Another synthesis method can be used. Starting from other compounds with suitable substituents, through multi-step transformation, the pyridine ring can be cleverly constructed, and chlorine, methyl and carboxyl groups can be introduced simultaneously. This approach requires an understanding of the reaction mechanism at each step and strict control of the reaction conditions in order to efficiently synthesize the target product. Each step of the reaction needs to be carefully monitored and optimized to ensure that the reaction progresses in the expected direction and obtains high purity 6-chloro-4-methylpyridine-2-carboxylic acid.

6-Chloro-4-methylpyridine-2-carboxylic acid is in the market, and its price range is difficult to determine. The change in its price is subject to many factors.
First, the price of the raw material is the main factor. If the price of the raw materials required for its preparation rises and falls, the price of the compound will also change accordingly. If the raw materials are easy to obtain and the price is average, the price of the finished product may be stable and low; if the raw materials are dilute and expensive, the price must be high.
Second, the preparation method is also very important to the workmanship. A good method of simple work can reduce its production and consumption, reduce its cost, and the price can also be close to the people; if the method is too complicated, expensive and time-consuming, the price may increase.
Third, the supply and demand of the city is also the key. If the demand is prosperous and the supply is small, the price will rise; if the supply exceeds the demand, the price will fall. And its use in medicine, pesticides and other industries is different, and the demand is also different, and the price will change accordingly.
Fourth, the competitive state of the city also has an impact. The industry, the competition is fierce, in order to occupy the market, or cut the price; on the contrary, the widow may control the quantity and raise the price.
To sum up the above reasons, the price of 6-chloro-4-methylpyridine-2-carboxylic acid may range from tens to hundreds of yuan per kilogram, but it is difficult to determine the exact number. The market conditions are ever-changing, and the price is also variable. To know the details, it is necessary to study the real-time market conditions and various factors.
