3-Acetyl-2-methoxypyridine is one of the organic compounds. It has specific physical properties and is very useful in many fields such as chemical industry and medicine.
Looking at its properties, it is liquid under normal circumstances, and its color may be nearly colorless, or it may be very light yellow, with a clear texture, similar to the purity of glaze. Its smell is unique, with a fragrant rhyme, but it is different from the common floral and fruity fragrance. It has the unique smell of a chemical substance. It is neither pungent nor dull, but somewhere in between. Sniffing it carefully, it seems to be able to sense its internal chemical vitality.
When it comes to the boiling point, it is within a certain temperature range. This property makes it exist in a liquid state under specific conditions. If appropriate heat is applied, it can be converted into a gaseous state. The melting point is also a specific value. When cooled to this point, its state will slowly change from liquid to solid. The point of this state change needs to be carefully considered during its production, storage and use.
Furthermore, solubility is also an important physical property. In organic solvents, such as ethanol, ether, etc., it can well dissolve with each other, just like the water of fish, and fuses together. This is because the force between the organic solvent and the molecules of 3-acetyl-2-methoxypyridine is in harmony with each other, so it can be evenly dispersed. However, in water, its solubility varies, either a little or insoluble. This difference is due to the difference in molecular structure and polarity between water and the compound.
Its density is also a specific value, which may be different from that of water. When placed in water, or floating on the surface, or submerged in water, this characteristic is an important consideration when separating, mixing, etc. And its refractive index also has a unique value. When light passes through, it will change the propagation direction according to this specific parameter, which may be of special significance in the research and application of optics. In conclusion, the physical properties of 3-acetyl-2-methoxypyridine are interrelated and together determine their performance in different environments and processes, providing researchers and users with many clues and evidence to make good use of this compound.

The chemical properties of 3-acetyl-2-methoxypyridine are relatively stable under normal conditions. In its structure, the pyridine ring is aromatic, giving a certain stability to the molecule. Methoxy and acetyl groups also contribute to its stability. The
methoxy group has a electron supply effect, which can increase the electron cloud density on the pyridine ring and enhance the stability of the ring. This electronic effect also affects its chemical reactivity. For example, in electrophilic substitution reactions, methoxy groups can guide substituents into their adjacent and para-positions. < Br >
The acetyl group is attached to the pyridine ring. Although its carbonyl group has a certain reactivity, it interacts with the pyridine ring under normal conditions, resulting in a certain degree of stability of the molecule as a whole. For example, in a mild environment, without specific reagents and conditions, the typical reaction of carbonyl groups, such as nucleophilic addition, is also difficult to proceed spontaneously.
However, it should be noted that the stability is not absolute. When encountering special reagents such as strong oxidants, strong acids, and strong bases and severe conditions, its structure and properties will also change. For example, under the action of strong acids, the pyridine ring may undergo protonation, which in turn affects its electron cloud distribution and reactivity; strong oxidants may be able to oxidize the carbonyl group of the acetyl group, or cause oxidative damage to the pyridine ring.
Overall, 3-acetyl-2-methoxypyridine is relatively stable in conventional environments and general operating conditions, but in specific chemical environments and reagents, its stable state may be broken, showing a variety of chemical reactivity.

The synthesis method of 3-acetyl-2-methoxypyridine, although the ancient book "Tiangongkai" does not contain the synthesis of this specific substance, the method of organic synthesis today can be found.
One method is to use 2-methoxypyridine as the starting material. First, 2-methoxypyridine and acetic anhydride under the action of a suitable catalyst, such as anhydrous aluminum trichloride, at a specific temperature, about 80-100 ℃, in an organic solvent, such as dichloromethane, are acylated by Fu-g. In this reaction, the acyl group of acetic anhydride under the guidance of the catalyst attacks the specific position of 2-methoxypyridine, and is replaced by electrophilic substitution to generate 3-acetyl-2-methoxypyridine. After the reaction is completed, the pure product can be obtained by conventional separation and purification methods, such as extraction, column chromatography, etc.
Another method uses 2-hydroxypyridine as the starting material. Methoxylated first, it can react with iodomethane in an alkaline condition, such as potassium carbonate, in an acetone solvent to generate 2-methoxypyridine. Then, the target product 3-acetyl-2-methoxypyridine can be obtained by reacting with acetic anhydride and anhydrous aluminum trichloride according to the previous method. This route has a little more steps, but the raw material 2-hydroxypyridine may be easier to obtain.
Furthermore, it can be started from 2-chloropyridine. React with sodium methoxide first, and replace the chlorine atom with a methoxy group to obtain 2-methoxypyridine. Subsequent Fu-gram acylation reaction, as described above, can also produce 3-acetyl-2-methoxypyridine. All synthesis methods have their own advantages and disadvantages, and they need to be selected according to factors such as the availability of raw materials, cost, and difficulty of reaction conditions.

The price of 3-acetyl-2-methoxypyridine in the market is difficult to judge. The price of the cover is not a constant, but is made by many ends.
First, the production method is different, and the price of the materials used is different. If the materials used are rare and expensive, and the production process is complicated, the cost will be high, and the price will also be high. Second, the supply and demand of the city have a very small impact. If there are many people who want it, and the supply is small, the price will rise; conversely, the supply exceeds the demand, and the price may decline. Third, the different sellers have different prices. Various companies compete for the market, or there is a difference in pricing.
The method of Guanfu's "Tiangong Kaiwu", although the price of this medicine is not detailed, it can be deduced. The method of recreating the material in the book, the method is good, and the material is excellent, but the price is different. When it comes to the circulation of the product, the width of the market is also related to the price.
If you want to know the exact price of 3-acetyl-2-methoxypyridine today, you must check the market situation in detail. Consult the merchants of chemical materials and observe the changes in their quotations; refer to the reports of the market adjustment to clarify the trend of supply and demand. Only then can you get a near-real price, so as not to misjudge. And the market conditions are changing rapidly, and the price has also moved accordingly. It is necessary to pay attention to it often.
