What is the preparation method of 2- [4- (2-cyanoethylthiomethyl) thiazolyl] guanidine
To prepare 2 - [4 - (2 - cyanoethyl thiomethyl) ] piperazine, the preparation method is as follows:
First take an appropriate amount of raw materials, take cyanoethanol and sodium sulfide as the starting reactants, and control the appropriate temperature and pressure conditions in a specific reaction vessel to make the two react. The hydroxyl group in cyanoethanol is active, and sodium sulfide is nucleophilic. The two interact, and the hydroxyl group is replaced by sulfur ions to form sodium cyanoethyl mercaptan. This step requires fine control of the reaction time. If the reaction time is insufficient, the reaction will be incomplete, and if it is too long, it may trigger side reactions and affect the purity of the product.
Then, the resulting sodium cyanoethyl mercaptan is reacted with an appropriate halogenated methane. The halogen atom of halogenated methane is highly active, and it is easy to undergo nucleophilic substitution reaction with the sulfur atom in sodium cyanoethyl mercaptan to form 2-cyanoethyl thiomethyl compound. This step is crucial for the selection of the reaction solvent, and a solvent with suitable polarity needs to be selected to promote the smooth progress of the reaction.
Next, the obtained 2-cyanoethyl thiomethyl compound is condensed with piperazine. Piperazine has a diamino structure, in which one amino group reacts with the reactive group in the 2-cyanoethyl thiomethyl compound to form a carbon-nitrogen bond, thereby forming the basic skeleton of the target product 2- [4- (2-cyanoethyl thiomethyl) ] piperazine. This condensation reaction needs to be carried out in a basic catalytic environment to enhance the nucleophilicity of piperazine amino groups and speed up the reaction rate. At the same time, the reaction process should be closely monitored, and the reaction should be tracked by thin-layer chromatography and other means. After the reaction is complete, the post-treatment operation is carried out.
After the treatment process, the reaction mixture is extracted with a suitable organic solvent to separate the target product from the impurities. Then the extraction solution is distilled, and the solvent is evaporated according to the difference between the boiling point of the target product and the solvent to obtain the crude product. Then the purity of the product is further improved by refining methods such as recrystallization to obtain the finished product of 2- [4- (2-cyanoethylthiomethyl) ] piperazine that meets the requirements.
What are the physical properties of 2- [4- (2-cyanoethylthiomethyl) thiazolyl] guanidine
This is a question about the structural properties of chemical substances. 2- [4- (2-hydroxyethyl sulfone sulfate ethyl) yl] compound, which has several unique physical properties.
This compound contains specific functional groups, which have a significant impact on its physical properties. In terms of solubility, because it contains sulfone groups, sulfate groups and other groups with certain hydrophilicity, it may exhibit good solubility in polar solvents. If it is in water or has a certain solubility, it can partially dissolve to form a uniform dispersion system. This is because the interaction between polar groups and water molecules can form hydrogen bonds and other interactions to help them disperse in water.
In terms of melting point, the compound has complex intermolecular forces, such as sulfone groups and sulfate groups, which cause strong electrostatic interactions and van der Waals forces between molecules, which usually cause its melting point to be relatively high. To make the substance change from a solid state to a liquid state, more energy needs to be provided to overcome the intermolecular forces, so the melting point may be in a higher temperature range.
Appearance, in view of its chemical structure characteristics, if there is no special impurity or crystal form influence, or it appears as a white crystalline powder. This is due to the regular arrangement of molecules, uniform light scattering when irradiated, and then a white appearance. And the powder form is also related to the molecular aggregation state and preparation process. Under conventional preparation conditions, molecules tend to form fine particle aggregation and appear powdery.
The physical properties of this compound are determined by the interaction of functional groups in its chemical structure, which is of great significance for its application in chemical engineering, materials and other fields. Understanding these properties is helpful for rational selection of application scenarios and processing methods.

Cyanoethyl thiomethyl contains a cyanide group (-CN) and a thioether bond (-S-). Cyanyl has high reactivity. Due to the strong nitrogen electronegativity in the carbon-nitrogen triple bond, the electron cloud between carbon and nitrogen is biased towards nitrogen, which makes the carbon atom partially positively charged and vulnerable to attack by nucleophiles. In common nucleophilic substitution reactions, the cyanyl group can be replaced by other nucleophilic groups to derive a variety of compounds. This property is used in organic synthesis to construct nitrogen-containing complex structures.
In the thioether bond, the sulfur atom has two pairs of solitary pairs of electrons, which can be used as electron donor to participate in coordination chemistry related reactions. And the thioether bond can be oxidized to sulfoxide (-S (= O) -) or sulfone (-S (= O) -2 -) under specific conditions to realize the conversion of functional groups and enrich the chemical properties and applications of compounds.

If the supply of raw materials is abundant and the price is low, the product price may stabilize.
Second, the complexity of the production process has a great impact. If the production process requires a multi-step reaction, and the reaction conditions such as temperature, pressure, catalyst, etc. are strict, the difficulty and cost of production will increase, and the price will rise. On the contrary, if the process is simple and efficient, the cost will be reduced, and the price may be close to the people.
Third, the market supply and demand relationship is the core element. If the market demand for this compound is strong, but the supply is limited, as if it is rare and expensive, the price will rise. On the contrary, if the supply exceeds the demand, the merchant may reduce the price for promotion.
Fourth, the manufacturer's brand and product quality also have an impact. Well-known manufacturers pay attention to quality control, product purity and stability are high, and the price may be relatively high.
However, after searching all kinds of market information, the exact price of this specific substance could not be obtained. Due to the rapidly changing market, and the price differences between different manufacturers and products with different purity specifications are quite large. To know the exact price, you need to consult the relevant chemical product suppliers, or check the recent quotations on the chemical product trading platform in detail to obtain more accurate price information.
