To prepare 2-hydroxy-3-methoxy-6- (triethylmethyl) pyridine, there are many methods for its synthesis, which are described in detail today.
First, the corresponding pyridine derivative can be used as the starting material. First, a specific position on the pyridine ring is halogenated to introduce a halogen atom, such as bromine or chlorine. This step requires selecting a suitable halogenation reagent and reaction conditions, or under the action of light and catalyst, so that the halogen atom precisely falls on the place to be modified. Then, a nucleophilic substitution reaction is used to replace the halogen atom with a methoxy negative ion to achieve the construction of 3-methoxy. The methoxy source can select reagents such as sodium methoxide and put them in suitable solvents, such as polar aprotic solvents, to make the reaction occur smoothly. As for the introduction of 2-hydroxyl groups, the subsequent hydrolysis reaction can be carried out by using a specific base or acid as a catalyst, under heating conditions, to promote the hydrolysis of specific ester groups or ether groups to generate hydroxyl groups. For the access of 6 - (triethyl methyl), organometallic reagents, such as Grignard reagents, can be used to undergo nucleophilic addition reaction with the activated check point on the pyridine ring. After careful regulation of the reaction temperature, time and reagent ratio, the target product can be obtained.
Second, the construction of the pyridine ring can also be started. Using suitable nitrogenous compounds and carbonyl compounds as raw materials, the prototype of the pyridine ring is first constructed through multi-step condensation reaction. For example, by using the Hantzsch pyridine synthesis method, β-ketone ester, aldehyde and ammonia or their derivatives are used as reactants. In the presence of acidic catalysts, pyridine derivatives are cyclized. Then, for each substituent on the pyridine ring, 2-hydroxy, 3-methoxy and 6- (triethyl) are introduced in sequence according to the above-mentioned similar substitutions, hydrolysis, and addition reactions.
Third, the coupling reaction catalyzed by transition metals can also be used. First, pyridine intermediates with suitable substituents and reactive check points are prepared, and then transition metal catalysts such as palladium and nickel are used to catalyze the coupling reaction with organic halides or borates containing triethyl groups to achieve 6- (triethyl) connection. At the same time, at other check points, hydroxylation, methoxylation and other reactions are used as needed to form the target 2-hydroxyl-3-methoxy-6- (triethyl) pyridine. Each method has its advantages and disadvantages. Experimenters need to carefully choose the appropriate synthesis path according to the actual situation, such as the availability of raw materials, the difficulty of reaction, and the purity of the product.

2-% nitrile-3-furyl-6- (triethylamino) pyridine is a common compound in organic synthesis. Its physical properties are as follows:
Appearance, under room temperature and pressure, this compound is mostly white to light yellow crystalline powder, with fine texture. Viewed in sunlight, it can be seen that the fine crystal luster is flickering, just like the scattered stars.
The melting point is very critical, about [X] ° C. Under this temperature condition, the compound changes from solid state to liquid state. In specific synthesis steps and separation and purification processes, the characteristics of the melting point can be used for identification and purification.
The boiling point is also important, about [X] ° C. When operations such as distillation are involved to separate the compound or remove impurities, the boiling point characteristic is a key parameter. In terms of solubility, this compound exhibits good solubility in organic solvents such as dichloromethane, N, N-dimethylformamide (DMF), etc. In dichloromethane, it can quickly dissolve to form a clear and transparent solution, like ice and snow melting in a spring stream; in DMF, it can also be uniformly dispersed to provide a homogeneous environment for organic reactions. However, its solubility in water is poor. When added to water, it is mostly suspended with tiny particles, making it difficult to form a uniform solution, just like sand and gravel in clean water. In terms of density, it is about [X] g/cm ³. Although invisible, it plays an important role in the mixing of substances and the calculation of the density of the reaction system, affecting the interaction and stratification between substances.
In addition, the compound has a certain odor, not a pungent and unpleasant smell, but a slightly special organic smell, which seems to have a faint chemical synthesis charm. However, the smell is weak and cannot be obtained without close sniffing.

During storage and transportation of 2-% hydroxyl-3-quinyl-6- (triethyl) pyridine, the following matters must be paid attention to:
First, this compound may have potential impact on the environment and must not be disposed of at will. When storing, it should be placed away from water sources, rivers and soil to prevent its leakage and environmental pollution. During transportation, it should also be ensured that the packaging is tight to prevent leakage and outflow during transportation.
Second, this substance may have certain chemical activity, and the temperature and humidity requirements of its storage environment are quite strict. It should be stored in a cool, dry and well-ventilated place, and the temperature should be controlled within a specific range to prevent its chemical properties from changing due to excessive temperature, and to avoid moisture deterioration due to excessive humidity.
Third, because of its chemical structure characteristics, or react with many substances. When storing, it should be separated from oxidants, reducing agents, acids, alkalis and other substances, and must not be mixed to prevent dangerous chemical reactions.

Storage places and transportation vehicles should also be equipped with corresponding emergency treatment equipment and materials, so that they can respond quickly in the event of an accident and reduce hazards.

There are now 2-hydroxy- 3-methoxy-6- (triethylmethyl) pyridine, want to know its market price range. According to Guanfu's "Tiangong Kaiwu", although the price of this product is not as high as that of this product, it can be deduced according to common sense.
The price of everything is related to many ends. First, the price of raw materials. If the raw materials of this compound are easy to obtain and abundant, the cost may be low, and the price will follow. On the contrary, if the raw materials are rare and difficult to collect, the price must be high. Second, the preparation is simple and simple. If the synthesis method is simple, the process is small, and the time-consuming is short, the cost of production can be reduced, and the price can be close to the people; if the preparation technique is complicated, requires exquisite equipment, superb skills, and takes a long time, the price will be high. Third, the amount of demand. If in the market, everyone is competing, and the supply is in short supply, the price will rise; if the demand is small, and the supply exceeds the demand, the price will fall.
Looking at the current market, the price of chemical products varies depending on quality and purity. If this 2-hydroxy- 3-methoxy-6- (triethylmethyl) pyridine has high purity and excellent quality, and is used in key fields, such as pharmaceutical research and development, high-end chemical industry, etc., its price should be high. The price per gram, or ranging from tens to hundreds of yuan. If the purity is slightly inferior, it is only used for general industrial purposes, and the price may drop to a few to several tens of yuan per gram.
However, the market is fickle, and the price also moves with the trend. Sometimes the supply of raw materials changes suddenly, and sometimes the demand suddenly increases and decreases, all of which can lead to fluctuations in the price. Therefore, if you want to know its accurate price, you should carefully observe the market conditions and consult the merchants and experts in the industry.
