To prepare 2-fluoro-4-iodopyridine-3-formaldehyde, the following methods can be followed.
The starting material is selected from a suitable pyridine derivative, such as 4-iodopyridine-3-formaldehyde. Because its structure already has iodine and aldehyde groups, fluorine atoms need only be introduced at the 2nd position.
First, 4-iodopyridine-3-formaldehyde can be dissolved in a suitable aprotic polar solvent, such as N, N-dimethylformamide (DMF). The system needs to be at a low temperature, such as 0 ° C to 5 ° C, in a nitrogen-protected atmosphere, slowly add a base, such as sodium hydride (NaH). The function of the base is to take away the 2 hydrogen atoms on the substrate pyridine ring, so that the check point is negative, which is conducive to the subsequent nucleophilic substitution reaction.
Then, add a fluorinated reagent, such as Selectfluor reagent. Selectfluor reagent is a commonly used fluorine-containing reagent and can effectively provide fluorine positive ions. During the reaction, the fluorine positive ion attacks the 2 position of the base-activated pyridine ring to generate 2-fluoro-4-iodopyridine-3-formaldehyde. This reaction usually requires continuous stirring for several hours. The specific time depends on the reaction monitoring results. The reaction progress is often monitored by thin-layer chromatography (TLC).
After the reaction is completed, the reaction liquid is poured into ice water to quench the reaction. Subsequently, the product is extracted with an organic solvent such as dichloromethane. The combined organic phases are washed with water and saturated saline, dried with anhydrous sodium sulfate, and the solvent is evaporated to obtain a crude product.
The crude product is purified by column chromatography. A suitable silica gel column and eluent, such as a mixed solvent of petroleum ether and ethyl acetate, are selected. The ratio of the two is adjusted according to the polarity of the product to obtain high-purity 2-fluoro-4-iodopyridine-3-formaldehyde.
In addition, there are other methods. Or starting from 2-fluoropyridine, the aldehyde group is introduced first at the 3rd position and the iodine atom is introduced at the 4th position. However, in comparison, using 4-iodopyridine-3-formaldehyde as the starting material, the steps are simpler, the reaction selectivity is easier to control, and the target product with higher yield and purity can be obtained.

What I am asking you is about the market price of 2-fluoro-4-iodine-pyridine-3-formaldehyde. However, the price of this chemical often changes due to many factors, and it is difficult to have a fixed price.
The first to bear the brunt is the trend of supply and demand. If there is a strong demand for this product in the market and the supply is limited, the price will rise; on the contrary, if the supply is abundant and the demand is weak, the price will fall from there.
Furthermore, the cost of production is also the key. The price of raw materials, the simplicity of the production process, and the amount of energy consumption will all affect its cost. If the price of raw materials is high, or the cost increases greatly due to the complexity of the production process, the market price will also be higher.
The origin and quality also have a great impact on the price. Produced in different origins, due to differences in production conditions, the quality may be different. Those with high quality often have higher prices than ordinary ones.
And the state of market competition cannot be ignored. If there are many manufacturers producing this chemical in the market and the competition is fierce, it is a competition for market share, and the price may fluctuate.
In summary, in order to know the exact market price of 2-fluoro-4-iodine-pyridine-3-formaldehyde, it is necessary to gain real-time insight into many factors such as market supply and demand, cost changes, quality differences, and competition trends in order to make a more accurate judgment.

2-Fluoro-4-iodine-pyridine-3-formaldehyde is an organic compound, and its storage conditions are very critical, which is related to the stability and quality of the substance.
This substance should be stored in a cool place, because high temperature can easily cause its chemical properties to change, or cause decomposition and deterioration. The temperature of the warehouse should be maintained in a relatively cool state, which can effectively slow down the thermal movement of molecules and reduce the rate of chemical reactions.
A dry environment is also indispensable. The moisture in the air is easy to interact with the compound, or cause adverse reactions such as hydrolysis. Therefore, the storage place must be moisture-proof, and the environment can be maintained dry by means of desiccants.
Furthermore, it should be stored in a well-ventilated place. If the storage space is poorly ventilated, the volatile gases of the compound will accumulate, which may affect its own stability, and there are potential safety hazards, such as exposure to open flames or other excitation conditions, or cause danger.
This compound may have certain toxicity and irritation, so it must be stored away from fire and heat sources to avoid mixing with substances that are prone to reactions such as oxidants. At the same time, the storage area should be clearly marked to prevent accidental contact and misuse.
During the retrieval and storage operation, relevant personnel must strictly follow the safety operating procedures and wear appropriate protective equipment, such as gloves, goggles, etc., to prevent the compound from coming into direct contact with the human body and causing harm to personnel. In this way, the stability and safety of 2-fluoro-4-iodine-pyridine-3-formaldehyde during storage can be ensured.
