To prepare ethyl + 5 - [bis (2 - ethoxy - 2 - oxo - ethyl) amino] - 4 - cyano - 3 - (2 - ethoxy - 2 - oxo - ethyl) thiophene - 2 - carboxylate, there are many methods, which can be selected according to factors such as required raw materials, equipment and cost.
First, it can be started by a compound containing a thiophene structure. First, take a thiophene derivative with a suitable substituent, make it react with a cyanyl-containing reagent under suitable conditions, and introduce a cyano group. If a base is used as a catalyst, the reaction is heated in an organic solvent to promote the cyanosubstituted thiophene ring atom or group at a specific position.
Then, the resulting product is condensed with a compound containing an ethoxy carbonyl group. This step may require the assistance of a condensing agent, such as dicyclohexyl carbodiimide (DCC), at mild temperatures, so that the two condensate to construct the desired ester group and amide structure.
Furthermore, you can try to modify the sulfur atom on the thiophene ring. Or choose an appropriate halogenated ethoxy carbonyl compound, react with the sulfur atom of the thiophene ring under metal catalyst or basic conditions, and introduce the (2-ethoxy-2-oxo-ethyl) group.
During the reaction process, the reaction temperature, time and the proportion of the reactants need to be carefully controlled. If the temperature is too high or the side reactions are clustered, and if it is too low, the reaction rate will be delayed. The proportion of the reactants is also critical. If the ratio is improper, or the product is impure, the yield will be affected.
After each step of the reaction, suitable separation and purification methods, such as column chromatography and recrystallization, are required to obtain the pure product. After multi-step reaction and purification, ethyl + 5 - [bis (2 - ethoxy - 2 - oxo - ethyl) amino] - 4 - cyano - 3 - (2 - ethoxy - 2 - oxo - ethyl) thiophene - 2 - carboxylate was obtained.

This is ethyl 5- [bis (2-ethoxy-2-oxyethyl) amino] -4-cyano-3- (2-ethoxy-2-oxyethyl) thiophene-2-carboxylic acid ester. Looking at this compound, its physical and chemical properties are quite elegant.
In terms of physical properties, its appearance may be solid, but the exact state depends on the specific synthesis and environmental conditions. Its melting point and boiling point are key physical parameters. The melting point reflects the temperature at which it transitions from solid to liquid, and the boiling point is related to the conditions for liquid to gas. The two are influenced by intermolecular forces. There are many polar groups in the molecule of the compound, such as cyanyl groups, ester groups, and groups containing nitrogen and oxygen, which increase the intermolecular forces, or make the melting point and boiling point at a higher level.
In terms of solubility, because the molecule contains many polar parts, it may have a certain solubility in polar solvents such as alcohols and ketones. In non-polar solvents such as alkanes, the solubility may be very small. Due to the principle of "similar compatibility", polar molecules are more likely to interact with polar solvents.
In terms of chemical properties, cyanyl groups can participate in many reactions, such as hydrolysis reactions. Under acidic or basic conditions, cyanyl groups can be converted into carboxyl groups or amide groups. The ester group is also active and can undergo hydrolysis reaction. It is hydrolyzed in acidic medium to form carboxylic acids and alcohols, and hydrolyzed more thoroughly under alkaline conditions to form carboxylic salts and alcohols. In addition, although the thiophene ring is relatively stable, it may also react under specific conditions, such as the action of strong oxidants. The electron cloud distribution on the ring is affected by the substituent group, or the reactive activity is slightly different from that of the thiophene itself. Groups containing nitrogen and oxygen atoms in the molecule can be used as nucleophiles or electrophilic reagents to participate in the reaction, and react with suitable substrates such as substitution and addition. In short, due to the diverse groups in the structure, this compound has rich physical and chemical properties and reactive activities, and may have potential uses in organic synthesis and other fields.

I look at this question and ask ethyl + 5 - [bis (2 - ethoxy - 2 - oxo - ethyl) amino] - 4 - cyano - 3 - (2 - ethoxy - 2 - oxo - ethyl) thiophene - 2 - carboxylate at the market price. However, this is a fine chemical, and its price is not constant and is affected by many factors.
First, the quantity is small. If the quantity is large, the supplier may give a discount to promote the transaction.
Second, the quality is good or bad. Those with high quality, the production process may be more complicated, the raw materials may be more sophisticated, and the price is also high. Those with slightly inferior quality, the price may be slightly lower, but it may affect the effectiveness of use.
Third, the source is different. Different manufacturers, due to differences in cost, technology, and market positioning, have different pricing. Well-known large factories, or due to the superiority of brands and after-sales, have higher prices; emerging small factories, or to expand the market, the price may be close to the people.
Fourth, the supply and demand of the city. If there are many applicants and few suppliers, the price may rise; if supply exceeds demand, the price may decline.
And the market fluctuates, raw material prices, policies and regulations, transportation costs, etc., can all change their prices. Therefore, to know the exact price, you need to consult chemical raw material suppliers, distributors, or check in detail on professional chemical trading platforms to get a more accurate price.
