2% 2C6-dideuterium-3-fluoromethylpyridine, this is a unique organic compound. Its physical properties are quite elegant.
Looking at its state, under room temperature and pressure, it often takes the form of a liquid state. The formation of this state is due to the specific situation of the intermolecular force. There is van der Waals force between molecules, or there is a hydrogen bond effect, so that the molecule can be maintained in the liquid category.
As for the color, it is mostly colorless and transparent, just like clear water, pure and free of variegation. This colorless property is of great significance in many application scenarios, and it can avoid the interference of color on related reactions or detection.
Smell it, it has a special smell. This unique odor may be the result of the interaction of the structure of the pyridine ring and the substituents such as fluoromethyl and deuterium atoms. Although the odor is special, its characteristics also provide an important basis for identification and operation in specific industrial environments or laboratory operations.
When it comes to boiling point, due to the introduction of dideuterium and fluoromethyl, it changes compared with ordinary pyridine derivatives. The mass of the dideuterium atom is greater than that of the hydrogen atom, which enhances the intermolecular force; the high electronegativity of fluoromethyl also affects the intermolecular force, causing its boiling point to appear to rise. The specific boiling point value is based on accurate experimental determination, but it is roughly in a specific temperature range. The definition of this range is extremely critical for its separation, purification and storage operations.
Its melting point is also affected by structural changes. Dideuterium and fluoromethyl change the molecular accumulation mode and action force, and the melting point may be different from that of conventional similar substances. The determination of the melting point is a key parameter for the transformation of solid and liquid states, and is indispensable for the phase control of substances and related process applications.
In terms of solubility, due to the polarity of molecules, it shows a certain solubility in some organic solvents. Pyridine rings have a certain polarity, and fluoromethyl also affects the overall polarity of molecules, so that in organic solvents such as alcohols and ethers, it can achieve a certain degree of dissolution according to the principle of similar miscibility. This property is of great significance in the selection of reaction media and product separation in organic synthesis.

2% 2C6 -dideuterium-3 -fluoromethylpyridine, this is an organic compound. According to its chemical properties, the stability is acceptable.
Geinpyridine ring is aromatic, and there is a conjugated system in its structure, which gives the molecule a certain stability. The π electron cloud of the aromatic ring is highly delocalized, which makes the whole molecule energy reduced and is not easy to be attacked by external reagents.
And the deuterium atom of 2,6 positions is replaced. Although deuterium and hydrogen are isotopes, the deuterium-carbon bond is more stable than the hydrogen-carbon bond due to the difference in mass and vibration frequency, which enhances the stability of the molecular structure to a certain extent. Furthermore, the fluoromethyl substituent at the 3rd position has extremely high electronegativity and has a strong electron-absorbing induction effect (-I effect). Although this effect will reduce the electron cloud density of the pyridine ring and affect the electrophilic substitution reactivity, on the other hand, by adjusting the electron cloud distribution within the molecule, the charge distribution of the whole molecule is more reasonable, which improves the stability of the molecule to some extent.
However, its stability is not absolute. Under certain conditions, its structure will also change in the case of strong oxidizing agents, strong acids, strong bases, or extreme environments such as high temperature and high pressure. For example, under strong oxidation conditions, the pyridine ring may be oxidized to open the ring; in the action of strong acids or bases, substituents such as fluoromethyl may undergo hydrolysis, substitution and other reactions, thereby changing the chemical structure and properties of the compound. However, in general conventional storage and common chemical reaction environments, 2% 2C6-dideuterium-3-fluoromethylpyridine can usually maintain a relatively stable chemical state.

2% 2C6-dideuterium-3-fluoromethylpyridine is an organic compound with special isotope labels. The synthesis method is as follows:
Pyridine derivatives should be selected as the starting material, because the pyridine ring structure is compatible with the target product. If the common 3-methylpyridine is used as the starting material, the methyl group needs to be halogenated first. 3-methylpyridine can be reacted with a halogen (such as bromine) in the presence of light or an initiator to generate 3-halomethylpyridine. This halogen atom can be used as a key reaction check point later.
When introducing deuterium atoms, in view of the cost and reactivity of deuterated reagents, suitable deuterated solvents or deuterated reagents should be used. For example, in deuterated methanol (CD-OD) as a solvent, the α-hydrogen of 3-halomethylpyridine can be replaced by deuterium atoms under the action of strong bases (such as potassium tert-butyl alcohol). After the hydrogen is taken from the strong base, the formed carbon negative ions can combine with deuterium in the deuterated solvent, thereby introducing deuterium atoms. However, this reaction condition needs to be precisely controlled to prevent excessive deuteration or other side reactions.
Introduction of fluoromethyl is a key step. Fluoromethylation reagents can be prepared first, such as fluoromethylation reagents by reacting paraformaldehyde, hydrogen fluoride with suitable reducing agents. Afterwards, 3-halomethylpyridine is coupled to the fluoromethylating reagent under the action of appropriate catalysts (such as palladium catalysts) and ligands. In this process, the choice of catalyst and ligand is extremely critical, which will affect the reactivity and selectivity. Appropriate ligands can enhance the binding force between the catalyst and the substrate, improve the reaction efficiency, and promote the precise connection of fluoromethyl to the 3-position of the pyridine ring.
After the reaction is completed, the product needs to be separated and purified. Due to the complex reaction system, it may contain unreacted raw materials, by-products, etc. Column chromatography is commonly used to separate the product and impurities according to the difference in the partition coefficient between the stationary phase and the mobile phase. Select a suitable eluent to make the product flow out before the impurities, collect the eluent containing the pure product, and steam to remove the solvent to obtain a pure 2% 2C6-dideuterium-3-fluoromethylpyridine. The whole synthesis process requires strict anhydrous and anaerobic operation, and the reaction temperature, time and material ratio are controlled to ensure the yield and product purity.

The price of 2% 2C6-dideuterium-3-methoxypyridine in the market is difficult to determine. Its price varies widely and narrowly due to many reasons.
First, it is related to the difficulty of its preparation. If the preparation method is complicated, the materials used are rare, and the labor hours required are quite long, the price will be high; if it is easy to make, the materials are often labor-saving, and the price will be low.
Second, it depends on the supply and demand of the city. If there are many people who want it, but there are few suppliers, if a certain industry is suddenly prosperous, they need it as a material to produce other products, and the supply is in short supply, and the price will rise; conversely, if the supply exceeds the demand, the producers will compete for sales, and the price will drop.
Third, it is related to quality. The higher the purity, the less impurities it contains, the better the quality, and the higher the price; if the quality is impure, the price is low.
Fourth, regional differences also have an impact. In prosperous commercial ports, with convenient transportation and smooth trade, the price may be relatively easy; in remote places, transportation is difficult, costs increase, and the price may be higher.
Generally speaking, the price of this product in the market varies from tens to hundreds of dollars per gram. However, this is only an approximate number, and the actual price often fluctuates greatly due to changes in time, place, and situation, making it difficult to have an accurate value. If you want to know the exact price, you must consult the merchants about the actual situation of the market.
