2-% methoxy-3- (isopropyl) pyridine is an organic compound. It has the following physical properties:
Viewed at room temperature and pressure, it is mostly a colorless to light yellow transparent liquid, with pure color, no obvious impurities, and a certain fluidity, like a clear spring.
Smell it, emit a special organic smell, this smell is not pungent and intolerable, but it is quite unique. Those who are familiar with organic chemicals can recognize its unique smell, just like the unique fragrance in the garden of chemistry. < Br > Measure its boiling point, which is about a specific temperature range. Due to the intermolecular forces and structural characteristics, a certain amount of thermal energy is required to convert it from a liquid state to a gaseous state, just like it has been tempered by a specific heat before it can be sublimated.
Measure its melting point, and it is in a certain low temperature range. Under the low temperature environment, the molecular movement slows down, approaches each other, and arranges in an orderly manner into a solid state, just like everything dormant in winter, waiting for the awakening of spring.
In terms of its solubility, it shows good solubility in common organic solvents such as ethanol and ether, and can interact with solvent molecules, disperse uniformly, as if it is integrated into a new environment and coexist harmoniously; in water, its solubility is limited, because its molecular structure polarity is quite different from that of water, just like oil and water, it is difficult to
Its density is also a specific value, which may be different from that of water. When placed in water, it may float or sink, depending on the density difference, reflecting the characteristics of molecular packing compactness.
These physical properties of 2-% methoxy-3- (isopropyl) pyridine are like its unique "identity mark". In the fields of organic synthesis, pharmaceutical research and development, researchers can use this to separate, purify, identify and other operations. In the stage of chemistry, it can be precisely positioned and play a unique role.

The chemical properties of 2-% methoxy-3- (isopropyl) pyridine compounds are quite stable. In its structure, the methoxy group is connected to the pyridine ring. In the methoxy group, the oxygen atom forms a p-π conjugation effect with the pyridine ring by virtue of its lone pair electrons, which changes the electron cloud density distribution on the pyridine ring and enhances the stability of the part of the structure.
Furthermore, the isopropyl group is connected to the pyridine ring, which has a electron-inducing effect, which can provide electrons for the pyridine ring, further stabilizing the electronic structure of the pyridine ring. Spatially, the presence of isopropyl, due to its large steric resistance, can produce a certain shielding effect on the periphery of the pyridine ring, hindering the attack of external reagents on the pyridine ring, and improving the stability of the compound from the perspective of steric resistance.
At the same time, the pyridine ring itself has aromaticity, which is composed of a closed conjugate system and satisfies the 4n + 2 electron rule (n is an integer). This aromaticity imparts high stability to the pyridine ring, making the entire 2-% methoxy-3- (isopropyl) pyridine compound less prone to reactions such as ring opening that destroy its stable structure. In summary, the interaction of many factors results in the chemical stability of 2-% methoxy-3- (isopropyl) pyridine under normal conditions.

To prepare 2-methyl-3- (isopropyl) pentane, you can follow the following ancient methods.
First take a suitable halogenated hydrocarbon, such as 2-chloro-3-isopropylpentane, which can be obtained by halogenation of the corresponding alcohol. When selecting an alcohol, when 2-pentanol is used as the base, methyl is introduced at the 2nd position, and isopropyl is introduced at the 3rd position. The preparation of this alcohol requires delicate design.
Using valeraldehyde as the starting material, it is first reacted with methyl Grignard reagents (such as methyl magnesium bromide), and methyl can be introduced at the α-position of the aldehyde group to generate 2-methyl-1-pentanol. Then the alcohol is oxidized to obtain 2-methylpentanone. Then 2-methylpentanone is reacted with isopropyl Grignard reagents (such as isopropyl magnesium bromide), and isopropyl can be introduced at the α-position of the carbonyl group. After hydrolysis, 2-methyl-3-isopropyl-3-pentanol is obtained.
After obtaining 2-chloro-3-isopropylpentane, it can be reacted with metals such as zinc or magnesium in a suitable organic solvent to form an organometallic compound. If the organozinc compound is formed, it is then reacted with a halogenated alkane (such as iodomethane), and the alkyl part of the halogenated alkane is connected to the hydrocarbon group in the organometallic compound to obtain 2-methyl-3- (isopropyl) pentane.
It can also be prepared by addition reaction of olefins. Suitable olefins such as 2-methyl-3-isopropyl-2-pentene are synthesized first. The olefin can be obtained from the above-mentioned 2-methyl-3-isopropyl-3-pentanol by dehydration reaction. The olefin is added to hydrogen in the presence of appropriate catalysts (such as palladium, platinum, etc.), and the hydrogen atoms in the hydrogen molecule are added to the carbon atoms at both ends of the double bond of the olefin to obtain 2-methyl-3- (isopropyl) pentane.
The method of preparing 2-methyl-3- (isopropyl) pentane requires the selection of the superior one according to the actual situation.

In today's market, the price of 2-methoxy-3- (isopropyl) pyridine is about between twenty-five and thirty-five gold per catty. This price varies from time to time and from quality to quality. If the quality is pure and fresh, the price may be slightly higher; if the quality is flawed, the price is slightly lower.
The fluctuation of its price is also affected by various reasons. First, the price of raw materials is the main factor. If the price of the raw materials for making this thing rises, the price of the finished product will also rise; if the price of raw materials falls, the price of the finished product may fall accordingly. Second, the supply and demand of the market are also heavy. If there are many people who want it, and there are few suppliers, the price will rise; if the supply exceeds the demand, the price will be reduced. Third, the ingenuity of the craftsmanship is also involved. If the craftsmanship is high, the yield is high, and the cost is reduced, the price can be cheap; if the craftsmanship is coarse, the yield is low, and the cost is high, the price cannot be reduced.
Therefore, if you want to know the real-time price of this thing, you should consult the people in the city or the books of merchants to get a definite number. And you must constantly observe the changes in the city and understand the movements of various reasons, so that you can predict the trend of its price, and find an opportunity in business.
