2-Methyl-4-hydroxypyridine is also an organic compound. Its physical properties are quite important and are listed in detail below.
First of all, its appearance, under room temperature and pressure, 2-methyl-4-hydroxypyridine is mostly white to light yellow crystalline powder. This morphological feature can be an important preliminary basis for judgment when actually identifying and operating.
Secondary and melting point, its melting point is about 146-149 ℃. The melting point is the critical temperature at which a substance changes from a solid state to a liquid state. The melting point range of 2-methyl-4-hydroxypyridine is of key guiding significance for its separation, purification and identification in chemical experiments and industrial production. By accurately measuring the melting point, the purity of the substance can be determined. If the actual melting point is consistent with the theoretical value or the deviation is very small, the purity is higher; conversely, if the deviation is large, it may be mixed with impurities.
Furthermore, when it comes to solubility, 2-methyl-4-hydroxypyridine can be soluble in common solvents such as water, ethanol, and acetone. The dissolution in water makes it participate in many chemical reactions in the form of aqueous solutions, expanding its application scope. Soluble in ethanol, acetone and other organic solvents, in the field of organic synthesis, provides a variety of possibilities for the selection of suitable reaction media. Its solubility is closely related to the molecular structure, and the hydroxyl group and pyridine ring contained in the molecule give it a certain polarity, so it can interact with polar solvents to dissolve.
In addition, its stability, under general conditions, 2-methyl-4-hydroxypyridine has a certain stability. However, when encountering strong oxidizing agents, strong acids, strong bases and other substances, the stability is easily destroyed and chemical reactions occur. In case of strong acids, the nitrogen atoms on the pyridine ring are easily protonated, triggering a series of chemical changes; in case of strong bases, hydroxyl groups may participate in the reaction, resulting in molecular structure changes. This stability feature requires that during storage and use, it is necessary to avoid contact with the above substances, usually in a cool, dry and well-ventilated place to prevent deterioration.
In summary, the physical properties of 2-methyl-4-hydroxypyridine, such as appearance, melting point, solubility and stability, are interrelated and have their own uses. They are indispensable information in many fields such as chemical research and industrial production.

2-Methyl-4-hydroxypyridine is one of the organic compounds. Its chemical properties are of great interest and are described in detail as follows:
First of all, its acidity and alkalinity. This compound has the characteristics of both acidity and alkalinity. Because there is a hydroxyl group in the molecule, the hydrogen of the hydroxyl group can be dissociated, so it is acidic; and it also contains the nitrogen atom of the pyridine ring. Nitrogen has solitary pairs of electrons, can accept protons, and is alkaline. This acidity and alkalinity make it suitable as an acid-base catalyst in specific reactions. It participates in many organic synthesis reactions, such as certain esterification and hydrolysis reactions, and can affect the reaction rate and direction by its acidity and alkalinity.
On its nucleophilicity and electrophilicity. The presence of the pyridine ring makes this compound have a certain nucleophilicity. The electron cloud distribution on the pyridine ring is uneven, and the density of the electron cloud at the ortho and para-site of the nitrogen atom is relatively high, making it vulnerable to the attack of electrophilic reagents. The electron-giving effect of the hydroxyl group also affects the distribution of the electron cloud on the ring, strengthening the activity of its nucleophilic site. When encountering electrophilic reagents, such as halogenated hydrocarbons, acyl halides, etc., electrophilic substitution reactions can occur, introducing new groups at specific positions on the ring. On the contrary, the oxygen atom of the hydroxyl group also has nucleophilic properties, which can attack suitable electrophiles, such as reacting with alkylating reagents to generate corresponding ether derivatives.
Re-describe its redox properties. 2-Methyl-4-hydroxypyridine can participate in redox reactions. Hydroxyl groups are easily oxidized and can be converted into higher valence oxygen-containing functional groups such as carbonyl groups. Moderate oxidants, such as mild metal oxides or specific organic oxidants, can facilitate this oxidation process. Under certain reduction conditions, the pyridine ring can be partially reduced, changing its electronic structure and chemical activity, and derived products with different properties, which can be used in organic synthesis to construct compounds with different structures.
and its relationship between stability and reactivity. The structure of 2-methyl-4-hydroxypyridine gives it certain stability, but under suitable conditions, the activity of each functional group allows it to participate in a variety of chemical reactions. The presence of methyl groups affects the electronic effect between the pyridine ring and the hydroxyl group, and regulates the reactivity of the molecule as a whole. This balance of stability and activity allows chemists to precisely control it to participate in various organic reactions under different reaction conditions, synthesizing many organic compounds with specific structures and functions, which are of important application value in pharmaceutical chemistry, materials science and other fields.

I look at your question, but I am inquiring about the market price of 2-methyl-4-hydroxypyridine. However, the market price often changes with time, and also varies with quality, quantity and supply and demand.
In the past, the price of this substance may vary depending on the method of synthesis, the price of raw materials, and the number of labor costs. In the market, if the quality is high and the quantity is abundant, the price may be relatively simple; if the quality is thin and the quantity is small, and the demand is large, the price may be expensive.
Or in the market of chemical raw materials, the price may vary. If you sell it in bulk, the price may be slightly reduced; if you sell it in small quantities, the price may be slightly increased. And because of the production side, there are domestic and imported points, the imported or due to tariffs, freight, price or higher than domestic.
If you want to know the exact price, do not consult the merchants of chemical raw materials in person, or check the recent reports on the platform of chemical trading, in order to obtain the exact market price, and move according to the times, good planning.
