2-% hydroxy-5-methylfuranopyridine is a unique organic compound with many special physical properties and important value in many fields.
Looking at its properties, under normal temperature and pressure, this substance is mostly in the form of a crystalline solid, and its appearance is often white or nearly white. When pure, it is crystal clear, like fine ice crystals. However, if it contains impurities, its color may change. The crystalline structure of this substance is regular, resulting in a relatively high melting point, which has been accurately determined to be about [X] ° C. The high melting point makes it able to maintain a stable solid state at normal ambient temperature, providing convenience for its storage and transportation.
When it comes to solubility, 2% hydroxy-5-methylfuropyridine exhibits a unique performance in organic solvents. It exhibits good solubility in polar organic solvents such as ethanol and dimethyl sulfoxide, and can interact with solvent molecules through hydrogen bonds, van der Waals forces, etc., and disperse uniformly in it. The solubility in water is relatively limited. Although hydroxyl groups in the molecular structure can form hydrogen bonds with water, the hydrophobicity of the furopyridine skeleton is also strong, and the degree of solubility in water is not high under the action of the two phases. This difference in solubility is of great significance in the separation, purification and practical application of compounds. < Br >
2% hydroxy-5-methylfuranopyridine has a certain volatility. At a specific temperature range, a small amount of molecules can break free from the binding of the solid surface and enter the gas phase. However, compared with low-boiling organic compounds, its volatility is weaker. This property has a significant impact on practical application scenarios, such as chemical reaction systems, storage environments, etc. Weaker volatility can reduce the loss of compounds under normal conditions, and also make the related operation process safer and more controllable.
Its density is also one of the important physical properties. After experimental determination, its density is about [X] g/cm ³. This value reflects the molecular packing density of the compound, which has a direct impact on its sedimentation and dispersion behavior in different media. When preparing composites or mixed systems containing the compound, the density properties provide key parameters for formulation design and process optimization.

2-% hydroxy-5-methylfuranopyridine, although this substance is not detailed in Danish texts, its properties can be known according to current chemical studies.
This compound has unique chemical activity. The presence of its hydroxyl and methyl groups makes it hydrophilic to a certain extent. Hydroxyl groups can participate in many chemical reactions, such as esterification and etherification. During esterification, hydroxyl groups and carboxylic acids can form ester compounds under appropriate catalysts and conditions. This reaction has many applications in the field of fragrance and drug synthesis, and can add specific aromas to the products or change their pharmacological properties.
The methyl group attached to the furanopyridine ring has an impact on the electron cloud distribution and spatial structure of the molecule. Because it is a power supply group, it can increase the electron cloud density on the ring, making the ring more electron-rich. In the electrophilic substitution reaction, the reaction is more likely to occur, and the steric resistance effect of methyl groups also plays a role in the selectivity of the reaction check point.
The core structure of furanopyridine has aromaticity and stability. The electron conjugation of the aromatic system reduces the molecular energy and stabilizes the structure. This structure has also attracted much attention in the field of heterocyclic chemistry, and is often a key building block for organic synthesis and drug development.
Its reactivity in acid and alkali environments is also considerable. In acidic media, nitrogen atoms may be protonated to change the charge distribution and solubility of compounds, thereby affecting their chemical reactivity; under alkaline conditions, hydroxyl groups may be deprotonated to enhance their nucleophilicity and participate in nucleophilic substitution or addition reactions.
In short, 2-% hydroxy-5-methylfuranopyridine has potential applications in chemical synthesis, drug creation, and many other fields due to its unique structure and diverse reactivity. It is one of the important objects of chemical exploration.

To prepare 2-amino-5-methylpyridine, there are various methods. First, it can be obtained by reducing 2-methyl-5-nitropyridine. Take 2-methyl-5-nitropyridine, place it in an appropriate reactor, and add a suitable reducing agent, such as a combination of iron and hydrochloric acid, or hydrogen and a suitable catalyst (such as palladium carbon). If iron reacts with hydrochloric acid, and iron reacts with hydrochloric acid to produce a new hydrogen, this hydrogen can gradually reduce nitro to amino groups. Under a certain temperature and pressure, the reaction process is controlled and monitored in a timely manner. After the reaction is completed, pure 2-amino-5-methylpyridine can be obtained through separation and purification steps, such as extraction, distillation, etc.
Second, 2-chloro-5-methylpyridine is used as raw material and prepared by aminolysis reaction. 2-chloro-5-methylpyridine is co-placed in a reaction vessel with an alcohol solution of liquid ammonia or ammonia, and an appropriate amount of catalyst is added, such as a copper salt catalyst. Under appropriate temperature and pressure, the chlorine atom is replaced by an amino group, and an aminolysis reaction occurs. After the reaction is completed, impurities are removed by means such as filtration and rectification to obtain the target product.
Third, it is synthesized from 2-methylpyridine through two steps of nitration and reduction. First, 2-methylpyridine is reacted with a suitable nitrifying agent, such as a mixed acid of concentrated nitric acid and concentrated sulfuric acid, under specific temperature conditions, and nitro is introduced to generate 2-methyl-5-nitropyridine. This step needs to be carefully controlled to prevent side reactions from occurring. Then, as mentioned earlier, 2-methyl-5-nitropyridine is reduced to obtain 2-amino-5-methylpyridine. Each method has its own advantages and disadvantages. In actual preparation, it is necessary to comprehensively consider factors such as the availability of raw materials, cost, and product purity requirements to choose the appropriate method.
