I don't know what the market is for 2 - Bromo - 5 - chloropyridine - 4 - carboxaldehyde. This compound is not a normal thing, and its quality is often affected by many factors.
First, the degree is very important. If its degree is very high, it will be high enough for scientific research. If you want to use it in the synthesis or research of refined chemicals, you need something that needs to be high, and the supplier must ask for it. Because of its improvement process, it requires exquisite technology and multiple steps, and the cost is high.
Second, the demand for this product also affects the price. If the market is in high demand for this product, such as a new research product that needs a lot, and the supply is limited, it will rise. On the contrary, if the demand is weak, the supply is sufficient, and the cost of production is reduced.
Third, the cost of production also affects the price. The cost of raw materials, the method of synthesis, and the cost of production are all among them. If the raw materials are rare and available, or the synthesis step is complex, it requires a special price, and the price is not cheap. If it can be produced in a large scale, the cost of production may be reduced.
Fourth, the difference between suppliers also makes the price different. Different suppliers have different prices due to factors such as technology, cost control, and branding. Well-known big brands, because of their trust and quality, or higher than small.
If you want to know the market, you need to identify suppliers and compare them to get a rough estimate. Or you can check the product trading platform and industry report to see the market. However, it often floats, and you need to make a note to get the latest update.

2-Bromo-5-chloropyridine-4-formaldehyde is an important compound in organic chemistry. Its storage conditions are really related to the stability and quality of this compound, and need to be carefully studied.
This compound has active chemical properties and is extremely sensitive to many elements of the storage environment. First, temperature is crucial. It should be stored in a cool place to prevent excessive temperature from causing it to decompose or causing unnecessary chemical reactions. If placed in a high temperature environment, its molecular structure may change, and aldehyde groups, bromine atoms, and chlorine atoms may all participate in the reaction, which may damage the purity and integrity of the compound. Therefore, in a low temperature environment, generally speaking, between 0 ° C and 10 ° C. This temperature range can effectively reduce the active level of molecules and delay possible deterioration.
Second, humidity cannot be ignored. This material is susceptible to moisture, water vapor or interaction with molecules, triggering reactions such as hydrolysis, and changing its chemical composition. Therefore, it must be stored in a dry place. It is better to maintain the dryness of the environment by means of auxiliary means such as desiccants, and control the relative humidity below 40%.
Furthermore, light will also affect it. Light can provide energy, stimulate molecular reactions, and cause degradation or isomerization. Therefore, 2-bromo-5-chloropyridine-4-formaldehyde should be stored in a dark place, such as a brown bottle, or in a dark place to avoid adverse reactions caused by light.
In addition, the choice of storage containers is also particular. Chemically stable materials, such as glass or specific plastic materials, should be used to prevent chemical reactions with the container and ensure that the quality of the compound is not affected by the container.
In summary, 2-bromo-5-chloropyridine-4-formaldehyde should be stored in a cool, dry, dark place, choose a suitable storage container, and strictly control the temperature and humidity, so as to ensure the stability and purity of this substance during storage.
