2-%28butan-2-yl%29-3-methoxypyrazine is 2- (sec-butyl) -3 -methoxypyrazine, the physical properties of this substance, let me talk about them one by one.
Looking at its properties, under room temperature and pressure, it is mostly colorless to light yellow liquid, just like clear water, but it contains a unique chemical mystery. Its smell is particularly special, with a strong mixed aroma of nuts, soil and baking. Smell it, just like being in a nut bakery, the fragrance of soil and baking is intertwined, which is fascinating.
Talking about the boiling point, it is between 198 and 200 degrees Celsius. At this temperature, the balance of intermolecular forces is broken, and the liquid 2- (sec-butyl) -3-methoxypyrazine gradually turns into a gaseous state. The melting point information is relatively difficult to find exact data, or because under common conditions, it is rarely involved in the process of transforming from solid to liquid.
In terms of density, it is about 1.01 g/cm ³, which is similar to the density of water. When placed in water, it may have a slight floating state, which seems to dance with water, showing its unique physical properties. As for solubility, it can be dissolved in organic solvents such as alcohols and ethers, just like fish entering water, it fuses seamlessly, but it is difficult to dissolve in water. It forms its own body in water and exhibits hydrophobicity.
In addition, its vapor pressure and volatility are also important physical properties. Because of its certain volatility, it can slowly diffuse its unique odor in the air. Although the value of vapor pressure is difficult to describe accurately, it can be inferred that at room temperature, the tendency of molecular escape liquid phase is moderate, neither too active nor too stable. The above physical properties of 2 - (sec-butyl) - 3 - methoxypyrazine are related to each other, which together depict the unique picture of this compound in the physical world and lay the foundation for its application in the fields of flavors and food.

2-%28butan-2-yl%29-3-methoxypyrazine is 2 - (sec-butyl) - 3 - methoxypyrazine, which has special chemical properties. It is colorless to light yellow liquid and stable at room temperature and pressure, but it is at risk of burning in case of open flame and hot topic.
In terms of physical properties, it has a smell similar to nuts, soil and roasting, and is widely used in the field of fragrances. The boiling point is about 190 - 192 ° C, the density is nearly 0.99 g/cm ³, slightly soluble in water, and can be miscible with organic solvents such as ethanol and ether.
In terms of chemical properties, because it contains pyrazine ring with methoxy group and sec-butyl group, pyrazine ring is aromatic and can undergo electrophilic substitution reactions, such as halogenation, nitrification, etc. The reaction check point is mostly at the higher electron cloud density on the ring. Methoxy group is the power supply group, which will increase the electron cloud density of pyrazine ring and improve the electrophilic substitution activity; sec-butyl group has a greater impact on the molecular spatial structure and physical properties.
It can also participate in some organic synthesis reactions. For example, under certain conditions, methoxy group can be replaced by other groups to prepare pyrazine compounds with more complex structures. It is an important intermediate in organic synthesis chemistry.
2- (sec-butyl) -3 -methoxypyrazine is of great significance in the fields of fragrance and organic synthesis due to its unique physical and chemical properties.

To prepare 2 - (butyl-2-yl) -3 -methoxypyrazine, there are many methods, which can be found from the classical organic synthesis.
First, using pyrazine as the base, select a suitable halobutane, and under the catalysis of a base, perform a nucleophilic substitution reaction. First, the pyrazine interacts with the base, so that the nitrogen atom is negatively charged, and then meets the halobutane, the halogen atom leaves, and the butyl is then connected to the pyrazine. Next, another methoxylation reagent is taken, such as the methoxy negative ion formed by iodomethane and sodium alcohol, which reacts with the pyrazine that has been connected to butyl, and the methoxy group replaces the hydrogen atom, and finally obtains the target product. This process requires detailed control of the reaction temperature, time and the ratio of reagents to increase the purity and yield of the product.
Second, it can be obtained by cyclization from raw materials containing corresponding substituents. If a chain compound containing butyl and methoxy is selected, the active groups at both ends of it can interact under suitable conditions to form a pyrazine ring. In this case, it is necessary to find a suitable catalyst and reaction environment, or use a metal catalyst to catalyze the formation of carbon-heteroatomic bonds, and also pay attention to the stability and transformation of the intermediate of the reaction to ensure that the reaction proceeds along the expected path and reduce the generation of side reactions.
Or, refer to the synthesis strategies of similar compounds of predecessors to improve. Because the beauty of organic synthesis lies in flexibility, many reaction mechanisms and conditions can be learned and optimized. However, no matter what method, it needs to be repeatedly verified by experiments, detailed analysis of the structure and purity of the product, and continuous improvement of the synthesis method, so as to achieve the purpose of efficient and pure preparation of 2- (butyl-2-yl) -3-methoxypyrazine.

I don't know what the price range of 2- (butyl-2-yl) -3-methoxypyrazine is in the market. However, if you want to know the price of this product, you should follow various channels.
