The synthesis method of 2-amino-4-chloro-3-cyano-5-formylthiophene is not directly described in the ancient book "Tiangong Kaiwu", but the chemical process wisdom it contains may inspire the idea of synthesis.
To make this product, follow the conventional path of organic synthesis. First, thiophene is used as the starting material, and its active carbon-hydrogen bonds are used to introduce chlorine atoms at the fourth position through halogenation reaction. In this case, suitable halogenating reagents, such as chlorine gas or chlorine-containing compounds, can be selected to precisely locate halogenation under specific reaction conditions. < Br >
4-chlorothiophene is obtained, followed by the introduction of cyanyl at the 3rd position. This step can be achieved by nucleophilic substitution reaction, with the help of cyanophilic reagents, such as potassium cyanide, etc., with the help of catalysts. Pay attention to the control of reaction conditions to prevent side reactions.
Wait for the cyano group to be connected, and then introduce the formyl group at the 5th position. This can be achieved by means of formylation reaction, such as a mixed gas of carbon monoxide and hydrogen chloride, under a specific catalyst system.
As for the introduction of amino groups, it can be achieved by aminolysis after the previous reaction step. Ammonia or amine compounds are used to convert the corresponding groups into amino groups under suitable solvents and temperatures.
Each step of the reaction requires precise control of the reaction conditions, such as temperature, pressure, reaction time, and reagent dosage, in order to achieve high yield and high purity. And after each step of the reaction, the product is purified by suitable separation and purification means, such as distillation, extraction, recrystallization, etc., which lays a good foundation for subsequent reactions. In this way, 2-amino-4-chloro-3-cyano-5-formylthiophene can be successfully synthesized.

2-Amino-4-chloro-3-cyano-5-formylthiophene is one of the organic compounds. Its physical properties are quite important and are related to many chemical and industrial uses.
When it comes to appearance, this substance is often in a crystalline state, and the crystals are regular and have a certain geometric shape, which is quite orderly and beautiful. This is because its molecules are arranged in an orderly manner and interact stably, so this shape is formed.
In terms of color state, it is usually white or almost white. This pure color implies that it has high chemical purity and contains few impurities. The white color also reflects the regularity and purity of its molecular structure, without too many complex chromophore groups.
Determination of melting point is crucial to determine its purity and stability. Its melting point is in a specific temperature range, which is the key node for molecules to break free from lattice constraints and change from solid to liquid. Accurate determination of melting point can provide a strong basis for quality control and identification.
Solubility is also an important property. In common organic solvents, it shows different solubility characteristics. In some polar organic solvents, such as ethanol and acetone, it has certain solubility. Due to the presence of polar groups in the molecule, it can form interactions with polar solvent molecules, such as hydrogen bonds, dipole-dipole interactions, etc., to promote dissolution. In non-polar solvents, the solubility is poor, and the interaction between the molecule and the non-polar solvent is weak.
Furthermore, the density of this substance also has its specific value. The density reflects the degree of close packing of molecules, which is related to the size, shape and interaction of molecules. The appropriate density has a great impact on the mixing and separation effect of materials in specific application scenarios, such as in liquid phase reaction or separation process.
The above physical properties are related to each other and together describe the physical properties of 2-amino-4-chloro-3-cyano-5-formylthiophene, which lays the foundation for its application in chemical synthesis, drug development, materials science and other fields.

2-Amino-4-chloro-3-cyano-5-formylthiophene, an organic compound with unique chemical properties, is widely used in the field of organic synthesis.
In terms of its reactivity, its molecular structure contains many functional groups such as amino, chlorine atoms, cyano and formyl groups, so it is chemically active. Amino groups are nucleophilic and can participate in many nucleophilic substitution reactions. For example, they can react with halogenated hydrocarbons to form new carbon-nitrogen bonds, thereby constructing more complex organic molecular structures. As a good leaving group, the chlorine atom is prone to substitution reactions in the presence of nucleophiles. For example, when reacting with sodium alcohol, the chlorine atom can be replaced by alkoxy groups to form corresponding ether compounds. The cyano group is also an important functional group, and it can undergo a variety of conversion reactions. For example, hydrolysis under acidic or alkaline conditions can be converted into carboxyl groups; or by reduction, it can be converted into aminomethyl groups. The reactivity of the
formyl group cannot be underestimated. It can participate in condensation reactions, such as condensation with amine compounds, to form Schiff bases. And the formyl group can be reduced to alcohol hydroxyl groups, and this conversion can be achieved by using suitable reducing agents, such as sodium borohydride. Due to its rich functional groups, this compound has great potential in building complex organic molecular structures, providing a variety of reaction paths and possibilities for organic synthetic chemistry, and has important application prospects in many fields such as medicinal chemistry and materials science.

I look at this "2 - AMINO - 4 - CHLORO - 3 - CYANO - 5 - FORMYLTHIOPHENE", which is a special chemical substance. To know its market price, it is like exploring the value of rare and exotic treasures, and it needs to be studied by many parties.
In the past, "Tiangong Kaiwu" recorded all kinds of products, all of which described their sources, production methods and uses, and the latter was valuable. The same is true for this chemical, and its price does not depend on thin air.
First, it is related to the difficulty of its preparation. If the preparation method is cumbersome, requires many rare raw materials, and goes through many complex processes, such as ancient alchemy silver, its price will be high. On the contrary, if the preparation is relatively simple, the raw materials are easy to obtain, and the price may be slightly easier.
Second, the amount of market demand is also the key. If this substance is in strong demand in the fields of medicine, chemical industry, etc., just like rice is used for people's livelihood, everyone is competing to buy it, and its price will rise. If there is little demand, few people will ask for it, and the price will not be high.
Third, the supply situation has a great impact. If the supply is sufficient, such as water from a river, the price may stabilize. If the supply is scarce, such as the rare treasure in the mountains, the price will be high if there is occasional income.
However, I have searched all over the ancient books, but I have not obtained the exact price of "2 - AMINO - 4 - CHLORO - 3 - CYANO - 5 - FORMYLTHIOPHENE". Due to the fickle market, prices change from time to time depending on factors such as supply and demand, preparation costs, etc. To know the exact current price, you need to ask a merchant specializing in chemical reagents, or inquire about the latest chemical market conditions to know the exact price.
