2-Methyl-4-aminopyridine is also an organic compound. It has various physical properties, let me tell them one by one.
Looking at its morphology, under room temperature and pressure, it is mostly white to light yellow crystalline powder, which is easy to observe and use. Its melting point is about 88-92 ° C. The characteristics of the melting point are quite useful in the identification and separation of substances. When the temperature rises to the melting point, the substance gradually melts from the solid state to the liquid state, and this transformation process can help to identify its purity and other properties.
Furthermore, its solubility is also an important physical property. 2-Methyl-4-aminopyridine is soluble in water. Because its molecular structure contains polar groups, it can form hydrogen bonds with water molecules, so it has a certain solubility in water. And it can also be soluble in common organic solvents, such as ethanol, methanol, acetone, etc. This solubility characteristic has a key impact on the choice of medium for its participation in reactions in the fields of organic synthesis and drug preparation. The boiling point of
cannot be ignored. Although the exact value will vary slightly due to experimental conditions, it is roughly within a certain range. The boiling point reflects the energy required for a substance to change from a liquid state to a gas state, which is related to the stability and volatility of the substance during heating and other operations. The boiling point of 2-methyl-4-aminopyridine reflects the difficulty of liquid gasification under a specific pressure, and is an important consideration in chemical production, distillation separation and other processes.
In addition, the substance has a certain smell, although it is not pungent and unpleasant, it also has its own unique smell. This odor characteristic can be used as the basis for preliminary identification and judgment in actual operation and use. At the same time, the generation of odor is related to molecular structure and volatility. The vibration and volatilization of molecules into the air interact with olfactory receptors to have odor perception.
It can be seen from the above that the physical properties of 2-methyl-4-aminopyridine, such as morphology, melting point, solubility, boiling point, odor, etc., are indispensable in many fields such as chemical industry and medicine. Key information helps researchers and producers to understand and use this substance rationally.

The synthesis of 2-methyl-4-aminopyridine has been known for a long time. One method is to take 2-methyl-4-aminopyridine as the initial substance. React it with appropriate reagents and introduce specific substituents. If the mixed acid of nitric acid and sulfuric acid is used, under suitable temperature and conditions, 2-methyl-4-nitropyridine is nitrified to obtain 2-methyl-4-nitropyridine. This step requires careful temperature control. Due to excessive temperature, side reactions can easily occur, which affects the purity and yield of the product.
After 2-methyl-4-nitropyridine is obtained, the reduction technique is performed. Nitro groups are often reduced to amino groups in a system of iron powder and hydrochloric acid, or hydrogen under the action of catalysts such as palladium and carbon, to obtain 2-methyl-4-aminopyridine. When reducing with iron powder and hydrochloric acid system, the amount of iron powder, the concentration of hydrochloric acid and the reaction time are all key factors. Fine regulation is required to make the reaction proceed smoothly and obtain a pure product.
Another method is to use 4-aminopyridine as the starting material. It is methylated first, and methylation reagents such as iodomethane or dimethyl sulfate can be selected. In an alkaline environment, the nucleophilicity of the nitrogen atom of 4-aminopyridine is enhanced, and it is easier to react with methylating reagents to form 2-methyl-4-aminopyridine. In this process, the type and amount of base and the choice of reaction solvent will affect the reaction. If potassium carbonate is used as the base and acetonitrile is used as the solvent, the reaction can be carried out under milder conditions, reducing the occurrence of side reactions and improving the yield of the product.
In addition, there are also literature records that the structure of 2-methyl-4-aminopyridine is constructed by multi-step reaction with pyridine derivatives as raw materials. Although the steps of this method are slightly complicated, if the reaction route can be reasonably designed and the selectivity of each step can be skillfully used, the target product can also be obtained. And under special needs, the product can be structurally modified by this multi-step synthesis method to endow it with more unique properties.

2-Methyl-4-aminopyridine is also a chemical substance. During storage and transportation, many matters need to be paid attention to.
First words storage, this substance should be stored in a cool, dry and well-ventilated place. Because of its certain chemical activity, high temperature and humid environment, it is easy to cause deterioration and damage its quality. Be sure to keep away from fires and heat sources to prevent unexpected chemical reactions, which may cause fire or explosion. And should be stored separately from oxidizing agents, acids, etc. These substances come into contact with it, or react violently, endangering safety. Where stored, suitable materials should be prepared to contain leaks to prevent accidental leakage and difficult to dispose of in time.
As for transportation, there are also many details. Before transportation, it is necessary to ensure that the packaging is complete and sealed to prevent it from leaking and volatilizing. During transportation, the speed should not be too fast, nor should it be braked abruptly to avoid damage to the packaging. Transportation vehicles must be equipped with corresponding varieties and quantities of fire-fighting equipment and leakage emergency treatment equipment. Escort personnel must be familiar with the nature, hazard characteristics and emergency handling measures of the chemical. During transportation, it should not be mixed with other contraindicated items. When docking for rest, it should also be kept away from sensitive areas such as fire sources and residential areas. In this way, the safety of 2-methyl-4-aminopyridine during storage and transportation should be guaranteed.

The market price range of 2-methyl-4-aminopyridine is difficult to determine. Its price often fluctuates due to changes in market conditions, supply and demand balances, differences in quality, and even factors such as origin and season.
Looking at the market conditions of the past, the price of this product may fluctuate between tens of yuan and hundreds of yuan per kilogram. If the market supply is abundant and there are few buyers, the price may decrease to tens of yuan per kilogram; however, when the demand is strong and the supply is limited, the price may soar, reaching hundreds of yuan per kilogram.
Furthermore, the purity of the product is also a key influence on the price. The price of high-purity 2-methyl-4-aminopyridine is often higher than that of ordinary purity because it is difficult to prepare, requires more refined process and stricter control. In addition, the amount of purchase also affects, bulk purchasers, or get preferential prices due to large quantities.
To know its accurate market price, you should carefully observe the recent market conditions of chemical raw materials, consult suppliers, distributors, or refer to the prices quoted by professional chemical information platforms to understand the approximate current price.
