2-Cyano-3-methylthiophene is one of the organic compounds. Its physical properties are particularly important and are related to the use and characteristics of this compound.
First of all, its appearance, under normal temperature and pressure, 2-cyano-3-methylthiophene is often colorless to light yellow liquid. This color state is easy to observe and identify. In chemical operations and other scenes, operators can preliminarily judge its state and purity based on its appearance.
Second, its boiling point is about a certain temperature range. Boiling point, the temperature limit for a substance to change from liquid to gas. The boiling point characteristics of 2-cyano-3-methylthiophene are of great significance in chemical processes such as distillation and separation. Knowing its boiling point can precisely adjust the temperature to achieve effective separation of this compound from other substances for the purpose of purification.
Furthermore, its melting point is also a key physical property. The melting point is the critical temperature at which a substance changes from solid to liquid. The melting point data of 2-cyano-3-methylthiophene is helpful for rational disposal according to the ambient temperature during storage and transportation, to ensure that it is in a suitable physical state, and to avoid changes in its state due to improper temperature and affect the quality.
Repeat its solubility. This compound exhibits specific solubility properties in organic solvents. For example, in common organic solvents, such as ethanol, ether, etc., it has a certain solubility. This solubility is conducive to its role as a reactant or intermediate in organic synthesis reactions. With the help of solvent properties, the smooth progress of the reaction is promoted, and the reaction efficiency and product purity are improved.
In addition, the density of 2-cyano-3-methylthiophene is also an important physical parameter. Density reflects the quality of the substance per unit volume and is indispensable in the measurement and ratio of chemical production. Accurately knowing its density can achieve precise control during feeding, mixing and other operations to ensure the stability of the production process and the uniformity of product quality.
All these physical properties are interrelated and together constitute the characteristic characterization of 2-cyano-3-methylthiophene, which plays a pivotal role in the research and application of many fields such as chemical industry and materials science.

The stability of the chemical properties of 2-cyano-3-methylthiophene is related to many aspects. This compound contains cyanyl (-CN) and methylthiophene groups. The cyanyl group has high reactivity and can participate in many reactions, such as hydrolysis to form carboxyl groups, or addition reactions with nucleophiles. Therefore, under certain conditions, due to the presence of cyanyl groups, its chemical properties are difficult to say stable.
Furthermore, the thiophene ring is aromatic, but its aromaticity is slightly weaker than that of the benzene ring. Although the methyl group at the 3-position has an effect on the distribution of the electron cloud of the thiophene ring, it does not fundamentally change the reactivity of the thiophene ring. When encountering electrophilic reagents, thiophene rings can undergo electrophilic substitution reactions, which also shows that their chemical properties are not completely stable.
If it is in a mild environment without strong nucleophiles, electrophilic reagents or special reaction conditions, 2-cyano-3-methylthiophene can still maintain a certain stability. However, in complex and changeable chemical reaction systems, due to the inherent activity of cyano and thiophene rings, its chemical properties are difficult to be stable, and it is easy to participate in various chemical reactions, resulting in changes in its own structure.

The synthesis method of 2-cyano-3-methylthiophene, although the ancient book "Tiangong Kaiwu" does not describe the synthesis method of this specific compound in detail, it can be deduced from the wisdom of the ancients and related chemical ideas.
First, it can be derived from compounds containing thiophene structure. If 3-methylthiophene is used as the starting material, a cyanide group can be added by cyanation reaction. If a suitable cyanide reagent, such as potassium cyanide (KCN), is used under appropriate reaction conditions, the cyanide group may be able to replace the hydrogen atom at a specific position on the thiophene ring, and then the target product can be synthesized. However, potassium cyanide is highly toxic, and the operation needs to be extremely cautious. Strict protection and treatment measures are required. < Br >
Second, the thiophene ring can be constructed by yourself. First, the thiophene ring is constructed by a series of reactions such as condensation and cyclization with suitable sulfur-containing and carbon-containing compounds, and methyl and cyano groups are ingeniously introduced during the cyclization process or subsequent steps. For example, the compound containing methyl and sulfur atoms and the compound containing cyanide groups and suitable functional groups are selected. Under the action of a specific catalyst, the cyclization and functional group integration are achieved through multi-step reactions, and the final product is 2-cyano-3-methylthiophene.
Third, it can also be synthesized by organometallic reagents. The organometallic reagent containing thiophene ring is reacted with the reagent containing cyanide group and methyl group. With the help of the activity and selectivity of the metal reagent, the coupling reaction between the two occurs to form the target molecule. In this process, the selection of organometallic reagents and the regulation of reaction conditions are extremely critical, which is related to the success or failure of the reaction and the purity of the product.

Looking at this question, I want to know the price of 2-cyano-3-methylthiophene in the market. However, the price of this chemical often changes due to various reasons.
First, the price varies depending on the manufacturer. The cost and process of each manufacturer are different, resulting in different pricing. Reputable manufacturers, based on high quality, have high prices; new factories are competing for the market, and the price is low.
Second, the quantity is different, and the price is also different. If the purchase volume is huge, the manufacturer often gives a discount, because it can reduce its sales cost; if the quantity is small, the price may continue as usual, and there is no preferential benefit.
Third, the price fluctuates with the change of time. The price of raw materials and the trend of supply and demand change at any time. When the price of raw materials rises, the price of this product also rises; if the supply exceeds the demand, the price will drop; if the demand exceeds the supply, the price will rise.
And although "Tiangong Kaiwu" is detailed in all process products, this chemical is a product of today, and the ancient books do not cover its price.
If you want to know the exact price today, you should consult chemical suppliers, trading platforms, or check it on the chemical trading website to get a near real-time price for business and scientific research needs.
