazine carboxylic acid derivatives can be generated, and then the target product can be obtained after appropriate modification.
Fourth, some microbial conversion methods can also synthesize 2-pyrazine carboxylic acid. Specific microorganisms have unique enzyme systems that can catalyze the conversion of specific substrates. Microorganisms that can act on pyrazine-related substrates are screened out. Under suitable fermentation conditions, the enzymes in microorganisms can catalyze the formation of 2-pyrazine carboxylic acids from the substrates. This biosynthesis method has the advantages of green and mild, but factors such as microbial culture and substrate specificity limit its large-scale application.
The above synthesis methods have their own advantages and disadvantages. The synthesis needs to be based on actual needs, considering factors such as the availability of raw materials, the difficulty of reaction conditions, product purity and yield, and choosing the optimal method to achieve the purpose of synthesizing 2-pyrazine carboxylic acid.

The price range of 2-pyrazine carboxylic acid in the market is difficult to say exactly. This is due to the influence of many factors, resulting in fluctuations in its price state.
Looking at its raw materials, if the origin and output of the raw materials change, or due to weather, geographical location, and human affairs, the price of raw materials will rise and fall, then the price of 2-pyrazine carboxylic acid will also fluctuate. And the method of preparation, the simplicity of the process, and the level of cost are all closely related to the price. The complicated and sophisticated process, although the product quality is high, the cost is also high, and the price is not cheap; the simple method, although the cost is reduced, the quality or poor, and the price is also different.
Furthermore, the trend of market supply and demand is like an invisible giant hand, which controls the price. If there are many seekers, but there are few suppliers, the price will rise; if the supply exceeds the demand, the price will be suppressed. In addition to the competition situation, the number and strength of the same industry also make the price change. Businesses compete for market share, or there is a game of price.
There are policies and regulations, and there are many restrictions and guidance in the production and sales links, which are also factors affecting the price. To sum up, in order to know the exact price range of 2-pyrazine carboxylic acid, it is necessary to consider the current situation in detail, and it is difficult to generalize the price range.
