One of them can be prepared from 8-hydroxyquinoline through a specific formylation reaction. In this case, a combination of hexamethyltetramine (urotropine) and acid is often used as a reagent. First, 8-hydroxyquinoline is mixed with hexamethyltetramine in an appropriate ratio, and heated in a specific solvent, such as glacial acetic acid. In this process, hexamethylenetramine decomposes in an acidic environment, releasing the active formyl group, and then reacts with the 2-position of 8-hydroxyquinoline to generate 8-hydroxyquinoline-2-formaldehyde.
Second, there are also people who use 8-hydroxyquinoline-2-carboxylic acid as raw material. It is first converted into the corresponding acid chloride, and then reduced to formylation.

8-Hydroxyquinoline-2-formaldehyde is an important substance in the field of organic compounds. However, its market price is difficult to determine, and it is deeply influenced by multiple factors.
First, the cost of production is a key factor. The price of raw materials accounts for a large proportion of the production cost of 8-hydroxyquinoline-2-formaldehyde. If the raw materials required to prepare this compound are scarce and difficult to find, or its mining and refining costs are high, the production cost of 8-hydroxyquinoline-2-formaldehyde will rise, thereby pushing up the market price. The equipment, energy consumption and labor costs required in the production process also have a great impact on the cost. Advanced production technology may improve production efficiency and reduce energy consumption, but the upfront equipment investment is also quite large, and these costs will be reflected in the product price.
Second, the supply and demand relationship in the market also affects its price. If the market demand for 8-hydroxyquinoline-2-formaldehyde is strong at a certain time, such as in the fields of medicine and materials science, the amount of it has increased greatly, and the supply is relatively scarce, and the supply is in short supply, the price will rise. On the contrary, if the market demand is weak, and there are many manufacturers, the supply is excessive, and the price may fall in order to seek sales.
Third, the purity and quality of the product are closely related to the price. In many high-end application scenarios, such as precision chemical synthesis, drug research and development, the purity of 8-hydroxyquinoline-2-formaldehyde is extremely high. The production of high-purity products is difficult and requires more complex purification processes, so the price is higher than that of ordinary purity products.
Fourth, the macroeconomic situation, policies and regulations, and transportation costs will also affect its price. The economic situation is good, the market is full of vitality, and the price may rise; otherwise, it may decline. Stringent environmental protection policies may cause enterprises to increase environmental protection inputs and increase production costs, which in turn affects prices. The increase or decrease in transportation costs will also be reflected in the end point product price.
In summary, in order to know the exact market price of 8-hydroxyquinoline-2-formaldehyde, it is necessary to comprehensively consider the above factors and pay close attention to the changes in market dynamics.
