2% 2C3-dihydroxy-6-methoxypyridine is a crucial compound in the field of organic synthesis, and its synthesis methods are quite diverse. The following will be described in detail:
First, 2-methyl-3,6-dihydroxypyridine is used as the starting material. First, 2-methyl-3,6-dihydroxypyridine is methylated. Usually, dimethyl sulfate or iodomethane can be selected as the methylation reagent. In the presence of alkaline environment, such as potassium carbonate or sodium hydroxide, the reaction is carried out in a suitable organic solvent, such as acetone or N, N-dimethylformamide. In this way, the target product 2,3-dihydroxy-6-methoxypyridine can be obtained. The raw materials for this route are relatively easy to obtain and the reaction conditions are relatively mild, which is a commonly used synthesis strategy.
Second, start from 2,3-dichloropyridine. First, 2,3-dichloropyridine reacts with sodium methoxide in a methanol solution, and the chlorine atom is replaced by a methoxy group to form 2-methoxy-3-chloropyridine. Subsequently, through the hydroxylation reaction, with a suitable nucleophilic agent, such as sodium hydroxide aqueous solution, at a specific temperature and pressure, the remaining chlorine atoms are replaced by hydroxyl groups to obtain 2,3-dihydroxy-6-methoxypyridine. This route has a little more steps, but the reaction selectivity of each step is good and the yield is quite good.
Third, pyridine-2,3,6-triphenol is used as the starting material. Pyridine-2,3,6-triphenol reacts with dimethyl sulfate under basic conditions to selectively methylate the 6-phenol hydroxyl group, and then generates the target product 2,3-dihydroxy-6-methoxypyridine. The steps of this method are short, but the preparation of raw material pyridine-2,3,6-trisphenol may be difficult.
Synthesis of 2,3-dihydroxy-6-methoxypyridine has its own advantages and disadvantages. In practical application, it is necessary to carefully select the appropriate synthesis path according to many factors such as raw material availability, cost, reaction conditions and product purity.

2% 2C3-dihydroxy-6-methoxybenzaldehyde, this is an organic compound. Its physical properties are quite unique.
Looking at its appearance, it is often in the state of white to light yellow crystalline powder, which shines in the sun, like broken stars falling on the world. Its smell is quiet and slightly fragrant, just like the faint floral fragrance from the spring breeze, not pungent and pleasant.
When it comes to solubility, this compound is slightly soluble in water, like a shy dancer, dancing lightly in water, but maintaining its own independence. However, it has good solubility in organic solvents, such as ethanol, ether, etc., just like fish entering water, it can blend with it. < Br >
Melting point is also one of its important physical properties. At a certain temperature range, when the outside temperature rises to this point, it slowly converts from solid to liquid, just like melting ice and snow, opening a new form journey.
Furthermore, its stability is good under normal conditions, just like a calm person, able to resist the intrusion of common environmental factors. However, under extreme conditions such as high temperature, strong acid, and strong alkali, its structure may change, just like a building may shake in a storm.
In terms of density, it has its own specific value, which is invisible but real, and determines its ups and downs in different media. It is also an important part of its physical characteristics.
In summary, the many physical properties of 2% 2C3-dihydroxy-6-methoxybenzaldehyde together paint a unique chemical "portrait", which makes it have a unique position and application value in the field of chemistry.

Today there is a question, what is the price of 2,3-dihydroxy-6-methoxybenzaldehyde in the market? This is a key material in the field of fine chemicals, and its price is determined by many factors.
The first to bear the brunt is the simplicity of the preparation process. If the preparation requires multiple exquisite processes, the reagents used are rare and the reaction conditions are harsh. If precise temperature control and the environment of eliminating oxygen and water are required, the cost will rise and the price will be high. For example, if a specific natural product is used as the starting material and is transformed into a complex chemical in multiple steps, the price will be high because the raw materials are rare and the operation is complicated.
Furthermore, the state of market supply and demand is also an important reason. If this aldehyde is in high demand in the fields of pharmaceutical synthesis, material research and development, and the supply is limited, the price will rise. Suppose the demand for a new type of anti-cancer drug research and development surges, but the production capacity is difficult to expand for a while, and its price will rise with demand.
In addition, quality specifications also affect its price. Products with high purity and very few impurities are suitable for high-end scientific research and precision pharmaceutical production, and the price is naturally higher than that of ordinary specifications. For example, the synthesis of special materials in the manufacture of power supply chips requires extremely high purity, and the price is far higher than that of general industrial-grade products.
According to the current market situation, the price of ordinary industrial-grade 2,3-dihydroxy-6-methoxybenzaldehyde may be several hundred yuan per kilogram. However, the price of pharmaceutical grade and high purity can reach tens of yuan or even higher per gram. However, the market situation is unpredictable, and the price will also rise or fall. To know the exact price, you need to consult the chemical raw material supplier in detail, subject to the real-time market.

2% 2C3-dihydroxy-6-methoxybenzophenone, this material is delicate and needs to be stored with caution. Its fear of light is like a mouse avoiding a cat. Under light, the molecules are easy to move, and the structure gradually shifts, causing it to lose its effectiveness. Therefore, it needs to be hidden in the dark and not see the sun.
And its nature is cold and hot, the temperature is high and boiling, the molecules are rushing disorderly, the quality is bad and useless; if the temperature is low, it will coagulate, and the internal structure will be stiff, which will also damage its properties. The best storage temperature is suitable for a cool place, neither cold nor hot, just like the temperature of a spring day, between 20 and 25 degrees Celsius, to keep its stability.
Furthermore, moisture is like a thief, which can also harm it. Water vapor adheres to it, gradually erodes its substance, and makes it mildew and rot. Therefore, when hiding, it needs to be placed in a dry place, such as a pottery urn or a porcelain bottle, and sealed with wax to prevent moisture from invading, so that it can last for a long time without losing its effectiveness.
