The synthesis of 5-cyano-2-amino-3-methylpyridine is an important topic in the field of organic synthesis. There are many common routes to synthesize this compound.
One of them can be converted from the functional groups of pyridine derivatives. First, take a suitable parent pyridine and introduce cyano, amino and methyl groups at a specific position. For example, using 2-halo-3-methylpyridine as a starting material, using cyanide reagents, such as potassium cyanide or sodium cyanide, under appropriate reaction conditions, the halogen atom is replaced by a cyano group to generate 2-cyano-3-methylpyridine. Subsequently, the cyano group is partially converted into an amino group by a suitable amination reagent, such as an ammonia derivative or a system of ammonia and a suitable catalyst, to obtain 5-cyano-2-amino-3-methylpyridine. In this process, it is necessary to precisely control the reaction temperature, reaction time and reagent dosage to ensure the smooth progress of the reaction and improve the yield and purity of the product.
Second, the strategy of constructing a pyridine ring can also be adopted. A chain compound containing a specific substituent is used as the starting material to form a pyridine ring through cyclization reaction, and the target substituent is introduced at the same time. For example, selecting a chain molecule containing cyano, amino and methyl latent groups, under the action of acid, base or metal catalyst, the intramolecular cyclization reaction occurs to construct a pyridine ring structure, and then obtain 5-cyano-2-amino-3-methyl pyridine. The key to this method is to design a suitable chain precursor and optimize the cyclization reaction conditions to promote the reaction to proceed efficiently in the direction of the target product.
Furthermore, the coupling reaction catalyzed by transition metals can also be used. Using pyridine derivatives containing different substituents as substrates, transition metal catalysts, such as palladium, nickel and other complexes, were used to couple them with cyanylation reagents and aminylation reagents. Under precise control of the reaction conditions, cyano and amino groups were introduced at specific positions in the pyridine ring, and 5-cyano-2-amino-3-methylpyridine was successfully synthesized. This path requires high activity and selectivity of catalysts, and careful screening of catalysts and ligands is required to optimize the reaction conditions in order to achieve the ideal synthesis effect.
All these synthesis methods have their own advantages and disadvantages. In practical applications, appropriate synthesis strategies must be carefully selected according to many factors such as the availability of raw materials, the ease of control of reaction conditions and product requirements, so as to achieve the efficient and high-purity synthesis of 5-cyano-2-amino-3-methylpyridine.

5-Cyano-2-amino-3-methylpyridine, this is an organic compound. Its physical properties are quite important and are related to many chemical applications.
Looking at its appearance, it is often in the form of a white to off-white crystalline powder, which is delicate and regular, and this form is easy to identify and operate. Its melting point is also a key physical property, which is about a specific temperature range. This temperature is the node of the transition between solid and liquid states, which has a great impact on the thermal stability and processing of the substance. During the heating process, when this melting point is reached, the substance will gradually melt from a solid state to a liquid state. This property is of great significance in the purification and molding steps of chemical production.
Furthermore, its solubility cannot be ignored. In common organic solvents, such as ethanol, dichloromethane, etc., it has a certain solubility. In ethanol, it is partially soluble due to intermolecular forces, which makes the substance uniformly dispersed in the reaction system using ethanol as a solvent, which is conducive to the progress of chemical reactions. In water, the solubility is relatively poor, because the polarity of the molecular structure and the polarity of water do not match well, making it difficult to dissolve in large quantities.
In addition, the density of this substance also has its own characteristics. Although the exact value needs to be measured experimentally, relatively speaking, the density is moderate. This property affects the stratification and distribution of the substance when it comes to mixing systems, and is crucial for the separation and purification of chemical production.
In conclusion, the physical properties of 5-cyano-2-amino-3-methylpyridine, such as appearance, melting point, solubility, and density, play a crucial role in its application in chemical synthesis, drug discovery, and materials science, and both researchers and producers need to consider them in detail.

In today's world, it is not easy to know the market price of 5-cyano-2-amino-3-methylpyridine. The price of these chemicals often fluctuates for a variety of reasons.
First, the situation of supply and demand is the key. If there are many people in the market, but there are few products, the price will rise; conversely, if the supply is abundant and the demand is thin, the price may fall.
Second, the price of raw materials also has a great impact. The production of 5-cyano-2-amino-3-methylpyridine requires various raw materials, and the fluctuation of raw material prices will lead to its own price changes.
Third, the preparation method and process are complicated and simple, which are related to the cost and also related to the selling price. If the preparation technique is excellent, the cost can be reduced, and the price may be cheap; if the process is complicated, the cost is high, and the price is difficult to reduce.
Fourth, the differences in regions also make the price different. There are differences in supply and demand and transportation costs everywhere, and the price varies from place to place.
Looking at "Tiangong Kaiwu", although the ancient books are ancient, they all focus on reality.

According to the quaint style of "Tiangong Kaiwu", this substance should be stored in a dry, cool and well-ventilated place. Because moisture can easily cause the compound to get damp, which in turn triggers many chemical reactions, impairing its purity and properties. If it is placed in a humid place, it may be like being placed in a rain place, and the substance is prone to mildew and rot.
A cool place is indispensable. High temperature can easily enhance the activity of 5-cyano-2-amino-3-methylpyridine molecules, or cause decomposition, polymerization and other reactions. For example, exposure to hot sun, physical properties are variable. And good ventilation is essential to avoid the accumulation of harmful gases, keep the environment safe, and prevent compounds from qualitative change due to depression.
In addition, when storing, it needs to be stored separately from oxidants, acids, bases and other substances. This is because the chemical properties of 5-cyano-2-amino-3-methylpyridine are active, and it is easy to react violently or be dangerous when it encounters the above materials. For storage, corrosion-resistant materials should be used to prevent the device from corroding and damaging its physical properties.
