This is a chemical name. If its chemical structure is described in the ancient classical Chinese style of "Tiangong Kaiwu", it should be as follows:
This compound is called benzyl 4- (aminomethyl) tetrahydro-1 (2H) -pyridinecarboxylate. In its structure, benzyl is connected to the group of benzene cyclic methylene, which is like an ancient crown, with benzene ring as the crown apex and methylene as the cymbidium sagging. 4- (aminomethyl), in the fourth position of the pyridine ring, is connected with aminomethyl, which extends like branches, ammonia is the stem of the branch, and methyl is the side leaf. In the case of tetrahydro-1 (2H) -pyridine, the pyridine ring is hydrogenated, with the addition of tetrahydrogen atoms, so that the saturation of the ring changes, just like the original regular pavilion, with tiles and eaves, and the shape is slightly changed. And at the 1 (2H) position, this is the positioning mark, which determines the specific position in its structure. And the carboxylic acid ester is a structure containing carbonyl groups and alkoxy groups connected, such as the intersection of the pillars of the building. The carbonyl group is the key to the intersection of the beams, and the alkoxy group is the supporting beam, which together constitute the unique structure of this compound. The chemical structure of benzyl 4- (aminomethyl) tetrahydro-1 (2H) -pyridinecarboxylate is obtained by combining all these with each other.

The synthesis of benzyl 4- (aminomethyl) tetrahydro-1 (2H) -pyridinecarboxylate is a crucial research topic in the field of organic synthesis. There are various synthetic paths, each path is unique, and it needs to be carefully selected according to the actual situation.
One method can start from common pyridine derivatives. First, the pyridine ring is specially modified, and a suitable functional group is introduced at the 4-position to lay the foundation for the subsequent introduction of aminomethyl. This step may require a halogenation reaction to halogenate the pyridine ring at the 4-position to generate 4-halogenated pyridine derivatives. The activity of the halogen atom creates conditions for the subsequent nucleophilic substitution reaction.
Then, by nucleophilic substitution reaction, the aminomethyl group is introduced into the 4-position. Nucleophilic reagents containing aminomethyl groups can be selected to react with 4-halogenated pyridine derivatives under appropriate reaction conditions. The control of reaction conditions is extremely critical, such as reaction temperature, reaction time, solvent selection, etc., which will affect the yield and selectivity of the reaction.
Furthermore, the construction of tetrahydropyridine ring is also a key step. Or catalytic hydrogenation can be used to partially hydrogenate the pyridine ring to form a tetrahydropyridine structure. In this process, the choice of catalyst is quite important, and the reaction activity and selectivity of different catalysts vary significantly.
At the same time, when synthesizing the benzyl ester part, the esterification reaction can be used. Suitable benzyl alcohol is reacted with tetrahydropyridine derivatives containing carboxyl groups to form the target product benzyl 4- (aminomethyl) tetrahydro- 1 (2H) -pyridinecarboxylate. The esterification reaction also needs to pay attention to the reaction conditions, such as the amount of acid catalyst, the dehydration of the reaction system, etc., in order to promote the reaction to proceed in the direction of ester formation.
When synthesizing this compound, the connection between each step and the purification of the intermediate product cannot be ignored. After each step of the reaction, the product is properly separated and purified to ensure the smooth development of the next step of the reaction, thereby improving the purity and yield of the final product.

The physical and chemical properties of benzyl 4- (aminomethyl) tetrahydro-1 (2H) -pyridinecarboxylate are as follows:
In appearance, it is often white to white solid powder, and the texture is fine. It is like the thin snow that falls in the early winter, pure and uniform. Its melting point range is roughly in a specific range, about [X] ° C - [X] ° C. Within this temperature limit, this substance gradually melts from solid to liquid, just like ice and snow melting in the warm sun.
In terms of solubility, it shows a certain solubility in organic solvents, such as methanol, ethanol and other alcoholic solvents, just like fine sand blending into running water, and can be well mixed with it. In organic solvents with weaker polarity, such as ether, the solubility is relatively limited. In water, the solubility is quite low, just like oil droplets in water, it is difficult to blend, and its hydrophilic properties are poor due to its molecular structure characteristics.
In terms of stability, in a dry environment at room temperature and pressure, this material is quite stable in nature, and can be stored for a long time without easy chemical changes. It is like a rock in a mountain, as stable as Mount Tai. However, if it is placed under high temperature, high humidity or strong light irradiation, its stability will be affected, and the molecular structure may gradually change, just like an ice sculpture under the hot sun, gradually deforming.
Its density is about [X] g/cm ³, which is similar to the density of common organic compounds. Like objects of specific materials, it has its own specific weight and volume ratio. In chemical reactions, the functional groups such as aminomethyl and ester groups contained in the molecule make it have unique reactivity. Aminomethyl can participate in many nucleophilic reactions, and ester groups can undergo hydrolysis, alcoholysis and other reactions. It is like a skilled craftsman with a variety of skills, showing its unique role in different chemical reaction stages.

Wen Jun inquired about the price range of "BENZYL + 4- (AMINOMETHYL) TETRAHYDRO-1 (2H) -PYRIDINECARBOXYLATE" in the market. However, the price of this product is difficult to determine. The price is affected by various factors, such as differences in origin, differences in quality, changes in market supply and demand, and even the simplicity of the preparation process.
If the origin is abundant, the raw materials are abundant, and the process is refined and mature, the price may be slightly easier; on the contrary, if the origin is remote, the raw materials are scarce, and the preparation is difficult, the price will be high. And the market supply and demand are changing rapidly, and if the demand exceeds the supply, the price will rise; if the supply exceeds the demand, the price will be depressed.
In addition to this compound, or due to its specialized use, the audience is limited, and its circulation in the market also has its own regulations. In the field of scientific research or pharmaceutical research and development, the demand is different, and the price is also different.
Therefore, in order to know its exact price, it is necessary to study the market situation in detail, consult various suppliers, and compare different channels to obtain a more accurate price. However, it is difficult to determine the range of its price only according to the existing situation.
