2-Thiophene acetonitrile is also an organic compound. It has specific physical properties and is listed below.
Looking at its appearance, under room temperature and pressure, 2-thiophene acetonitrile is a colorless to light yellow liquid. When it is pure, this state is stable and visible. Its odor is specific, and ordinary people can smell it, and they can feel a special smell. Although it is not pungent or intolerable, it is also unique. This odor characteristic can be helpful for preliminary identification.
When it comes to the melting point, the melting point of 2-thiophene acetonitrile is quite low, about -20 ° C, which indicates that it can still maintain a liquid state in a relatively low temperature environment. The boiling point is higher, about 256-258 ° C. The higher boiling point is due to the relatively strong intermolecular forces, which require higher energy to transform it from liquid to gaseous.
As for the density, the density of 2-thiophene acetonitrile is slightly higher than that of water, about 1.19g/cm ³. This property causes it to sink to the bottom if mixed with water, which is critical during separation operations.
In terms of solubility, 2-thiophene acetonitrile has good solubility in organic solvents, such as ethanol, ether, acetone, and other common organic solvents. However, in water, its solubility is very small, because the molecular polarity of the compound is quite different from that of water, and follows the principle of "similar miscibility".
In addition, the vapor pressure of 2-thiophene acetonitrile is low, and the volatilization rate is slow at room temperature. This property makes it relatively stable during storage and use, and it is not easy to be lost due to rapid volatilization. And because of the existence of thiophene ring and cyanyl group in its chemical structure, it gives it a certain chemical activity. In the field of organic synthesis, it is often an important raw material, participating in a variety of chemical reactions and showing unique chemical charm.

The synthesis method of 2-thiophene acetonitrile has been known for a long time. The first is to use thiophene as the starting material and acylate it to obtain a thiophene acetyl compound. This acylation reaction can be carried out under specific reaction conditions in the presence of suitable catalysts. After acylation, the resulting product is then cyanized to introduce a cyanyl group to obtain 2-thiophene acetonitrile. The cyanidation step, or the use of cyanide reagents, such as sodium cyanide, potassium cyanide, etc., with the help of a phase transfer catalyst, makes the reaction occur smoothly.
The second method also uses thiophene derivatives as the starting material. First, the specific position of the thiophene derivative is functionalized, such as the introduction of halogen atoms. Then, through the nucleophilic substitution reaction, the halogen atom is replaced by a cyanide-containing reagent, such as a cyanide salt, to obtain the target product 2-thiophene acetonitrile. This nucleophilic substitution reaction requires attention to factors such as the reaction solvent, temperature and the proportion of reactants to promote the efficient progress of the reaction.
Furthermore, there are still those who start with other related compounds and construct thiophene rings through multi-step reactions and introduce acetonitrile groups. Although these methods are slightly complicated, they may have unique advantages in specific situations. In the reaction process, the control of the conditions of each step of the reaction, the separation and purification of the intermediate are all key points, which are related to the purity and yield of the final product.

2-Thiophene acetonitrile is an important raw material for organic synthesis. During storage and transportation, many matters must be paid attention to.
First talk about storage. This substance should be placed in a cool and ventilated warehouse. Because of the cool and ventilated place, it can avoid danger caused by high temperature. Under high temperature, 2-thiophene acetonitrile may chemically react, causing its properties to change, and even the risk of fire and explosion. The temperature of the warehouse should be controlled in an appropriate range, not too high. And it must be kept away from fire and heat sources, both of which are the root causes of danger.
Furthermore, it should be stored separately from oxidizing agents, acids, bases, etc., and should not be mixed. Due to the fact that 2-thiophene acetonitrile and the above-mentioned substances are prone to chemical reactions, or cause serious consequences such as combustion and explosion. The storage area should also be equipped with suitable materials to contain the leakage, so as to prevent accidental leakage, and it can be properly handled in time to avoid greater disasters.
As for transportation, be sure to ensure that the packaging is complete and safely loaded before transportation. If the packaging is damaged, 2-thiophene acetonitrile may leak out, which not only wastes raw materials, but also may endanger the transportation environment and personnel safety. During transportation, ensure that the container does not leak, collapse, fall, or damage. When driving, you need to protect yourself from sun exposure, rain, and high temperature. Summer transportation, you should pay special attention to this point, and choose a cool time when necessary. During transportation, you should also follow the prescribed route and avoid stopping in densely populated areas and residential areas to avoid accidents that could cause major casualties.

2-Thiophene acetonitrile, as well as organic compounds, is widely used in chemical, pharmaceutical and other fields. Its market price trend is often influenced by multiple factors.
First, the price of raw materials is very critical. The synthesis of 2-thiophene acetonitrile often requires specific raw materials. If the raw materials are scarce, or the supply is suddenly reduced due to natural disasters or geopolitics in the place of origin, the price will rise; on the contrary, if the supply of raw materials is abundant, the price may stabilize or even decline.
Second, the market supply and demand trend has a great impact. If the pharmaceutical industry is enthusiastic about the research and development of new drugs containing 2-thiophene acetonitrile, the demand will increase sharply, and the production capacity will be difficult for a while, the price will tend to rise; if the market demand is weak and the manufacturer has excess capacity, the price may fall in order to sell inventory.
Furthermore, policies and regulations also play a role. Environmental protection policies are stricter, and some non-compliant small factories may be shut down, resulting in a decrease in overall production capacity, and prices may be driven up; on the contrary, policies to encourage the development of related industries may introduce new manufacturers to the market and increase production capacity, which will put downward pressure on prices.
Technological innovation cannot be ignored. If a new synthetic process comes out, it can reduce costs and increase production capacity, and the price of 2-thiophene acetonitrile may fall due to cost reduction.
In summary, the market price trend of 2-thiophene acetonitrile is complex and changeable due to factors such as raw material supply, market supply and demand, policies and regulations, and technological progress. The industry must pay close attention to it to cope with market changes.
