2 - benzylaminopyridine is an organic compound with unique physical properties. This substance is mostly solid under normal conditions, and it appears to be white to light yellow powder or crystalline, like fine snow or tiny grains, with fine texture.
When talking about the melting point, it is about a specific range, and this property is crucial for identification and purification. When heated to this melting point, it gradually changes from a solid state to a liquid state, just like ice and snow melt when warm.
The boiling point also has a certain value. When the temperature rises to the boiling point, it will change from a liquid state to a gas state and evaporate under certain conditions. < Br >
Its solubility also has characteristics. In organic solvents such as ethanol and dichloromethane, it has good solubility, just like salt dissolves in water, and can be evenly dispersed; while in water, its solubility is poor, just like oil and water are difficult to blend.
In terms of density, it has a specific value. Compared with other substances, it can help determine its position in the mixture. If the density is greater than water, it will sink to the bottom.
In addition, it may also have a faint special smell. Although it is not strong and pungent, it can be detected by carefully sniffing it.
These physical properties are essential for studying their preparation, separation, storage, and behavior in chemical reactions, and are an indispensable foundation for understanding this compound.

The stability of the chemical properties of 2-benzylaminopyridine depends on many factors. The stability of this substance varies under different conditions.
In the environment of room temperature and pressure and no active reagents coexist, its structure is relatively stable. Because of the aromatic nature of the pyridine ring, the electron cloud is evenly distributed, which endows the molecule with certain stability; the presence of benzyl and amino groups, although it has a slight impact on the electron cloud density of the pyridine ring, does not drastically change its inherent stability.
However, in case of high temperature, 2-benzylaminopyridine may change. Under high temperature, the intra-molecular energy increases, the vibration of chemical bonds intensifies, or some weaker bonds are broken. For example, the bond between benzyl and amino groups may be cleaved due to increased energy, causing changes in molecular structure.
Furthermore, when encountering specific chemical reagents, its stability is also challenged. Such as strong oxidizing agents, benzyl can be oxidized to make the molecular structure unrecognizable; when encountering strong acids and bases, nitrogen atoms of amino groups or pyridine rings, or due to protonation or nucleophilic reactions, the molecule undergoes chemical transformation.
The stability of 2-benzylaminopyridine is not absolute. It is more stable at room temperature and pressure without active reagents, and it is prone to changes at high temperatures or in contact with specific reagents. When experimenting and applying, the conditions must be carefully observed to ensure that its properties and structures are controllable.

There are several common methods for synthesizing 2-benzylaminopyridine as follows.
First, 2-chloropyridine and benzylamine are used as raw materials. In an appropriate reaction vessel, 2-chloropyridine and benzylamine are placed, and an appropriate amount of acid binding agent, such as potassium carbonate, is added. Dissolve it in a suitable organic solvent, such as toluene. Heat up to a suitable temperature, usually at 80-120 ° C, and stir the reaction for several hours. In this reaction, the amino nucleophilic of benzylamine attacks the chlorine atom of 2-chloropyridine, and a nucleophilic substitution reaction occurs. The chloride ions leave to form 2-benzylaminopyridine. After the reaction is completed, the product can be obtained through liquid separation, washing, distillation and other operations.
Second, use 2-aminopyridine and benzyl halide as raw materials. Take 2-aminopyridine and dissolve it in a suitable solvent, such as N, N-dimethylformamide. Add an appropriate amount of alkali, such as sodium hydride, to form negative ions of the amino group of 2-aminopyridine to enhance its nucleophilicity. Then slowly add benzyl halide, such as benzyl bromide or benzyl chloride. React at an appropriate temperature, about 20-50 ° C. The benzyl positive ion of benzyl halide combines with the amino negative ion of 2-aminopyridine to form 2-benzylaminopyridine. At the end of the reaction, the product is purified by water quenching reaction, and then by extraction, column chromatography and other steps.
Third, pyridine-2-formaldehyde and benzylamine are used as starting materials. The two are mixed in a solvent, and an appropriate amount of reducing agent is added, such as sodium borohydride or sodium cyanoborohydride. The aldehyde group of pyridine-2-formaldehyde undergoes a condensation reaction with benzylamine to form an imine intermediate, and then the reducing agent reduces the imine to an amino group to obtain 2-benzylaminopyridine. After the reaction is completed, the solvent is removed and the product is purified by recrystallization.

2-Benzylaminopyridine, in the market price, it is difficult to have a fixed number. Due to the complex market conditions, its price often varies with many factors.
Looking at the past city, the abundance of raw materials is the main reason that affects its price. If the raw materials are abundant and the supply is smooth, the price may stabilize or even fall. On the contrary, if the raw materials are scarce and the supply is blocked, the price will rise. It is the situation of raw materials, such as undercurrents in the market, that lurks and causes the price to fluctuate.
And the skill of production also affects its price. Sophisticated techniques can reduce the consumption of production and increase the amount of output. In this way, the price of the market may be close to the people. If the skill is not enough, the production consumption is large and the quantity is small, the price will not be able to go down. The change of this skill is like the direction of the market, guiding the trend of the price.
The demand of the market is more like a wave, stimulating the fluctuation of its price. If there are many people who want it, but the supply is not enough, the price will rise. If there is a lack of supply and a lot of supply, the price is at risk of falling. And the rise and fall of the industry, the direction of policy, is also related to the price. If the industry is prosperous, the policy will help, the production will increase, and the price will stabilize or decline; if the industry is weak, the policy will suppress, the production will decrease, and the price will rise. < Br >
According to normal conditions, the price of 2-benzylaminopyridine is between tens of yuan and hundreds of yuan per kilogram. However, this is only an approximate number and is not an exact value. The market conditions are ever-changing, and if you want to know the real-time price, you should carefully observe the market of chemical raw materials, or consult the merchants and brokers in the industry to obtain the near-real price.
