2-Methoxy-3 (5/6) -methylpyrazine, this is an organic compound with unique physical properties and applications in many fields.
Looking at its properties, it is liquid at room temperature, colorless to light yellow, with a clear and transparent appearance, pure like jade dew, no obvious visible impurities, and a warm luster.
When it comes to odor, it emits a strong nutty and baking aroma, just like nuts baked on fire, giving off an attractive smell. It is widely used in the field of food flavors and can add unique flavors.
Its boiling point, after rigorous determination, is about 190-200 ° C. At this temperature, the compound changes from liquid to gaseous state, just like ice melts into water, and the state changes. The boiling point is affected by intermolecular forces. The compound forms a specific force due to its molecular structure, causing the boiling point to be in this range.
In terms of melting point, it is about -20 ° C to -10 ° C. When the temperature drops to the melting point, the liquid state becomes solid, such as river water freezing in winter. The melting point is also determined by molecular structure and interaction, and the molecular arrangement and force reach a balance, presenting this melting point range.
In terms of solubility, it has good solubility in organic solvents such as ethanol and ether, just like salt dissolves in water, and can disperse uniformly. Due to the affinity between the compound and the organic solvent molecules, it follows the principle of similar miscibility. However, its solubility in water is limited, and it is difficult to dissolve in water due to its large difference in molecular polarity and weak interaction with water.
The density is about 1.05 - 1.15 g/cm ³, which is slightly heavier than water. Dropping it on the water surface will sink like a stone into water, which is determined by the density characteristics. The density is determined by the molecular mass and the compactness of the compound structure, and the density of the specific structure and mass is in this range.

2-Methoxy-3 (5/6) -methylpyrazine is an organic compound with unique chemical properties. In terms of physical properties, it is mostly liquid at room temperature. Due to its molecular structure containing polar group methoxy and pyrazine ring, it is slightly soluble in water and miscible with some organic solvents, such as ethanol, ether, etc.
From the perspective of chemical properties, the pyrazine ring gives it a certain aromaticity and is relatively stable. Methoxy is the power supply group, which can increase the electron cloud density of the pyrazine ring, which in turn affects its reactivity. This compound can participate in the electrophilic substitution reaction, and the methoxy ortho-and para-sites are more susceptible to the attack of electrophilic reagents, because it can increase the electron cloud density of the ortho-and para-sites of the benzene ring to a greater extent than the meta-sites.
At the same time, the methyl group is attached to the pyrazine ring, which also affects its properties. Methyl is a power supply group, which affects the electron cloud distribution of the pyrazine ring, or changes its reaction selectivity. In addition, 2-methoxy-3 (5/6) -methylpyrazine may also participate in some reactions involving nitrogen atoms. The nitrogen atom in the pyrazine ring has a lone pair electron, which can be used as an electron donor to form complexes with metal ions, etc., or participate in some nucleophilic reactions.
Its chemical properties make it widely used in the fields of fragrances, medicine, pesticides, etc. In the field of fragrances, its unique smell can be used as a flavor preparation ingredient; in the field of medicine, its chemical structure may be a lead compound, which has been modified to develop specific biologically active drugs; in the field of pesticides, it can be used as a synthetic new pesticide raw material, and its chemical properties can play the functions of insecticide and sterilization.

The preparation method of 2-methoxy-3 (5/6) -methylpyrazine, although not directly described in the ancient book "Tiangong Kaiwu", can now be prepared by chemical synthesis.
First, the corresponding pyrazine derivative can be started. First take a suitable pyrazine parent, if it has a modifiable functional group, such as a halogen atom or a hydroxyl group. If it contains a halogen atom, a nucleophilic substitution reaction can be used to replace it with a methoxy negative ion, which can be provided by reagents such as sodium methoxide. During the reaction, halogenated pyrazine and sodium methoxide are stirred in a suitable solvent, such as dimethylformamide (DMF) or dimethyl sulfoxide (DMSO), at a suitable temperature. The temperature control is very important. If the temperature is too low, the reaction will be slow, and if it is too high or side reactions will occur.
Second, if the starting material is a pyrazine derivative containing hydroxyl groups, the hydroxyl groups can be converted into easy-to-leave groups, such as p-toluenesulfonate ester groups, and then reacted with methoxy reagents, methoxy substitution products can also be obtained.
As for the introduction of methyl groups, if the initial pyrazine ring has no methyl groups, the alkylation reaction can be used. React with the pyrazine derivative with a suitable methylating agent, such as iodomethane, in the presence of a base. The base can be selected from potassium carbonate, etc., and the reaction is carried out in a solvent to promote the substitution of methyl to the appropriate position of the pyrazine ring. During operation, attention should be paid to the precise control of the reaction conditions to increase the yield and purity of the target product.
