2-%28Cyanosulfanyl%29Guanidine, that is 2- (cyanothioalkyl) guanidine, the physical properties of this substance, let me explain in detail.
Looking at its appearance, it is often white to white powder. The texture of the powder is fine, like the first fall of new snow in winter, uniform and loose, without obvious agglomeration.
In terms of its solubility, in polar solvents, there is a certain degree of solubility. For example, in water, it is slightly soluble. Water molecules interact with 2- (cyanothioalkyl) guanidine molecules, and some molecules can be dispersed between water bodies. Although the amount of solubility is limited, it is enough to show its affinity with polar solvents. In common organic solvents such as ethanol, the degree of solubility is also different. Compared with water, it may have a better solubility state, but it cannot be miscible arbitrarily and follows a specific dissolution law.
When it comes to the melting point, it can reach a certain temperature value after rigorous measurement. When the external temperature gradually rises to a specific melting point range, 2- (cyanothioalkyl) guanidine changes from solid to liquid. This melting point characteristic is just like the inherent identification of the substance, and it is a key physical basis in the identification and purification process.
Again, its density, although not very easy to perceive, can be obtained under precise measurement. Exact density data. Its density reflects the degree of closeness of the arrangement between molecules. Compared with similar substances, it may have a unique value. This value has reference value that cannot be ignored for chemical production, preparation and other aspects.
As for stability, 2- (cyanothioalkyl) guanidine can maintain a relatively stable state at room temperature and pressure without special chemical environmental interference. However, in case of extreme conditions such as high temperature, strong acid, and strong alkali, its structure may change, and its physical properties will also change. Therefore, when storing and using, it is necessary to pay attention to the impact of environmental factors on it.

2-%28Cyanosulfanyl%29Guanidine, the Chinese name may be 2 - (cyanothioyl) guanidine. The chemical properties of this substance are related to its stability, which is of great concern to many people.
To discuss the stability, it is necessary to analyze its structure. In 2 - (cyanothioyl) guanidine, the cyanothiogroup is connected to the guanidine group. Cyanothiogroups have certain electronegativity differences, and the combination of sulfur and cyanogroups makes the distribution of electron clouds unique. The guanidine group is a strong basic group containing nitrogen, with a conjugated structure, which can stabilize the charge.
From the perspective of reactivity, the sulfur atom of the cyanothiogroup is rich in outer electrons and has a nucleophilic tendency, which can participate in However, the presence of guanidine groups may affect their electron clouds, causing changes in their nucleophilic activity. If there are electrophilic reagents in the environment, cyanothio groups may act with them first, which may affect their stability.
Temperature is also a key factor. When heated, the vibration of the chemical bond of 2 - (cyanothio) guanidine intensifies. If it reaches a certain energy, it may cause the bond to break. The bond between cyanothio groups and guanidine groups may be cracked due to excessive energy, causing structural changes and impaired stability.
Its stability also varies in different solvents. In polar solvents, due to the interaction between the solvent and the solute, or the change of molecular charge distribution, the internal force of 2 - (cyanothio) guanidine is affected. If the solvent interacts with cyanothio or guanidine to form hydrogen bonds, or changes its activity, the stability is affected.
Overall, the stability of 2 - (cyanothio) guanidine is not static, and it is affected by many factors such as structure, reactivity, temperature, and solvent. Therefore, its stability needs to be judged according to specific conditions. Under specific circumstances, it may have relative stability. However, if the conditions change, its stability will also change accordingly.

To make 2 - (cyanothioyl) guanidine, there are various methods, and the number of times is now.
First, guanidine thiocyanate is used as the starting material. Take an appropriate amount of guanidine thiocyanate, place it in a suitable reaction kettle, add an appropriate amount of strong base, such as sodium hydroxide or potassium hydroxide, use alcohols as solvents, such as ethanol or methanol, control the temperature in a moderate range, about 50 to 80 degrees Celsius, and stir the reaction number. During this process, the strong base prompts the intramolecular rearrangement of guanidine thiocyanate, which in turn generates 2 - (cyanothioyl) guanidine. After the reaction is completed, the excess base is neutralized with an appropriate acid, and then the pure product can be obtained by reduced pressure distillation and recrystalli
Second, cyanamide and thiourea are used as raw materials. First, cyanamide and thiourea are dissolved in an appropriate ratio, usually 1:1.2 to 1:1.5, in an organic solvent such as dimethylformamide (DMF) or dimethyl sulfoxide (DMSO). Add an appropriate amount of catalyst, such as an organic base or a metal salt, and heat and stir the reaction at 70 to 90 degrees Celsius. Cyanamide and thiourea are condensed to form 2- (cyanothio) guanidine. After the reaction, the product is purified through filtration, washing, drying and other steps.
Third, halogenated acetonitrile and thiourea are used as starting materials. The halogenated acetonitrile, such as bromoacetonitrile or chloroacetonitrile, is reacted with thiourea in an alkaline environment. The halogenated acetonitrile is slowly dropped into a mixed solution containing thiourea and a base. The base can be selected from sodium carbonate or potassium carbonate, and the solvent can be selected from a mixture of water and organic solvents, such as ethanol-water system. The reaction temperature is maintained at 30 to 60 degrees Celsius. After a period of reaction, a mixed solution containing 2- (cyanothio) guanidine is obtained. Subsequent operations such as extraction, distillation, and crystallization are carried out to separate pure 2- (cyanothio) guanidine.
All kinds of production methods, each with its own advantages and disadvantages, need to be based on the actual situation, such as the availability of raw materials, cost, product purity requirements, etc., to choose the right one to obtain the required 2 - (cyanothio) guanidine.

2-% (Cyanosulfanyl) Guanidine is a unique chemical substance. When using it, all kinds of precautions must not be ignored.
Those who bear the brunt, safety protection is of paramount importance. This substance may be toxic and irritating to a certain extent, so when operating, complete protective equipment must be worn, such as protective clothing, gloves, goggles, etc., to prevent it from contacting the skin, eyes, etc., to avoid harm. And the operation should be carried out in a well-ventilated place. If it is in a closed space, its volatile gas may cause inhalation and damage the respiratory organs.
Furthermore, the method of storage should also be paid attention to. It should be placed in a cool, dry and well-ventilated place, away from fire and heat sources. Due to its chemical properties, or reactions with other substances, it needs to be stored separately from oxidants, acids, bases, etc., and must not be mixed to prevent accidental chemical reactions from occurring and causing danger.
During use, the precise operating standards must not be ignored. Use strictly according to the established process and dosage, and cannot be changed without authorization. If you need to dissolve this substance, choose a suitable solvent, and pay attention to the dissolution conditions, such as temperature, stirring rate, etc., to ensure that it is evenly dispersed and plays its due role. At the same time, the use of utensils must be clean to avoid impurities from mixing and affecting their performance.
In addition, after use, the residue and discarded utensils should be properly disposed of in accordance with relevant regulations. Do not discard at will, so as not to pollute the environment and harm the ecology. Proper waste disposal procedures need to be followed to ensure environmental safety.
In short, throughout the use of 2-% (Cyanosulfanyl) Guanidine, safety awareness, standardized operation and proper disposal are all crucial, and no slack is allowed, so as to ensure smooth and safe use.
