(E)-2-[3-(1-Pyrrolidinyl)-1-p-tolylpropenyl]pyridine hydrochloride

(E) - 2 - [3 - (1 - pyrrolidyl) - 1 - p-toluene propenyl] pyridine hydrochloride, which is one of the organic compounds. Looking at its naming, its chemical structure can be deduced according to the naming rules of organic chemistry.
" (E) " shows that the compound has a specific configuration and is a trans configuration. "2 - [3 - (1 - pyrrolidyl) - 1 - p-toluene propenyl] pyridine", this part clearly shows that its main structure is composed of a pyridine ring, with a specific substituent at the second position of pyridine. The substituent contains a 3- (1-pyrrolidyl) -1-p-toluene propylene-based structure. Among them, "3- (1-pyrrolidyl) " is expressed at the No. 3 position of the propylene group, with 1-pyrrolidyl; "1-p-toluene" refers to the No. 1 position of the propylene group, with p-toluene. And the "hydrochloride salt" shows that the compound forms a salt of hydrochloric acid, that is, the nitrogen atom of the pyridine ring binds a hydrogen ion to form a cation, which equalizes the charge with the chloride ion.
In summary, the chemical structure of (E) -2 - [3 - (1 - pyrrolidyl) -1 - p-toluene propenyl] pyridine hydrochloride is based on the pyridine ring as the core, with a specific substituent at position 2, and forms a hydrochloride state.

(E) - 2 - [3 - (1 - pyrrolidyl) - 1 - p-toluphenylpropenyl] pyridine hydrochloride. Its physical properties are critical and related to many applications.
Its appearance is often a specific form, mostly crystalline, with a white or white-like color. The texture is fine and uniform, and it can be seen under light with a bright luster, like fine stars scattered, which is the characteristic of the naked eye.
When it comes to solubility, it varies in common organic solvents. In alcohol solvents, such as ethanol, can show good solubility, just like ice and snow meet warm sun, slowly melt in it, forming a uniform and translucent solution; in water also has a certain solubility, although not as fast as alcohol, but can also be partially dissolved under appropriate conditions, making the water slightly turbid, like a light cloud cage.
Melting point is an important indicator to measure its physical properties. Experiments have determined that its melting point is in a specific temperature range. When heated to a certain temperature, the lattice structure of this substance gradually loosens, and the molecular movement intensifies, gradually changing from solid to liquid. This temperature range is an important basis for identifying the substance, as if it is a unique temperature imprint on the substance.
In addition, its density is also an inherent property. Under specific conditions, each unit volume has a fixed mass, which is like a substance with its own unique "weight code", reflecting the tight arrangement and composition of its internal molecules. These many physical properties are intertwined, and together outline the unique physical "portrait" of (E) -2- [3- (1-pyrrolidyl) -1-p-toluene propenyl] pyridine hydrochloride, laying the foundation for its application in chemical, pharmaceutical and other fields.

(E) - 2 - [3 - (1 - pyrrolidyl) - 1 - p-toluphenylpropenyl] pyridine hydrochloride, which is an organic compound. In the era of "Tiangong Kaiwu", there is no exact record of these compounds. Because it was written in the Ming Dynasty, at that time, chemical science had not yet developed to the extent that such complex organic compounds could be synthesized and recognized.
However, from the perspective of today's chemistry, such compounds may have important uses in many fields. In the field of medicinal chemistry, they may be used as lead compounds for potential drug development due to their unique molecular structure and specific biological activities. Scientists can explore its interaction with biological targets by modifying and optimizing its structure to develop innovative drugs for the treatment of specific diseases.
In the field of materials science, it may be able to participate in the preparation of functional materials. For example, due to structural units such as pyridine and pyrrolidinyl, compounds are endowed with special electrical, optical or self-assembly properties, which can be used to prepare organic optoelectronic materials, sensor materials, etc. Through rational design and synthesis, materials sensitive to specific substances or physical quantities may be prepared to achieve high sensitivity detection.
In the field of organic synthetic chemistry, as a key intermediate, it can participate in the construction of more complex organic molecular structures. Chemists can make use of its double bonds, pyridine ring and pyrrolidinyl reactivity to carry out various organic reactions, expand the structural diversity of organic compounds, and provide new paths and methods for the development of organic synthetic chemistry.

The synthesis method of (E) - 2 - [3 - (1 - pyrrolidyl) - 1 - p-toluphenylpropenyl] pyridine hydrochloride can be obtained from many ways.
First, pyridine is used as a group, and a halogenation reaction is carried out to introduce a halogen atom at a specific position of pyridine. This halogen atom has high activity and can be used as a key check point for subsequent reactions. Then, the p-toluene derivative and the pyrrolidyl-containing compound are taken, and under a suitable base and catalyst environment, through coupling reaction, the three are connected, and the basic structure of the target is preliminarily constructed. However, at this time, some functional groups may need to be protected and deprotected to ensure that the reaction proceeds in the desired direction. Finally, through a salt-forming reaction, the resulting product interacts with hydrochloric acid to obtain (E) -2- [3- (1-pyrrolidyl) -1-p-toluene propenyl] pyridine hydrochloride.
Second, p-toluene propene derivatives can also be used as starting materials, and they can be combined with pyridine derivatives under suitable reaction conditions, catalyzed by transition metals, and formed by carbon-carbon bonds to achieve the combination of the two. In the meantime, the reaction temperature, reaction time and ratio of reactants may need to be adjusted to optimize the reaction process. Then, a pyrrolidyl group is introduced, and this step can be achieved by nucleophilic substitution and other reactions. Finally, the target hydrochloride product is obtained through the same salt-forming step.
In addition, pyrrolidine derivatives can also be considered as starting materials to react with p-toluene haloolefin in a suitable solvent system in the presence of a phase transfer catalyst. During the reaction process, close attention should be paid to the pH and temperature of the reaction system, which have a great influence on the reaction rate and product purity. After the reaction is completed, the target product can also be obtained after the conventional operations such as separation and purification. < Br >
Synthesis of this compound requires fine regulation of various reaction conditions, and the separation and purification operations after each step are also crucial, which are related to the purity and yield of the final product.

Today I have a question, what is the market price of (E) 2- [3- (1-pyrrolidinyl) -1-p-toluphenylpropenyl] pyridine hydrochloride? This is a fine chemical, but I have checked the "Tiangong Kaiwu", which does not contain this material, it is difficult to know its price. The book "Tiangong Kaiwu" was written in the Ming Dynasty, when chemical synthesis was not as developed as it is today, and such organic compounds had not yet come out. Today is different from the past. To know its price, it is appropriate to inquire in detail at the current chemical raw material market and chemical reagent suppliers. Or you can use the online chemical trading platform to search for multiple quotations for comparison. Or contact relevant chemical companies and distributors to explore their price quotations. And the price of this compound may vary due to purity, yield, market supply and demand, etc., so it is difficult to have a fixed number. It is necessary to conduct detailed inspections to obtain a near-real price.
