The synthesis method of 2-chloro-5-methoxypyridine has been explored by many sages in the past, but now there are many important ones.
First, 5-methoxypyridine-2-amine is used as the starting material, and then reacted with cuprous chloride through diazotization. This is a classic method. First, take 5-methoxypyridine-2-amine, dissolve it in an appropriate amount of acid, slowly add sodium nitrite solution at low temperature, perform diazotization, and generate diazo salts. After adding cuprous chloride, the diazo group is replaced by a chlorine atom, and 2-chloro-5-methoxypyridine can be obtained. This process requires strict control of temperature and reaction time to prevent the growth of side reactions.
Second, 2-hydroxy-5-methoxypyridine is used as a substrate and prepared by chlorination reaction. Chlorination reagents such as phosphorus oxychloride can be selected and reacted under appropriate solvent and catalytic conditions. 2-hydroxy-5-methoxypyridine is mixed with phosphorus oxychloride, heated and refluxed, and the hydroxyl group is replaced by chlorine atoms. After the reaction is completed, the product is purified after post-treatment such as vacuum distillation and extraction. The key to this approach lies in the amount of chlorination reagent, the reaction temperature and the fine operation of post-treatment.
Third, starting from pyridine derivatives, it is synthesized by selective methoxylation and chlorination reaction. The methoxy group is first introduced into the specific position of the pyridine ring, which can be achieved by nucleophilic substitution and other reactions, and then chlorinated at another suitable position. For example, starting with a suitable pyridine halogen, the methoxy group is introduced by reacting with sodium methoxide under basic conditions, and then a suitable chlorination agent is selected to carry out chlorination, and the target product is isolated and purified. This route requires precise control of the selectivity of the reaction check point and the reaction conditions of each step.
The above methods have their own advantages and disadvantages. In practical application, when considering factors such as the availability of raw materials, cost, yield and product purity, choose the best one and use it to achieve the purpose of efficient synthesis of 2-chloro-5-methoxypyridine.

The price range of 2-chloro-5-methoxypyridine in the market is difficult to determine. The price of 2-chloro-5-methoxypyridine often varies due to many factors, such as the trend of supply and demand, the complexity of the process, the quality of the quality, the amount of purchase and the change of market conditions.
Looking at the past market conditions, the price fluctuation is not uniform. If the quality is high, and when blocking trade, the price may be relatively easy; if the demand is too much, or the production is limited due to the complexity of the process, the price may increase.
Under normal market conditions, the price of 2-chloro-5-methoxypyridine per gram is extrapolated from the price of similar chemicals in the past, or between a few and tens of yuan. However, this is only an approximate number and cannot be approved. If the purchase volume is large, the merchant may have a discount, and the price should be more appropriate.
And the chemical market is changing rapidly. The rise of new technologies and the guidance of policies can make the price change. To know the exact price, it is advisable to consult chemical raw material suppliers, traders, or check the real-time quotation of chemical product trading platforms to get a close price.

2-Chloro-5-methoxypyridine is also an organic compound. The storage conditions are particular about the nature and safety of this substance.
This substance should be stored in a cool and well-ventilated place. Because of the cool environment, it can slow down the rate of chemical changes and avoid adverse reactions such as decomposition and polymerization due to excessive temperature. Well ventilated, it can disperse harmful gases that may escape, ensure the safety of the storage environment, and avoid the risk of explosion caused by its accumulation.
Furthermore, it is necessary to keep away from fire and heat sources. These two are the key incentives for combustion and explosion. 2-Chloro-5-methoxypyridine may be flammable. In case of fire or heat source, it will explode instantaneously, endangering the surrounding area.
It should be separated from oxidants and edible chemicals, and must not be stored in a mixed manner. Oxidants have strong oxidizing properties and meet with 2-chloro-5-methoxypyridine, or cause a violent oxidation reaction, causing danger. Mixed with edible chemicals, if there is leakage, it can easily contaminate food supplies and endanger human health.
Storage places must be prepared with suitable materials to contain leaks. In case of leakage, it can be collected in time to reduce its pollution to the environment and prevent its spread from causing greater harm. The package should be sealed to avoid contact with the air. Oxygen, water vapor, etc. in the air, or react with it, can damage its quality.
When handling, it should be handled lightly to prevent damage to the package and container. If the package is damaged, 2-chloro-5-methoxypyridine leaks, which is a waste of resources and a safety hazard. Strictly observe these storage conditions to ensure the safety and quality of 2-chloro-5-methoxypyridine storage.
