2-Methyl-3-methoxypyrazine is one of the organic compounds. It has unique physical properties and is widely used in various fields such as chemicals and fragrances.
Looking at its physical properties, it is a colorless to light yellow transparent liquid under normal conditions, and it has a specific aroma. This aroma is quite unique, and it can be used as an important component in the preparation of fragrances, giving flavors a different smell. Its boiling point is about 172-174 ° C. Due to the intermolecular force, it has such a specific boiling point. This boiling point characteristic makes it suitable for separation and purification operations.
As for the melting point, it is about -18 ° C. This low-temperature melting point indicates that it solidifies in a relatively low-temperature environment. And because its density is about 1.03 g/cm ³, it is slightly denser than water. And slightly soluble in water, this solubility is due to the comprehensive action of hydrophilic and hydrophobic groups in its molecular structure. And soluble in organic solvents such as ethanol and ether, due to the principle of similar miscibility, its molecular structure is in agreement with the molecular structure of organic solvents.
In addition, the vapor pressure of 2-methyl-3-methoxypyrazine has a specific value at a specific temperature, which is related to its volatilization performance and affects the speed and degree of odor emission in different environments. Its refractive index is also a specific value, which can be used as one of the identification criteria in optical related applications or analytical testing.
These physical properties are interrelated and together determine the use and behavior of 2-methyl-3-methoxypyrazine in various fields, which is of great significance in industrial production and scientific research.

2-Methyl-3-methoxypyrazine, this substance has specific chemical properties. Its shape is colorless to light yellow liquid, with a unique aroma of nuts, roasted incense and soil. It is often used as a flavoring agent in the food and fragrance industries. Because of its unique aroma, it can add complex and attractive flavors.
Regarding physical properties, the boiling point is about 172-174 ° C, the relative density is nearly 1.03, and the refractive index is about 1.496. It has limited solubility in water, but it can be miscible with organic solvents such as ethanol and ether.
In terms of chemical properties, the presence of pyrazine rings gives it unique reactivity. Nitrogen atoms have lone pair electrons and can participate in nucleophilic reactions. Due to the substitution of methoxy group and methyl group, the distribution of electron cloud changes, which affects the reactivity and selectivity. For example, in the electrophilic substitution reaction, methoxy group is the power supply group, which increases the density of electron clouds in the adjacent and para-position, and the electrophilic reagents are more likely to attack the adjacent and para-position.
In addition, 2-methyl-3-methoxy pyrazine can undergo oxidation and reduction reactions. Under certain conditions, the pyrazine ring can be reduced, or the side chain methyl and methoxy groups can undergo oxidation reactions. Its stability is good, and it can be stored at room temperature and pressure, but when it encounters strong oxidizing agents, strong acids, and strong bases, the reaction may cause structural changes.
In conclusion, the unique chemical properties of 2-methyl-3-methoxypyrazine are of great significance in the fields of flavor preparation and food flavor improvement. In-depth understanding of its properties can provide a solid theoretical foundation for related applications.

The preparation method of 2-methyl-3-methoxypyrazine, although the ancient book "Tiangongkai" does not specify the preparation method of this specific product in detail, the current preparation method relies on the technique of chemical synthesis.
One method is to use a suitable pyrazine derivative as the starting material. First, in a suitable reaction vessel, place the pyrazine parent and add an appropriate amount of methylating agent, such as methylating agent or iodomethane. The reaction system needs to be controlled under a specific temperature and pressure, usually in a mild heating state, between about 40 and 60 degrees Celsius, and a suitable base as a catalyst, such as potassium carbonate, is required to assist the reaction. Under these conditions, the methylating reagent undergoes a substitution reaction with the pyrazine parent, and a methyl group is introduced into the pyrazine ring.
Then, to introduce a methoxy group, move the resulting methyl-containing pyrazine product to a new reaction system. Add a methoxylating reagent, such as sodium methoxide. This reaction also requires precise temperature control, about 50 to 70 degrees Celsius. In a specific organic solvent, such as N, N-dimethylformamide, the methoxy group successfully replaces the hydrogen atom at a specific position on the pyrazine ring, resulting in 2-methyl-3-methoxypyrazine.
There is another method. Starting from a specific nitrogen-containing heterocyclic compound, the pyrazine ring structure is gradually constructed through a multi-step reaction, and then methyl and methoxy groups are introduced in sequence. First, the nitrogen-containing heterocyclic compound and the carbonyl-containing compound are condensed under suitable acid and base conditions to construct the prototype of the pyrazine ring. After that, as in the above steps, methylating reagents and methoxylating reagents are used to introduce the required substituents in turn. After careful separation and purification processes, high-purity 2-methyl-3-methoxylpyrazine can be obtained. All these preparation methods rely on the delicacy of today's chemical science and engineering technology, which is not as detailed as the ancient "Tiangong Kaiwu".

2-Methyl-3-methoxypyrazine is in the market, and its price range is difficult to determine. This is due to many reasons, causing its price to change.
First, whether the purity of quality is related to the price. If the quality is high, almost perfect, and there is no disturbance, the price will be high; and if there are a little more impurities, it will be purely at a loss, and the price will drop.
Second, the demand for supply is also a major factor. If there are many people in the market, the demand is greater than the supply, and the price will rise; if there are many producers and the supply exceeds the demand, the price may fall.
Third, the system method also affects the price. Although the ancient method is familiar, it is time-consuming; new techniques or cost-saving to improve efficiency, resulting in different costs and different prices.
Fourth, the difference in origin, the price is also different. If it is shipped from a distance, the price may be higher than that produced nearby due to the cost of freight and other expenses.
Roughly speaking, the price per kilogram may be between hundreds and thousands of yuan. If you want to know the exact price, you need to consult the chemical raw material supplier, the city's broker, or check it in detail on the special trade platform to get the nearest accurate price.
