The synthesis method of 2-methyl-3-nitropyridine-6-carboxylic acid has been known in ancient times and has been recorded in many books. Today, it is described in ancient methods, hoping to solve the confusion.
First, it can be started by the corresponding pyridine derivative. With a suitable pyridine substrate, methyl is introduced through methylation reaction. In this step, it is crucial to select a suitable methylation reagent. Common methylation reagents, such as iodomethane, dimethyl sulfate, etc. Under specific reaction conditions, the pyridine substrate is fully reacted with the methylation reagent to achieve the purpose of introducing methyl at a specific position in the pyridine ring.
Then, nitration reaction is carried out. Select the appropriate nitrification system, such as mixed acid (mixture of nitric acid and sulfuric acid), and carefully control the reaction temperature, time and other conditions. Nitric acid is catalyzed by sulfuric acid to produce nitroyl positive ions. This active species attacks the pyridine ring and introduces nitro groups at specific positions to form pyridine intermediates containing methyl groups and nitro groups.
Finally, the target product is obtained by carboxylation. 2-methyl-3-nitropyridine-6-carboxylic acid. Carbon dioxide can be used as the carboxyl source and reacted in a specific solvent in the presence of a metal catalyst and suitable ligands. Metal catalysts such as palladium and nickel, which cooperate with ligands to promote the carboxylation reaction between intermediates and carbon dioxide, thereby successfully constructing the carboxyl structure of the target molecule.
The synthesis path needs to be carefully adjusted according to the actual situation. The conditions of each reaction step, such as reagent dosage, temperature, reaction time, etc., are all related to the yield and purity of the product. Only fine control can achieve ideal results.

I look at your question, but I am inquiring about the price of 2-methyl-3-nitropyridine-6-carboxylic acid in the market. However, this price often changes due to many reasons, and it is difficult to determine.
Looking at the market conditions in the past, the price of this compound may be determined by raw materials, supply and demand, and the difficulty of preparation. If the raw materials are abundant and easy to make, and the supply exceeds the demand, the price may be cheap; on the contrary, if the raw materials are thin, difficult to make, and there are many in need, the price will be high.
Check "Tiangong Kaiwu", although there is no such chemical to determine the price, it is possible to refer to the change in the production system and price of the chemical. The price of the goods made by Fu Baigong depends on the simplicity of the product and the wide range of use. Such as 2-methyl-3-nitropyridine-6-carboxylic acid, if it is used in rare industries, it is not easy to produce, and the price is high; if it is a commonly used material, it is convenient to make, and the price is flat.
If you want to know the exact price now, you can consult the chemical raw material market, online chemical trading platform, or ask various suppliers to get the current price. However, this price is not constant, and the market situation changes, so you need to pay attention to it in real time.

The existence of 2-methyl-3-nitropyridine-6-carboxylic acid should be avoided due to its properties. Its properties are mostly generated by the structure. 2-methyl and 3-nitro groups are associated with the groups of pyridine-6-carboxylic acid, causing it to have specific chemical activities.
When it exists, it is the first to avoid heat. Heat can easily promote the rapid increase of its molecules, or cause chemical reactions and cause deterioration. If it is exposed to high temperature, the nitro group may undergo unstable changes and cause decomposition, etc., which will damage its purity and quality. Therefore, it should be placed in a cool place. If stored indoors, the room temperature should not exceed 25 ° C, such as in summer, or with air conditioning and other temperature control.
It also needs to be moisture-proof. Its molecules may be hydrophilic, because they contain carboxyl groups and other groups. Moisture is easy to interact with carboxyl groups, or react with hydrolysis and other reactions, which can damage its structure. It should be stored in a dry place. It can be stored and disposed of desiccants, such as silica gel, to absorb the surrounding moisture and keep it dry.
Furthermore, it is also necessary to avoid light. Light has energy, or induces photochemical reactions. The nitro groups and pyridine rings of this compound are sensitive to light, and under light, they may cause structure rearrangement, bond breakage, etc., which lose their inherent characteristics. Store in opaque containers, such as brown bottles, away from direct sunlight and strong artificial light sources.
Also, it should not be co-stored with reducing substances. Because it contains nitro groups, it is oxidizing, and in case of reducing agents, or severe redox reactions, causing danger, such as fire, explosion, etc. Therefore, when stored, it must be placed separately to ensure safety.
In general, when 2-methyl-3-nitropyridine-6-carboxylic acid is stored, it should be cool, dry, and protected from light, and should be avoided from coexistence with reducing substances to ensure its stability and long-term survival.
