The reaction conditions are quite critical, and the temperature needs to be precisely controlled. At low temperatures, the reaction rate may be slow, making it difficult to achieve the expected conversion; at high temperatures, side reactions may occur frequently, and the purity of the product will be damaged. Usually heated moderately, such as between 50 and 100 degrees Celsius, fine-tuned according to the activity of the reactants and the properties of the solvent.
The solvents used are also exquisite. Polar organic solvents such as dimethylformamide (DMF) or dimethyl sulfoxide (DMSO) can improve the solubility and ionic activity of the reactants, which is conducive to the reaction.
Furthermore, the choice of catalyst also has a significant impact. Base catalysts, such as potassium carbonate and sodium carbonate, can promote the formation of nucleophiles and accelerate the reaction process. In the synthesis of

2-Amino-3,5-dicyano-4-methylthiophene is an organic compound with unique physical properties. Looking at its properties, it is mostly solid under normal conditions. Due to the strong interactions between molecules, such as van der Waals forces and hydrogen bonds, the molecules are arranged in an orderly manner and stabilized into a solid state.
When it comes to the melting point, the melting point of this substance is quite high. Because the cyano group and the amino group in the molecule can form many hydrogen bonds, and the conjugate system of the thiophene ring enhances the intermolecular force, more energy is required to make the molecule break free from the lattice binding and transform into a liquid state, so the melting point is in a relatively high range.
In terms of solubility, it exhibits a certain solubility in common organic solvents such as dichloromethane and N, N-dimethylformamide (DMF). Methylene dichloride has moderate polarity and can interact with some polar groups of the compound; DMF can dissolve it by forming hydrogen bonds with 2-amino-3,5-dicyano-4-methylthiophene due to strong polarity. However, the solubility in water is poor. Although water has strong polarity, the hydrophobic thiophene ring and methyl part of the compound account for a large proportion, which hinders its full interaction with water molecules, resulting in insolubility in water.
In terms of stability, the chemical properties of this compound are relatively stable under normal conditions due to the existence of a conjugated system. However, cyano and amino groups have certain reactivity and can still react under specific reagents and reaction conditions. For example, amino groups can participate in nucleophilic substitution reactions, and cyano groups can undergo hydrolysis, addition and other reactions. When storing and using, care should be taken to avoid contact with substances that can initiate reactions, and choose a suitable environment to prevent unnecessary chemical reactions.

2-Amino-3,5-dicyano-4-methylthiophene, this is an organic compound. Its chemical properties are unique, and it is related to many reaction characteristics and physical properties.
In terms of its stability, under common conditions, this compound is quite stable. When encountering strong oxidizing agents or reducing agents, its structure may change. Strong oxidizing agents may cause oxidation reactions of substituents on thiophene rings, causing cyano or amino conversion. Strong reducing agents may reduce cyanos to amino or other groups. < Br >
In terms of solubility, due to its polar groups, it has a certain solubility in polar organic solvents such as dimethyl sulfoxide (DMSO) and N, N-dimethylformamide (DMF). However, in non-polar solvents such as n-hexane and benzene, the solubility is very small. This property is of great significance in its separation, purification and choice of reaction medium.
From the perspective of reactivity, amino groups can participate in nucleophilic substitution reactions. Due to the existence of lone pairs of electrons on nitrogen atoms, it has nucleophilic properties and can react with electrophilic reagents such as halogenated hydrocarbons to form new carbon-nitrogen bonds. The cyanyl group can be hydrolyzed and gradually converted into a carboxyl or amide group under acidic or basic conditions. Although the thiophene ring is aromatic and relatively stable, it can also undergo electrophilic substitution reaction under specific conditions, such as strong Lewis acid catalysis, and the reaction check point is mostly at the α-position of the thiophene ring.
2-amino-3,5-dicyano-4-methylthiophene has rich and diverse chemical properties, which lay a solid foundation for its application in organic synthesis, materials science and other fields.

I cannot confirm the market price range of 2-amino-3,5-dicyano-4-methylthiophene. The price of the market is often changed for many reasons. The abundance of its raw materials, if the raw materials for producing this substance are readily available and in sufficient quantities, the price may be inexpensive; if the raw materials are rare, the price must be high.
The simplicity of the process is also the main reason. If the method of making this substance is simple, the cost is low, and the price is low; if the process is complicated, delicate techniques and many steps are required, the cost will be high, and the price will also rise.
The state of demand and supply is related to the rise and fall of prices. If there are many seekers and few suppliers, the price will rise; if the supply exceeds the demand, the price will fall.
There are different merchants, and their pricing strategies are different, either for high profits or to expand sales, resulting in different prices.
In addition, different regions, different taxes and transportation fees also make the price different. In distant places, transportation is difficult, and the cost is high, and the price may be higher than in the vicinity.
Although I cannot determine the price range, if you want to know, you can go to the chemical raw material market, consult merchants, or check professional chemical product price information platforms, or get a more accurate price.
