To prepare 2-amino-3-hydroxy-6-methylpyridine, there are various methods.
First, the corresponding pyridine derivative can be obtained through a specific substitution reaction. First, find a suitable pyridine parent, whose structure needs to have a check point that can be substituted by amino, hydroxyl and methyl groups. Taking halogenated pyridine as an example, the amino group is introduced by reacting with ammonia under suitable conditions. This process requires fine regulation of the reaction temperature, pressure and the ratio of reactants, so that the halogen atom is replaced by an amino group. Subsequently, through the hydroxylation reaction, the hydroxyl group can be introduced at the designated position by means of nucleophilic substitution or oxidation. Finally, with the help of methylating reagents, such as iodomethane, methyl groups are introduced under appropriate conditions to obtain the target product 2-amino-3-hydroxy-6-methylpyridine.
Second, pyridine rings can be gradually constructed from simple raw materials. For example, small molecular compounds containing nitrogen, oxygen and carbon are used as starting materials. First, the nitrogen-containing compound and the carbonyl-containing compound undergo a condensation reaction to preliminarily construct the skeleton of the nitrogen-containing heterocyclic ring. Then through a series of reactions, such as reduction and substitution, amino, hydroxy and methyl groups are gradually introduced into the ring. This route requires careful design of the reaction sequence and conditions at each step to ensure that each functional group can be introduced and converted in the expected manner, so as to efficiently synthesize 2-amino-3-hydroxy-6-methylpyridine.
Third, the synthesis path of similar compounds can be referred to, combined with the structural characteristics of the target product, to improve the existing method. For example, drawing on the successful strategy of introducing amino, hydroxy and methyl in the synthesis of other pyridine derivatives, targeting the special structure of 2-amino-3-hydroxy-6-methylpyridine, optimize the reaction conditions, adjust the activity and selectivity of the reactants, and achieve the purpose of efficient synthesis. In this way, after considering and trying various strategies, 2-amino-3-hydroxy-6-methylpyridine can be obtained.

2-% hydroxy-3-methoxy-6-methylpyridine is an organic compound, which is very important in the chemical and pharmaceutical fields. Its physical properties are as follows:
- ** Properties **: Under normal conditions, it is mostly colorless to light yellow liquid, but the purity and environment vary, or it appears different, or it is a crystalline solid, which is related to the intermolecular force and arrangement.
- ** Boiling point **: The melting point is about -15 ° C, and the boiling point is between 210-212 ° C. The melting point is low, due to the non-strong intermolecular force, when heating up, the molecule is easy to obtain enough energy to get rid of the binding, from solid to liquid; the boiling point is higher, because the liquid time needs more energy to overcome the interaction, and the liquid surface escapes into a gaseous state.
- ** Solubility **: It can be soluble in organic solvents such as ethanol and ether, and also has a certain solubility in water. Because the molecule contains hydroxyl and methoxy polar groups, it can form hydrogen bonds or other interactions with water and organic solvents, so it can be dissolved.
- ** Density **: about 1.06 g/cm ³, slightly larger than water, indicating that the mass of the substance is slightly heavier at the same volume, which is related to the molecular composition and the degree of accumulation. < Br > - ** Odor **: has a special odor, although it is difficult to describe accurately, it can be identified by regular contacts, and can be perceived in the air due to its volatility.

There are 2-hydroxy-3-methoxy-6-methylpyridine available today. I would like to know what its price is on the market. This product is useful in many fields such as medicine and chemical industry. However, its price varies for many reasons.
The first to bear the brunt is the purity. If the purity is high, it is almost pure, and impurities are rare, the price will be high. Because the purification process requires exquisite techniques and consumes a lot of material resources and manpower, its price is high. If the purity is slightly lower and contains some impurities, although it can be used in some common places, the price must be lower than that of pure products.
Furthermore, the output also affects its price. If the product is abundant in the market and the supply is large, the price may stabilize and be slightly lower according to the principle of supply and demand. On the contrary, if the output is scarce and the supply exceeds the demand, the merchant may raise the price in order to make a big profit.
The difference in origin also has an impact. In different places, the price is different due to the amount of resources, the quality of the process, and the cost. If a place is rich in resources, the process is excellent, and the cost is controllable, the price of the output may have an advantage.
In addition, the market demand is also the key. If the demand for pharmaceutical research and development and chemical production surges at a certain time, and the supply is difficult to respond for a while, the price will rise. If the demand is low, the merchant will sell the goods, or reduce the price.
As far as I know, 2-hydroxy-3-methoxy-6-methylpyridine is currently available in the market, with high purity, up to several hundred gold per kilogram; followed by purity, ranging from one kilogram or one or two hundred gold. However, this is only a rough figure, the market situation is fickle, and the price fluctuates accordingly. If you want to know the exact price, you should consult the chemical raw material merchants and market brokers in detail.

The storage conditions of 2-% hydroxy-3-methoxy-6-methylpyridine are crucial to the maintenance of its quality and utility. According to the concept of "Tiangong Kaiwu", the storage of such chemicals should follow the following principles.
Dry humidity of the first environment. It should be placed in a dry place and avoided in a humid place. Because moisture can easily lead to deliquescence of substances, or cause them to chemically react with water, damaging their inherent structure and properties. In a humid environment, water molecules may interact with 2-% hydroxy-3-methoxy-6-methylpyridine, causing hydrolysis and other reactions of hydroxyl groups, methoxy groups, etc., causing the substances to deteriorate and lose their original functions.
The second is the control of temperature. It should be stored in a cool place, away from high temperature and fire sources. High temperature is easy to increase molecular activity, triggering various chemical reactions, such as thermal decomposition, oxidation, etc. 2-% hydroxy-3-methoxy-6-methylpyridine In case of high temperature, methyl, methoxy and other parts may break or rearrange, changing the composition and properties of the substance, and even forming harmful impurities.
Furthermore, it is necessary to prevent excessive contact with the air. Oxygen, carbon dioxide and other components in the air may react with the substance. Oxygen is oxidizing, or 2-% hydroxy-3-methoxy-6-methylpyridine is oxidized, changing its chemical structure. Under specific conditions, carbon dioxide may also participate in the reaction and affect the stability of the substance. Therefore, it should be sealed and stored to reduce contact with air.
In addition, avoid mixing with other chemicals. The chemical properties of different chemicals are different, and mixing can easily lead to unexpected chemical reactions. If 2-% hydroxy-3-methoxy-6-methylpyridine coexists with strong oxidants, strong acids, strong bases and other substances, or due to chemical nature conflicts, it will cause violent reactions, which will not only damage itself, but also may cause safety accidents.
Store 2-% hydroxy-3-methoxy-6-methylpyridine in a dry, cool, sealed environment, and do not mix with other chemicals, so as to ensure the stability of its quality and chemical properties.
