The synthesis method of 4-hydroxy-6-methyl-3-pyridinecarboxylic acid has been investigated throughout the ages. The first method is to take a pyridine derivative as the starting material and undergo a halogenation reaction to introduce a halogen atom at a specific position. Then, by means of a nucleophilic substitution reaction, the halogen atom is replaced by a reagent containing a hydroxyl group to obtain a pyridine intermediate containing a hydroxyl group. Subsequently, through the methylation step, the methyl group is introduced at a suitable check point, and then through the oxidation reaction, the carboxyl group is precisely constructed, and the final product is 4-hydroxy-6-methyl-3-pyridinecarboxylic acid.
Furthermore, there are those who use another type of compound as the starting material. The pyridine ring structure is first constructed by cyclization reaction. During the reaction process, the reaction conditions are skillfully adjusted to make the cyclization check point and the distribution of substituents conform to expectations. After that, the substituents on the ring are modified, hydroxyl groups are introduced by hydroxylation reaction, and methyl groups are introduced by specific methylation reagents. Finally, 4-hydroxy-6-methyl-3-pyridinecarboxylic acid is successfully prepared by carboxylation reaction.
Another synthesis method is to start from simple and easy-to-obtain raw materials and gradually splice molecular fragments through multi-step reactions. First, the fragments containing the basic structure of the pyridine ring are synthesized, and then hydroxyl groups, methyl groups and carboxyl groups are introduced in turn through functional group transformation. In this process, it is necessary to carefully control the conditions of each step of the reaction, such as temperature, pH, catalyst type and dosage, etc., to ensure that the reaction proceeds according to the expected path to obtain high-purity 4-hydroxy-6-methyl-3-pyridinecarboxylic acid.
Different synthesis methods have their own advantages and disadvantages. According to actual needs, consider factors such as raw material cost, difficulty of reaction conditions, product purity and yield, and choose the best one.

4-Hydroxy-6-methyl-3-pyridine carboxylic acid, the price of this product in the market is not easy to say. The change in its price is affected by various factors.
First, it is related to the difficulty of preparation. If the preparation method is complicated, requires all kinds of exquisite steps, rare raw materials, and the yield is not high, or requires exquisite equipment and harsh conditions, its price will be high. On the contrary, if the preparation method is simple, the raw materials are common and easy to buy, and the yield is quite good, the price may be slightly cheaper.
Second, the supply and demand of the market is also the main reason. If there is a large demand for this product in the fields of medicine, chemical industry, etc., and there are few suppliers, the price will rise. If there is little demand and abundant supply, the price may drop.
Third, the price of raw materials also has an impact. If the price of raw materials is high, the cost of this product will increase, and its price in the market will also rise. If the price of raw materials falls, the cost will decrease, and the price may decrease.
Fourth, the state of competition in the industry should not be ignored. There are many suppliers in the city, and the competition is fierce. If there are few suppliers, it is almost a monopoly, and the price may be controlled by them, it will remain high.
As for the exact price, you need to consult the supplier of chemical raw materials and the seller of reagents, and the price varies depending on time and place. Or at a certain time and place, due to changes in supply and demand, changes in costs, prices rise and fall suddenly. Therefore, if you want to know the real-time market price, you should carefully observe the market situation and inquire from many parties.

For 4-hydroxy-6-methyl-3-pyridinecarboxylic acid, many matters need to be paid attention to during storage and transportation.
First words storage, this compound should be placed in a cool, dry and well-ventilated place. Because of the cool environment, it can avoid changes in its properties caused by excessive temperature. If it is overheated, it may cause decomposition and deterioration. The dry place can prevent it from moisture, because it may have a certain degree of moisture absorption, and the purity and quality may be affected after moisture. Well-ventilated can make the gas in the storage space flow smoothly and avoid the accumulation of harmful gases. At the same time, it should be stored separately from oxidants, acids, bases, etc. This is determined by its chemical properties. If it is mixed with the above substances, it is easy to cause chemical reactions, or cause fire, explosion and other hazards. And the storage place must be kept away from fire and heat sources to prevent fire.
As for transportation, it is necessary to strictly abide by the relevant regulations on the transportation of dangerous chemicals. Before transportation, it should be properly packaged, and the packaging materials used must be able to effectively protect the compound and avoid package damage due to collision, friction, etc. During transportation, the vehicle should be equipped with the corresponding variety and quantity of fire protection equipment and leakage emergency treatment equipment. When driving, it is necessary to prevent exposure to the sun, rain, and high temperature. If the package is damaged or leaked during transportation, emergency measures should be taken immediately. For example, quickly evacuate personnel from the leaked contaminated area to a safe area, isolate them, and strictly limit access. Emergency personnel must wear self-contained positive pressure breathing apparatus and anti-acid and alkali work clothes. Do not let leaks come into contact with combustible substances. Small leaks can be washed with a large amount of water, diluted with washing water and put into the wastewater system; large leaks need to be built embankments or excavated for containment, and transferred to a tanker or a special collector for recycling or transportation to a waste treatment site for disposal. In this way, storage and transportation are guaranteed to be safe.
