To prepare 5-hydroxy-pyridine-3-formaldehyde, the following method can be used.
First, pyridine is taken as the starting material. The pyridine ring is aromatic, and its nitrogen atom changes the density distribution of the ring electron cloud. Using pyridine as the group, a hydroxyl group and an aldehyde group are introduced through a specific reaction.
A suitable substituent can be introduced into the pyridine ring first with a suitable reagent, such as an electrophilic reagent under specific conditions, to pave the way for the subsequent introduction of hydroxyl groups and aldehyde groups. For example, a suitable halogenating reagent is used to react with it to halogenate the pyridine ring at a specific position. This halogen atom can provide a check point for the subsequent introduction of hydroxyl groups.
Then, the nucleophilic substitution reaction is used to react with halogenated pyridine with a hydroxyl-containing nucleophilic reagent, so that the halogen atom is replaced by a hydroxyl group to obtain a 5-hydroxypyridine derivative.
As for the introduction of aldehyde groups, suitable formylation reactions can be used. For example, with a suitable formylation reagent, under suitable catalyst and reaction conditions, the 5-hydroxypyridine derivative can be introduced into the aldehyde group at a specific position. The formylation reagent used needs to consider factors such as reactivity and selectivity to ensure that the aldehyde group is accurately introduced into the desired position and has minimal impact on existing groups such as hydroxyl groups.
During the whole process, the reaction conditions such as temperature, pressure, solvent, etc. need to be precisely regulated. Temperature affects the reaction rate and selectivity, and different stages of the reaction have different temperature requirements. Solvent selection is also critical, which needs to be able to dissolve the reactants without adversely affecting the reaction process. In this way, through multi-step reaction and fine regulation, the target product 5-hydroxy-pyridine-3-formaldehyde is expected to be obtained.

5-Hydroxy-pyridine-3-formaldehyde is an organic compound, and there are many key precautions to be paid attention to during storage.
First, pay attention to the temperature and humidity of the storage environment. This compound is quite sensitive to temperature and humidity, and both high temperature and high humidity environments may cause it to deteriorate. Therefore, it should be stored in a cool and dry place. The temperature should be maintained at 2-8 ° C, and the humidity should be controlled between 40% and 60%. This can effectively delay the rate of chemical change and ensure its stability.
Second, pay attention to the influence of light. The substance is easy to decompose when exposed to light, so be sure to take measures to avoid light when storing. You can choose brown glass bottles or opaque containers to prevent direct exposure to light, so as to reduce the risk of decomposition reactions caused by light.
Third, the material of the storage container is also crucial. Materials that are chemically stable and do not react with 5-hydroxy-pyridine-3-formaldehyde should be selected, such as glass, specific plastics, etc. Avoid using metal containers, as they may chemically react with compounds, which may change their chemical structure and properties.
Fourth, seal well. The compound is easy to interact with oxygen, moisture and other components in the air, so the storage container must be well sealed to prevent air from entering. You can add sealing gaskets or use sealants and other auxiliary means to enhance the sealing.
Finally, the storage area should be well ventilated to prevent the accumulation of volatile gases and reduce safety hazards. And it should be stored separately from other chemicals to avoid danger due to mutual reaction. In this way, 5-hydroxy-pyridine-3-formaldehyde can be properly stored to maintain its quality and stability.

5-Hydroxy-pyridine-3-formaldehyde, this product is in the market, its price is impermanent, due to many reasons. Looking at the past, the price of such things may vary depending on the difficulty of preparation, the amount of materials used, and the urgency of purchase.
If the preparation method is cumbersome, rare materials are required, and the technology is complicated, the price will be high. If the material is easy to take, simple to make, the price may be slightly flat. There are many buyers, and the supply is insufficient, and the price will also increase; if the supply exceeds the demand, the price will drop.
However, the price in the market is difficult to determine. In past transactions, there may be tens of gold per gram, and the price may vary greatly due to the quantity and quality. Those with large quantities may have excellent profits; those with pure quality must be higher than the regular product.
