2-Hydroxy-6-methoxypyridine is one of the organic compounds. Its physical properties are unique and of great significance in chemical research and industrial production.
Looking at its properties, at room temperature, 2-hydroxy-6-methoxypyridine is often white to light yellow crystalline powder, which is easy to store and use. Its odor is light and has no strong pungent smell. When operating, it can protect the operator from strong odors.
When it comes to melting point, it is about 140-144 ° C. The melting point is established, and according to this characteristic, in chemical experiments and industrial production, the purification and separation of the compound can be achieved by precisely controlling the temperature, ensuring the purity and quality of the product.
Furthermore, its solubility is also a key property. 2-Hydroxy-6-methoxypyridine is slightly soluble in water, and this property is derived from the interaction between hydroxyl and methoxy groups in its molecular structure. However, it exhibits good solubility in organic solvents such as ethanol and acetone. This property allows for the selection of suitable organic solvents in organic synthesis reactions to build a reaction environment and promote the smooth progress of the reaction.
In addition, the stability of the compound cannot be ignored. Under normal temperature and environmental conditions, 2-hydroxy-6-methoxypyridine can maintain a relatively stable state. When exposed to extreme chemical environments such as strong acids and bases, its structure may change, triggering chemical reactions and generating new substances. Therefore, when storing and using, it is necessary to properly avoid such extreme conditions to prevent its deterioration.
The physical properties of 2-hydroxy-6-methoxypyridine, such as properties, melting point, solubility and stability, are interrelated and affect its application in the chemical field, providing an important foundation for organic synthesis, drug development and many other aspects.

2-Hydroxy-6-methoxypyridine, this is an organic compound with unique chemical properties. Its appearance is often white to light yellow crystalline powder, which has attracted much attention in scientific research and chemical industry.
In terms of its acidity and alkalinity, it is alkaline and acidic due to the nitrogen atom and hydroxyl group of the pyridine ring. Hydroxyl hydrogen can be dissociated and is acidic under appropriate conditions; pyridine ring nitrogen atom has lone pair electrons, can accept protons, and is alkaline. However, its acid-base properties are weaker than common strong acids and bases.
In terms of solubility, the substance has limited solubility in water, but it can be soluble in some organic solvents, such as ethanol and dichloromethane. This property is due to the fact that there are both polar groups (hydroxyl and methoxy) and non-polar pyridine rings in its molecular structure, resulting in different solubility in different solvents.
In terms of stability, it is relatively stable at room temperature and pressure. However, in case of strong oxidants, strong acids, strong bases, etc., or chemical reactions may occur. At high temperatures, decomposition and other changes may also occur.
The reactivity of 2-hydroxy-6-methoxypyridine is considerable. Hydroxyl groups can participate in esterification, etherification and other reactions. The electrophilic substitution reaction can occur on the pyridine ring. Due to the electron-withdrawing effect of nitrogen atoms, the electron cloud density of the pyridine ring is reduced. The electrophilic substitution reaction mainly occurs at the β-position of the pyridine ring (relative to the nitrogen atom). Methoxy group is the power supply group, which has an impact on the electron cloud distribution of the pyridine ring, and can affect the reactivity and selectivity to a certain extent.
In addition, this compound can be used as an intermediate in organic synthesis to prepare a variety of fine chemicals such as drugs, pesticides, and dyes. In the field of organic synthesis, with its unique chemical properties, it provides the possibility to construct complex organic molecular structures, and plays an important role in modern chemical industry and scientific research.

To prepare 2-hydroxy-6-methoxypyridine, there are various methods. One common method is to take 2,6-dimethoxypyridine as the starting material and obtain it by hydrolysis. Among them, strong acids such as sulfuric acid or hydrochloric acid are used as catalysts, and under heating conditions, the methoxy group of 2,6-dimethoxypyridine is hydrolyzed and translocated to hydroxyl groups. However, this process needs to control the reaction conditions to prevent excessive hydrolysis from causing impure products.
Furthermore, 2-chloro-6-methoxypyridine can be prepared by nucleophilic substitution. Using the alkaline solution of sodium hydroxide or potassium hydroxide as the reaction medium, the chlorine atom in 2-chloro-6-methoxy pyridine is active and easy to be replaced by hydroxyl nucleophilic, and then 2-hydroxy-6-methoxy pyridine is obtained. This way needs to pay attention to the reaction temperature and time to avoid side reactions.
And 6-methoxy-2-pyridinone is used as the raw material. After methylation reaction, suitable methylation reagents are selected, such as iodomethane or dimethyl sulfate. In an alkaline environment, the hydroxyl oxygen atom of pyridinone attacks the methylation reagent nucleophilically, forming a methoxy group and obtaining the target product. When operating, the type and dosage of the base must be carefully selected to ensure a smooth reaction.
In addition, organometallic reagents can also be used to participate in the reaction. For example, a suitable halogenated pyridine derivative can be reacted with an organomagnesium reagent (Grignard reagent) or an organolithium reagent, and then hydrolyzed and other subsequent steps can obtain 2-hydroxy-6-methoxypyridine. However, such methods have strict requirements on the reaction environment, must be anhydrous and oxygen-free, and have high activity of organic metal reagents, so the operation should be cautious.

2-Hydroxy-6-methoxypyridine is an organic compound, which is widely used in the chemical industry, medicine and other fields. However, its market price range is difficult to give accurately.
Because of the market price, it is often affected by many factors. First, the fluctuation of raw material prices has a huge impact on its cost. If the price of raw materials for synthesizing this compound rises or falls, the price of the product will also rise and fall. Second, the market supply and demand relationship is a key factor. If there is strong demand for this product in many industries and the supply is limited, the price will rise; conversely, if the demand is low and the supply is sufficient, the price will fall. Third, the production process and technical level are also affected. Advanced and efficient production processes can reduce costs and make prices more competitive; if the process is backward, the cost will increase, and the price will be higher. Fourth, the economic level, tax policies, transportation costs, etc. of different regions will make prices vary.
In the era of Tiangong Kaiwu, although there was no production of this compound, the prices of various products discussed in the book also changed depending on the region, season, supply and demand. In this analogy, 2-Hydroxy-6-methoxypyridine prices are also changing dynamically. To know the exact price range today, it is advisable to consult chemical product suppliers, trading platforms or industry professionals, and synthesize multi-party information to obtain a relatively accurate price range.
