2-Aminopyridine-4-methanol

2-Aminopyridine-4-methanol is one of the organic compounds. It is weakly basic. Due to the presence of amino groups, the nitrogen atoms in the amino groups have lone pairs of electrons and can accept protons, so it is weakly basic. In an acidic environment, it is easy to combine with protons to form corresponding cations.
This compound has special solubility. In polar solvents such as water and alcohols (such as methanol and ethanol), it has certain solubility. This is because the amino groups and methanol groups in the molecule are polar, which can form hydrogen bonds with polar solvent molecules to improve solubility. However, in non-polar solvents (such as benzene and n-hexane), the solubility is poor. The chemical properties of 2-aminopyridine-4-methanol are active. Amino groups can participate in many reactions, such as reacting with acyl chloride and anhydride to form amide compounds, which is a common method for forming amide bonds in organic synthesis. Methanol groups can also react, for example, under appropriate conditions, they can be oxidized to aldehyde groups or carboxyl groups. If treated with suitable oxidants, methanol groups can be gradually oxidized to obtain aldehyde first, and then further oxidized to carboxylic acids.
In addition, the compound has certain electron delocalization properties due to the conjugated structure of the pyridine ring, which affects its reactivity and stability. In the field of organic synthesis, it is often used as a key intermediate for the preparation of a variety of biologically active compounds, drug molecules, etc., and is of great value in the fields of medicinal chemistry and organic synthesis chemistry.

The common synthesis methods of 2-aminopyridine-4-methanol are important in the field of organic synthesis. There are many methods, and the following are selected.
First, the method using 2-aminopyridine-4-carboxylic acid as the starting material. First, 2-aminopyridine-4-carboxylic acid is reacted with a suitable reducing agent, such as sodium borohydride ($NaBH_4 $) or lithium aluminum hydride ($LiAlH_4 $), in a suitable solvent, such as tetrahydrofuran (THF). Sodium borohydride is relatively mild in reduction, while lithium aluminum hydride is more powerful. Taking sodium borohydride as an example, the temperature needs to be controlled during the reaction. Generally, it starts at a low temperature, such as about 0 ° C, and gradually rises to room temperature to make the reaction proceed smoothly. In this process, sodium borohydride provides hydrogen negative ions, reduces carboxyl groups to hydroxymethyl groups, and obtains 2-aminopyridine-4-methanol.
Second, start from 2-amino-4-halopyridine. React 2-amino-4-halopyridine (such as 2-amino-4-chloropyridine) with metal magnesium to make Grignard reagent. Afterwards, the Grignard reagent is reacted with formaldehyde or paraformaldehyde in anhydrous ether or THF and other solvents. The carbon-magnesium bond of the Grignard reagent has strong nucleophilicity and can attack the carbonyl carbon of formaldehyde. After hydrolysis treatment, the target product 2-aminopyridine-4-methanol is obtained. In this process, the anhydrous and anaerobic requirements of the reaction system are quite high to prevent the failure of the Grignard reagent.
Third, a multi-step synthesis method using pyridine as the starting material. First, pyridine is substituted at a specific position, a suitable functional group is introduced, and then the target structure is gradually constructed through multi-step reaction. For example, a suitable substituent is introduced at the 4th position of pyridine first, and then 2-aminopyridine-4-methanol is finally synthesized through amination, reduction and other steps. Although this route is complicated, it can be flexibly adjusted according to the raw materials and reaction conditions.
The above synthesis methods have their own advantages and disadvantages. In practical application, it is necessary to comprehensively consider the availability of raw materials, cost, difficulty of reaction conditions and other factors, and choose the best one.

2-Aminopyridine-4-methanol, the price of this substance in the market is difficult to determine. The price of the cover often changes for various reasons, just like the illusion of the situation, which is elusive.
First, the price of raw materials is of great importance. If the raw materials required for its preparation are easy to obtain and affordable, the price of 2-aminopyridine-4-methanol may also be close to the people; on the contrary, if the raw materials are scarce and the price is rare, the price of the finished product will rise accordingly.
Second, the state of supply and demand is also the key. In the market, if there are many people who want it, but there are few people who can supply it, the price will rise; if there are few people who want it, the supply will exceed the demand, and the price will drop.
Third, the complexity and simplicity of the production method also affects its price. If the preparation method is simple, it saves labor and time, the cost will be low, and the price will also be low; if the production method is complicated, time-consuming and laborious, the cost will increase greatly, and the price will also be high.
Fourth, the quality of the quality also affects the price. Those with high quality are always high; those with slightly inferior quality, the price may be low.
Looking at the current market, it is difficult to determine the actual situation. If you want to know the price, you must visit the chemical raw material suppliers, or observe the dynamics of the market, in order to get a more accurate price. Or on the chemical trading platform, check the trend of its price in detail, and you can also get its approximation. However, the price changes at any time, and it is appropriate to pay attention to it.
