There are many different ways to synthesize 2-fluoro-5-formyl-3-methylpyridine. One of the common ones can be started by pyridine derivatives containing corresponding substituents. For example, 3-methyl-2-fluoropyridine is used as a raw material, and formyl groups are introduced through a specific oxidation reaction. The choice of oxidation reagents is very critical, and mild reagents such as the Swern oxidation system composed of DMSO and oxalyl chloride are often used. In a low temperature environment, the substrate is dissolved in a suitable organic solvent, such as dichloromethane, oxalyl chloride is added first, then DMSO is slowly added dropwise, and then kept at low temperature for a period of time to allow the reaction to proceed fully. This process requires careful control of temperature and reagent dropwise rate to prevent side reactions from occurring.
There are also 2-fluoro-3-methyl-5-halogenated pyridine as the starting material, by reacting with metal-organic reagents, such as lithium reagents or Grignard reagents, and then reacting with suitable carbonylation reagents, such as DMF, to introduce formyl groups. This method requires attention to the preparation and reaction conditions of metal-organic reagents to ensure that their activity is suitable, and the reaction system is anhydrous and oxygen-free to avoid the failure of the reagents.
Another method can be achieved by pyridine ring construction reaction from compounds containing fluorine, methyl and aldehyde precursors. For example, a specific nitrogen-containing, carbonyl-containing compound is cyclized under acidic or basic catalytic conditions to generate the target pyridine derivative. In this process, the type and dosage of catalysts, reaction temperature and time all have significant effects on the yield and selectivity of the reaction. Several experiments are required to optimize the reaction conditions to achieve the best synthesis effect.

2-Fluoro-5-formyl-3-methylpyridine, the properties of this product, let me tell you in detail.
Its shape is mostly white to light yellow solid, and it looks quite crystal clear. Under normal temperature, it exists stably, but when it encounters hot topics and open flames, it is dangerous, just like an undercurrent hidden under the appearance of calm.
Its melting point is within a specific range, and this value is a key indicator to define its physical properties. Due to the ingenious combination of fluorine, formyl and methyl groups in the molecular structure, it has unique solubility. In organic solvents, such as ethanol and dichloromethane, it can obtain a good dissolution effect, just like a fish gets water, and the molecules are free to shuttle in the solvent.
As for the boiling point, it also hovers in a certain range, which is related to the transformation of its state during the heating process. In the field of chemical synthesis, this substance is often a key intermediate due to the active formyl group in its structure, such as the cornerstone of a delicate pavilion.
And because of the presence of fluorine atoms, it endows molecules with different electronic effects and spatial effects, affecting their chemical reaction activity and selectivity, just like arranging unique dance steps for the dance of chemical reactions. Its smell may be slightly irritating, and it is necessary to be cautious when smelling, so as not to hurt the sense of smell. Such physical properties play a pivotal role in organic synthesis and drug research and development, and are an indispensable "sharp blade" in the hands of researchers.

2-Fluoro-5-formyl-3-methylpyridine, this is an organic compound. Its chemical properties are unique, containing fluorine, formyl and methyl groups, and each group interacts with each other to create many characteristics.
Let's talk about its reactivity first. Formalyl groups have high activity and are easy to participate in many reactions. For example, typical reactions of aldose can occur, such as acid catalysis with alcohols to form acetals. This reaction may help protect formyl groups or be used to construct more complex organic structures. It can also carry out oxidation reactions, which can be oxidized to carboxylic groups, and then a series of carboxylic acid derivatives can be derived, which are widely used in the field of organic synthesis.
Furthermore, although methyl is relatively stable, its electron-giving effect can affect the electron cloud density of the pyridine ring and change the activity and selectivity of the substitution reaction on the pyridine ring. Fluorine atoms are extremely electronegative, and their existence can enhance molecular polarity, which has a significant impact on the physical properties of compounds, such as boiling point and solubility. At the same time, fluorine atoms also affect the reaction check point, making the reaction more regioselectivity.
This compound may also react with nucleophiles. The carbon atom of the formyl group is an electrophilic center and is vulnerable to attack by nucleophiles. Nucleophiles or compounds containing atoms such as nitrogen, oxygen, and sulfur can generate new organic compounds through nucleophilic addition or nucleophilic substitution reactions. In addition, the pyridine ring itself is aromatic and can participate in various aromatic substitution reactions, such as electrophilic substitution reactions. Under suitable conditions, specific reagents can replace hydrogen atoms on the pyridine ring, thereby introducing other functional groups, expanding the structure and properties of compounds, and providing rich possibilities for organic synthesis and drug development.

I don't know the exact range of the market price of 2-fluoro-5-formyl-3-methylpyridine. The price of this compound often varies due to many factors.
First, manufacturers vary, and their cost control and process level are different, resulting in different product prices. Large factories may have lower costs and competitive prices due to economies of scale; small factories may have different prices if they have unique processes and high quality.
Second, purity has a great impact. High purity, difficult to prepare, high cost, and expensive; low purity, meeting general needs, may have relatively low prices.
Third, the market supply and demand relationship is the key. If the demand is strong and the supply is small, the price will rise; if the supply exceeds the demand, the price will drop.
Fourth, the purchase volume is also related. If the batch is large, the manufacturer may give a discount, and the unit price will be reduced; if you buy a small amount, the unit price will be high.
However, after searching the past data, it is difficult to find its specific price range. To know the exact price, you can consult chemical product suppliers, browse professional chemical trading platforms, or consult industry experts to get more accurate price information.
