2-Methyl-3-hydroxypyridine is also an organic compound. Its physical properties are particularly important, and it is related to the wide range of its applications.
Looking at its properties, under normal temperature, it is mostly in a solid state, which is caused by the force between molecules. Its color is either white or close to white, its appearance is pure, and it has a jade-like quality.
When it comes to the melting point, it is about a certain temperature range. The value of this temperature is determined by its molecular structure. The strength of the interaction between molecules has a great influence on the melting point. If the force is strong, a higher temperature is required to break the lattice and cause the melting point to rise; otherwise, it is low. < Br >
The boiling point is also one of the important physical properties. At this temperature, the substance changes from liquid to gaseous. The boiling point of 2-methyl-3-hydroxypyridine also depends on factors such as its intermolecular force and relative molecular weight. The larger the relative molecular weight, the stronger the intermolecular force, and the higher the boiling point.
In terms of solubility, it is soluble in some organic solvents. When the polarity of organic solvents is similar to that of 2-methyl-3-hydroxypyridine molecules, it is easily soluble. For example, common organic solvents such as ethanol and acetone have good miscibility with them. In water, its solubility varies according to specific conditions, because the polarity of water does not exactly match the polarity of the compound.
In addition, density is also one of its physical properties. The value of its density reflects the mass of the substance per unit volume. Compared with other substances, it can be seen that its weight is different. In practical applications, such as separation and mixing, this property needs to be considered.

2-Methyl-3-hydroxypyridine, this material is unique, and it has the characteristics of both alkali and acid. Its pyridine ring is aromatic, and the distribution of electron clouds is caused, so it is weakly basic and can form salts with strong acids. And its hydroxyl group is subject to the electronic effect of the pyridine ring, hydrogen is easy to dissociate, and it is acidic to a certain extent, which can react with bases.
Its solubility also has characteristics. In polar solvents such as water and alcohols, the hydroxy group can form hydrogen bonds with solvent molecules, so the solubility is good; in non-polar solvents such as alkanes, the solubility is poor.
In terms of thermal stability, the structure of this compound is relatively stable, and a higher temperature is required to cause it to decompose. However, at high temperatures or under specific conditions, there will be reactions between the pyridine ring or the hydroxyl group, such as dehydration of the hydroxyl group and conversion of the substituent on the pyridine ring.
In terms of chemical activity, the electron cloud distribution of the pyridine ring makes it electrophilic substitution reaction, which is more difficult than benzene, and the substitution check point is mostly at the higher electron cloud density. Hydroxyl groups can participate in many reactions, such as esterification, etherification, etc., due to the lone pair of electrons of oxygen atoms and the activity of hydrogen. The complexity and diversity of its chemical properties provide many possibilities and applications for organic synthesis and other fields.

The synthesis method of 2-methyl-3-hydroxypyridine has been known for a long time, and after many talents have explored, several common ones are described.
First, pyridine derivatives are used as starting materials. First, take a suitable pyridine compound and introduce methyl groups through a specific substitution reaction. This process requires careful selection of reaction conditions, such as temperature and catalyst. Common catalysts, such as some metal salts, catalyze the reaction of methylating reagents with pyridine rings in a specific solvent environment. After the methyl group is successfully introduced, a hydroxyl group is generated by oxidation or other functional group conversion reactions at a specific position of the pyridine ring. This step also requires delicate control of the reaction conditions to ensure that the hydroxyl group is precisely formed at the target position.
Second, synthesize with a nitrogen-containing heterocyclic construction strategy. Suitable small organic molecules can be selected to construct a pyridine ring structure through a multi-step reaction. First, a condensation reaction is used to connect the nitrogen-containing compound with other organic fragments to form the prototype of the pyridine ring. During the construction process, the reaction sequence can be cleverly designed so that methyl and hydroxyl groups are introduced simultaneously or step by step at suitable stages. For example, before or after the cyclization reaction, methyl and hydroxyl groups are introduced respectively. This process requires fine regulation of the process and selectivity of each step of the reaction.
Third, biosynthesis is also feasible. Some microorganisms in nature have specific metabolic pathways and can use specific substrates to synthesize nitrogen-containing heterocyclic compounds. By screening microorganisms with such abilities and optimizing their culture conditions, such as medium composition, temperature, pH, etc., microorganisms can efficiently synthesize 2-methyl-3-hydroxypyridine. Although this method has the advantages of green environmental protection, the process of microbial culture and product separation is relatively complicated, and in-depth study of microbial metabolic mechanisms and separation and purification technologies is required.
The above methods have their own advantages and disadvantages. Although the chemical synthesis method has complicated steps, it can precisely control the product structure; the biosynthesis method is green and environmentally friendly, but the technical difficulty is high. All synthesis methods are the crystallization of the wisdom of talents in the field of chemistry, and future generations should continue to study and improve them in order to achieve the delicate realm of synthesis.

Looking at the market conditions in the city, the price of things often varies with time, place and quality. As for the price of 2-Methyl-3-hydroxylpyridine, it is difficult to determine the value. The price of a chemical substance is influenced by many reasons.
First, it is difficult and easy to make. If the technology is complex, the materials required are expensive and the labor force is large, the price will be high; if it is easy to make, the materials are easy to obtain, and the labor is saved, the price will be low.
Second, the city's demand and supply. If there are many seekers, if the supply is small, the price will rise; if the demand is scarce, if the supply is large, the price will fall.
Furthermore, the quality is good or bad. < Br >
There is also competition in the market, where merchants compete for sale, or reduce their prices to attract customers; for sole sellers, the price may be set by them.
Looking at the principles of "Tiangong Kaiwu", everything has its source, and the price also changes. To know the exact price of 2-Methyl-3-hydroxylpyridine, one should carefully study the state of the city, consult merchants, observe the state of supply, observe the quality, etc., to obtain an approximate number. However, the market is not constant, and the price is not constant, so it is difficult to determine the price range of a definite value. Or the top and bottom of a hundred gold, or the difference between a few gold, all vary according to the real situation of the city.
