2-Amino-3-chloro-4-methylpyridine is one of the organic compounds. During storage and transportation, many matters must be paid attention to.
When it is stored, the first environment is dry. This compound can easily cause many chemical reactions in case of moisture, resulting in damage to its quality. A dry place must be selected to prevent the risk of moisture decomposition. Furthermore, the temperature needs to be properly controlled. It should be stored in a cool place to avoid hot topics. Due to high temperatures, its chemical properties may become active, and even decompose and explode.
And the storage place should be well ventilated. This compound may evaporate harmful gases. Good ventilation can reduce its concentration in the air and reduce the harm to the human body and the environment. At the same time, it must be stored separately with oxidizing agents, acids, alkalis and other chemicals. Because of its unique chemical properties, contact with them can easily cause violent reactions and endanger safety.

Transport personnel should be professionally trained and familiar with the characteristics of this compound and emergency response methods. During transportation, pay close attention to environmental factors such as temperature and humidity. In case of bad weather, corresponding protective measures should be taken. Therefore, when storing and transporting 2-amino-3-chloro-4-methylpyridine, care should be taken to ensure its safety and quality.

2-Amino-3-chloro-4-methylpyridine is an important organic compound, which is used in many fields, such as the synthesis of medicine, pesticides, materials, etc. However, its market price is complicated due to various factors, and it is difficult to generalize.
bear the brunt, and its price is affected by the production process. If the production process is advanced and mature, the conversion rate of raw materials is high, the production cost can be reduced, and the market price may stabilize. If the process is complex, multiple steps are required, and there are many side reactions, the loss of raw materials is large, the cost rises, and the price will remain high.
Furthermore, the fluctuation of raw material prices has a huge impact. The production of 2-amino-3-chloro-4-methylpyridine requires specific raw materials. If the supply of raw materials is tight and the price rises sharply, the cost of this compound will also rise, eventually causing market price fluctuations.
The relationship between supply and demand in the market is also critical. If the market demand for it is strong, such as the demand for this compound in the field of pharmaceutical research and development, but the supply is limited, merchants may raise prices to make more profits. On the contrary, if the supply exceeds the demand, merchants will sell inventory or reduce prices to promote.
Regional differences should not be underestimated. Prices vary depending on the level of economic development, transportation costs, tax policies, etc. In economically developed areas, the demand is large, and the price may be slightly higher; in remote areas, due to factors such as transportation costs, the price may also change.
In addition, product quality and purity have a significant impact on the price. High-purity products are mostly used in high-end pharmaceutical research and development, and the price is high; those with slightly lower purity are used in general industrial production, and the price is relatively low.
Overall, the market price of 2-amino-3-chloro-4-methylpyridine may range from tens to thousands of yuan per kilogram. The specific price depends on the above factors and real-time market conditions. When purchasing, be sure to conduct multiple surveys to compare prices and product quality with different suppliers in order to obtain reasonable prices and high-quality products.
