2-Ethoxy-3- (isopropyl) pyrazine, this is an organic compound. Its physical properties are quite characteristic, and it is closely related to chemical synthesis, fragrance application and other fields.
Looking at its properties, under room temperature and pressure, it is mostly a colorless to light yellow transparent liquid. Its color is elegant, like the first dew of morning light, pure and soft. Its smell is unique, exudes a fresh and baking aroma, just like the tempting fragrance that escapes when baking grains, leisurely, can provoke people's olfactory perception.
Talking about the melting point, the melting point is extremely low, and it is difficult to condense into a solid state at room temperature, just like smart water, which keeps flowing at all times. The boiling point is about a certain temperature range, and this temperature range allows it to realize the conversion of liquid and gaseous states under specific conditions.
In terms of solubility, in organic solvents, such as ethanol, ether, etc., its solubility is quite good, just like a fish getting water, it can blend with it. However, in water, the solubility is relatively limited, and it is difficult for the two to completely dissolve each other, as if there is an invisible barrier.
Compared with water, its density is relatively light, like a feather floating on the water surface, and it can take on its own form in the upper layer.
Its vapor pressure also has a certain value at a specific temperature, and this value reflects the difficulty of its volatilization. In a suitable environment, it can evaporate slowly, dispersing its own unique atmosphere in the surrounding space. The physical properties of 2-ethoxy-3- (isopropyl) pyrazine not only determine its behavior in chemical reactions, but also play a key role in the fragrance industry. Due to its unique odor, it is often used as an important ingredient in the preparation of fragrances, adding a unique aroma to various products.

2-Ethoxy-3- (isopropyl) pyrazine, this is an organic compound. Looking at its structure, the pyrazine ring is the group, and the ethoxy group and the isopropyl group are respectively connected to the specific position of the pyrazine ring.
In terms of its physical properties, under normal temperature and pressure, or in a liquid state, it has a certain volatility and has a special odor. Its boiling point, melting point and other properties are the characteristics of its physical properties. Due to the presence of ethoxy and isopropyl groups in the molecular structure, the intermolecular forces have their own unique characteristics, which in turn affect its melting boiling point.
As for the chemical properties, the pyrazine ring has certain aromatic properties and can undergo electrophilic substitution reactions. The nitrogen atom on the ring has a lone pair of electrons, which can participate in coordination chemistry-related reactions and form complexes with metal ions. The oxygen atom in the ethoxy group has a partial negative charge and can participate in nucleophilic reactions; isopropyl is the power supply group, which has an effect on the electron cloud density distribution of pyrazine rings, or changes its reactivity and selectivity.
In addition, this compound can participate in various organic synthesis reactions due to its functional groups, such as ether bond cleavage reaction, alkylation reaction, etc. In the field of organic synthesis, it can be used as an intermediate for the preparation of more complex organic compounds, which may have potential applications in many fields such as medicinal chemistry and materials science.

The synthesis of 2-ethoxy-3- (isopropyl) pyrazine is an important matter in the field of organic synthetic chemistry. The synthesis of this compound often involves multiple methods, each with its own advantages and disadvantages, and needs to be carefully selected according to the specific situation.
First, it can be started from pyrazine derivatives. First, a pyrazine precursor with a specific substituent is prepared. For example, a suitable halogenated pyrazine is selected and reacted with sodium ethanol to form an ethoxy substituent. After that, it is reacted with an isopropylation reagent, such as an isopropyl halide, under a suitable base catalyst to achieve the introduction of isopropyl. In this process, it is crucial to precisely control the reaction conditions, such as temperature, reaction time, and the proportion of reactants, which all affect the yield and purity of the product.
Second, the strategy of constructing pyrazine rings can be adopted. Nitrogen-containing and carbonyl-containing compounds are used as starting materials to form pyrazine rings through cyclization, and ethoxy and isopropyl are introduced at the same time. For example, the use of 1,2-dicarbonyl compounds with ethoxylamine and isopropylamine undergoes condensation cyclization under acidic or basic catalysis. This path requires careful regulation of reaction conditions to ensure the smooth progress of the reaction and avoid side reactions such as excessive condensation or isomerization.
Third, the coupling reaction catalyzed by transition metals is also an optional method. Halogenated pyrazine is used as a substrate, and it is catalyzed by transition metals such as palladium and nickel to couple with ethoxylation reagents and isopropylation reagents respectively. The key to this method is to select high-efficiency catalysts and ligands to improve the reactivity and selectivity, and the reaction system needs to be strictly anhydrous and oxygen-free to prevent metal catalysts from deactivating.
When synthesizing 2-ethoxy-3- (isopropyl) pyrazine, a suitable synthesis method should be carefully selected according to factors such as raw material availability, cost, reaction complexity and product purity requirements in order to achieve the purpose of efficient synthesis.

I don't know what the price range of "2 - ethoxy - 3 - (propan - 2 - yl) pyrazine" is on the market. This is a fine chemical, and its price is determined by many factors.
First, the purity has a great impact. If the purity is extremely high, it is almost used for high-purity products in high-end scientific research and pharmaceutical fields, and the price will be high. Gai because of its complicated purification process, which consumes a lot of manpower, material resources and time, requires precision instruments and exquisite technology to reach high purity standards, so the price may be tens or even hundreds of yuan per gram.
Second, market supply and demand have a significant impact. If the demand for this product is strong, such as a surge in demand in the field of specific fragrances and pharmaceutical research and development, and the supply is limited, the price will rise. On the contrary, if the market demand is low, the production supply is sufficient, and the price may fall.
Third, the scale of production also has an impact. In large-scale production, due to the scale effect, the unit production cost may drop, and the price may be relatively close to the people. Small-scale production, the cost is difficult to drop, and the price may be high.
Fourth, the source and channel are different, and the price is also different. Imported products may have higher prices due to tariffs, transportation and other costs; those produced locally and with proper cost control may have competitive prices.
In short, to determine the price range, check the chemical product trading platform, consult suppliers, or conduct research at relevant industry exhibitions to obtain more accurate price information.
