The synthesis method of 5-nitro-6-methyl-2-pyridinecarboxylic acid, although the ancient book "Tiangong Kaiwu" does not directly describe the synthesis of this specific compound, the chemical theory can be cited as a lesson.
To make this substance, you can first find suitable pyridine substrates. Thinking in ancient ways, or starting from natural pyridine-containing substances, after ingenious extraction and purification, the basic pyridine raw materials are obtained.
Then, nitro is introduced at a specific position in the pyridine ring. In ancient methods, although there is no advanced nitrification reagent today, but Kesi uses nitrate-containing substances such as saltpeter to skillfully mix with acids and control temperature to simulate the nitrification environment. It is necessary to carefully adjust the temperature and material ratio to prevent excessive nitrification or side reactions.
As for the introduction of methyl groups, or active methylation reagents can be found, under appropriate conditions, the methyl groups are connected to the pyridine ring. This process requires consideration of the reaction medium and catalysts to promote the anterograde reaction.
During the synthesis, each step needs to be carefully controlled, and the reaction phenomena, such as color, odor, and state changes, need to be fine-tuned according to this condition. After each step of the reaction is completed, it is separated and purified, such as crystallization, distillation, extraction, etc., to obtain pure 5-nitro-6-methyl-2-pyridinecarboxylic acid. Although it is difficult to match the accuracy of the present with the ancient method, the way of thinking may open up a new way of synthesis.

5-Nitro-6-methyl-2-pyridinecarboxylic acid, this is a chemical substance. It varies in the market price range, often due to quality, purity, supply channels, purchase quantities and market fluctuations.
Looking at the trading situation of chemical products in the past, if the purity is ordinary and purchased in small batches, the price per gram may be in the tens of yuan. However, if the purity is very high, reaching the experimental level or higher standards, the price will rise sharply, or more than 100 yuan per gram.
If it is a large-scale industrial purchase, considering the economies of scale, the unit price may be significantly reduced. For example, if you purchase several kilograms or more at one time, the price per gram may be reduced to ten yuan or even lower.
However, the chemical market is changing, and many factors such as raw material prices, production process improvements, and market supply and demand trends can cause prices to fluctuate greatly. Therefore, to know the exact price range, it is recommended to consult chemical product suppliers and distributors for details, or explore real-time market conditions on professional chemical trading platforms.

5-Nitro-6-methyl-2-pyridinecarboxylic acid is an organic compound with active properties and should be stored with caution.
The first to bear the brunt should be a cool place. This compound is easy to decompose when heated, and if the temperature is too high, it may cause a chemical reaction and cause it to deteriorate. If it is placed in a high temperature, the molecular structure may be damaged, which affects its quality and performance. Therefore, it should be stored in a place with a constant temperature and a low temperature, such as a cool warehouse, to ensure its stability.
Furthermore, a dry environment is indispensable. It is hygroscopic and easily deliquescent in contact with water. After deliquescence, it may react with water to change its chemical composition. I still remember the past, when this object was stored in a humid place, it was not long before its properties changed, and its effectiveness was not as good as before. Therefore, it is necessary to ensure that the storage place is dry, and a desiccant can be placed next to it to absorb moisture.
Preservation away from light is also key. This object is sensitive to light, and under light, it may cause luminescent chemical reactions. Such as long-term exposure to light, or cause it to change color and decompose. Just like the ancient treasures, it was often placed in a dark room to prevent damage. Similarly, 5-nitro-6-methyl-2-pyridinecarboxylic acid should be stored in a brown bottle to avoid light and be properly stored.
In addition, it should also be stored separately from oxidizing agents and reducing agents. Due to its active chemical properties, contact with the above substances may cause severe reactions, and even cause explosions and other hazards. Be sure to strictly follow the rules for storing chemical substances, classify and place them properly, and prevent problems before they occur. In this way, the quality and safety of 5-nitro-6-methyl-2-pyridinecarboxylic acid can be guaranteed.
