The method of synthesizing 6-methyl-5-nitropyridine-2-carboxylic acid can be achieved by multi-step reaction.
The first step is usually to use suitable pyridine derivatives as starting materials. If 2-methyl pyridine is selected, due to its methyl activity, nitro groups can be introduced through nitration reaction. Under suitable reaction conditions, the mixed acid of concentrated nitric acid and concentrated sulfuric acid is used as the nitrifying reagent to heat the reaction. This process requires fine regulation of the reaction temperature, time and reagent ratio to prevent excessive nitrification. Generally, the temperature is controlled in the low temperature range, and the reaction number can be selectively introduced into the 5-position to obtain 5-nitro-2-methylpyridine.
Next, the obtained 5-nitro-2-methylpyridine is carboxylated. The usual method is to use carbon dioxide as the carboxyl source and react in the presence of a strong base and a specific catalyst. For example, metal-organic reagents, such as butyl lithium, first react with 5-nitro-2-methylpyridine to generate corresponding lithium salts, and then pass into carbon dioxide. After hydrolysis, 6-methyl-5-nitropyridine-2-carboxylic acid can be obtained. In this step, factors such as reaction solvent, type and amount of base, and reaction temperature have a significant impact on the reaction yield and product purity.
There are other synthesis paths. For example, the pyridine ring is modified first, a suitable substituent is introduced, and then converted into the target product through a series of reactions. However, no matter what method, it is necessary to pay attention to the optimization of the reaction conditions, ensure the selectivity and yield of each step, and pay attention to the separation and purification of the product to obtain high purity 6-methyl-5-nitropyridine-2-carboxylic acid.

I think this 6 - Methyl - 5 - nitropyridine - 2 - carboxylic acid is an organic chemical substance. Its price in the market is difficult to determine, and its price often varies due to various factors.
First, the price of raw materials has a great influence. If the raw materials used in the synthesis of this acid are scarce or difficult to harvest, the price will be high, and the price of this acid will also rise; if the raw materials are abundant and easy to obtain, the price will be flat.
Second, the method of preparation is also important. If the preparation requires complicated processes and rare reagents are used, the energy consumption is high, the cost is greatly increased, and the price is not cheap; if there is a simple and good method, the cost will drop and the price will also fall.
Third, the market supply and demand situation affects its price. If there are many applicants, there are few suppliers, and those who are merchants must raise their prices to make a profit; if there is an oversupply, the merchants will ship, or reduce the price to promote sales.
Fourth, the quality level is also the main reason. Those with high purity and excellent quality should be higher than those who are ordinary.
According to past market conditions, the price of this acid may be between tens and hundreds of yuan per gram. However, this is only a rough estimate, not an exact number. The market conditions are constantly changing, and if you want to know the real-time price, you must consult the supplier of chemical raw materials, the seller of chemical reagents, or the chemical trading platform to obtain an accurate price.

6-Methyl-5-nitropyridine-2-carboxylic acid is a kind of organic compound. Its storage conditions are crucial, which is related to the stability and quality of this compound.
