The synthesis of 7-chloro-3-methyl-8-quinoline carboxylic acid is related to the technique of chemical preparation. This synthesis method is obtained by chemical experts after repeated research and many attempts.
In the past, if Fang family wanted to obtain this compound, they first chose suitable starting materials. It often starts with quinoline derivatives with a specific structure, whose structure is like the cornerstone of building a mansion, laying the foundation for synthesis. Then, a halogenation method is applied. Under appropriate reaction conditions, chlorine atoms are introduced. Among them, the choice of reaction temperature, pressure, and solvent is the key. If the temperature is too high or side reactions are clustered, if it is too low, the reaction will be slow or even stagnant. The nature of the solvent is related to the solubility of the reactants and the rate and direction of the reaction.
After the chlorine atom is introduced, the methylation step is carried out. This step requires the use of special methylating reagents and strict control of all elements of the reaction. The amount of reagents and the reaction time must be precisely controlled. If the methylating reagent is excessive or causes excessive methylation, the product is impure; if the amount is small, the methylation is incomplete and it is difficult to obtain the target product.
Furthermore, in the synthesis process, separation and purification techniques are also indispensable. Due to the complex reaction system, the product is often mixed with impurities. It is necessary to separate the target product from impurities by recrystallization, column chromatography, etc., to obtain pure 7-chloro-3-methyl-8-quinoline carboxylic acid. These many steps are interlinked and indispensable. All of them rely on Fang's profound chemical foundation and rich experimental experience to achieve this synthesis method.

The price of 7-chloro-3-methyl-8-quinoline carboxylic acid in the market is difficult to be fixed. The range of its price often changes due to multiple reasons.
This compound is widely used in the chemical industry, medicine and other fields. If you look at the chemical raw material market, its quality and quantity are abundant, and the price may be slightly lower; if you look at the fine pharmaceutical and chemical supply, due to strict requirements on purity, the price will increase.
In the past few years, the market situation has changed. The production of raw materials, the increase or decrease in demand, and the regulation of politics are all the reasons for the price movement. Early in life, raw materials are easy to obtain, and there are many producers. The supply exceeds the demand, so the price is low, per kilogram or only a few tens of gold. Later, due to the stricter environmental protection, several factories closed down, and the demand for production has not been reduced. The price has risen, and the price can reach hundreds of gold per kilogram.
Recently, although production has gradually resumed, the international situation, transportation costs, etc. also disturb its price. Generally speaking, in today's city, if the purity is ordinary, the price per kilogram may be between 100 gold and hundreds of gold; if the high-purity high-quality products, the price per kilogram may exceed 500 gold, or even higher. It is difficult to determine, and it must be judged according to real-time market conditions.

7-Chloro-3-methyl-8-quinoline carboxylic acid, this is an organic compound. Its storage conditions are quite important, which is related to the quality and stability of this compound.
To properly store this compound, the first priority is the drying of the environment. Because it is easy to interact with water vapor or cause deterioration in humid environments, it should be placed in a dry place, and the dryness of the environment can be maintained by desiccant.
Temperature is also a key factor. It should be stored in a cool place to avoid high temperature. High temperature can easily promote chemical reactions, cause structural changes, and affect its chemical properties. Generally speaking, refrigeration conditions at 2-8 ° C are preferred, which can effectively slow down its chemical change rate.
Furthermore, it is necessary to pay attention to the ventilation condition of the storage place. Good ventilation can avoid the accumulation of harmful gases, and prevent the quality of compounds from being affected by abnormal local temperature and humidity.
Packaging should also not be taken lightly. Sealed packaging should be used to prevent the intrusion of air, water vapor and other impurities. If it is packed in glass or plastic bottles, make sure that the bottle cap is tightly sealed. If it is packed in plastic bags, it should also have good sealing.
During storage, it should be stored separately from oxidants, acids, alkalis and other substances. Due to its active chemical properties, contact with the above substances may cause violent chemical reactions, resulting in danger. In short, the storage of 7-chloro-3-methyl-8-quinolinecarboxylic acid requires a dry, cool, and ventilated environment, suitable packaging, and reasonable partitioning to ensure its quality and safety.
