1,3-Dibromo-5-(2-ethylhexyl)-4H-thieno[3,4-c]pyrrole-4,6(5H)-dione

The chemical properties of this compound are that its aldehyde group is active and reactive, and can react with many nucleophiles, such as acetals with alcohols, which are often used in organic synthesis to protect the aldehyde group or to construct complex carbon skeletons.
Its pyranopyrazole ring structure endows this compound with a unique electron cloud distribution and spatial configuration, causing it to exhibit certain acidity and alkalinity under specific conditions. In alkaline media, the hydrogen atoms on the pyrazole ring can be removed to form corresponding negative ions, which can then participate in nucleophilic substitution or nucleophilic addition reactions.
Furthermore, the 2-ethylhexyl group of its side chain also affects its physical and chemical properties. This long-chain alkyl group enhances the lipid solubility of the molecule and affects its solubility and phase behavior in different solvents. In some organic reaction systems, its lipid solubility can affect the interaction between molecules, change the reaction rate and selectivity.
In addition, the diketone structural part of the compound also has unique chemical properties, and the two carbonyl groups of the diketone can cooperate to participate in the reaction, such as the condensation reaction within the molecule, forming a more complex ring structure. And the enol tautomer of diketone may also exist. Under the catalysis of acid and base, the ketone and enol tautomers can be converted into each other, and this tautomer phenomenon plays an important role in some chemical reactions and biological activities. In short, this substance exhibits rich and diverse chemical properties due to the synergistic effect of multiple structural parts, and may have potential application value in organic synthesis, medicinal chemistry and other fields.

To make diether, the following methods can be used. First, ethanol is taken, catalyzed by sulfuric acid, and heated to react. First, at 140 degrees Celsius, the ethanol molecules are dehydrated, and diether is obtained. In this reaction, sulfuric acid acts as a dehydrating agent and a catalyst to promote the interaction of ethanol molecules. The hydroxyl group of one ethanol is combined with the hydrogen of the other ethanol to form water to dehydrate, and the two ethanol groups are connected to form diether.
The reaction formula is roughly as follows:\ (2C_ {2} H_ {5} OH\ xrightarrow [140 ^ {\ circ} C] {concentrated sulfuric acid} C_ {2} H_ {5} OC_ {2} H_ {5} + H_ {2} O\).
When operating, pay attention to the concentration and dosage of sulfuric acid, and control the reaction temperature. Improper concentration of sulfuric acid or temperature deviation can cause side reactions to occur. If the temperature reaches 170 degrees Celsius, ethanol will undergo intramolecular dehydration and form ethylene instead of diether.
Furthermore, the reaction device needs to be reasonably built to ensure that the system is well sealed to avoid the escape of reactants and products, and the yield will be reduced. After the reaction, the purification step is required to obtain pure diether except for unreacted ethanol, sulfuric acid and other impurities. In this way, according to these methods, diether can be prepared.

Looking at this question, I am inquiring about the price of dinitrile in the market. However, the information presented, such as "1% 2C3-diether-5- (2-isopropyl ethyl) -4H-imidazolo [3,4-c] pyridine-4,6 (5H) -dinitrile", is a specific expression of the chemical substance, and in order to clarify its price, many situations need to be involved.
In the city, the price of chemical substances often varies with quality, purity, supply and demand, and difficulty in preparation. If the purity of this dinitrile is extremely high, it is close to the reagent grade, and it is used for scientific research, its price must be high. Due to the strict requirements for purity in scientific research, the production requires fine technology and high cost.
If the market demand for this dinitrile is strong and the supply is limited, the price will also rise. If an emerging industry suddenly flourishes, a large amount of this dinitrile is required as raw material. If the production capacity is not enough, the price will rise.
On the contrary, if the production process of this dinitrile is simple, the market supply is sufficient, and the demand is normal, its price will tend to be easy.
However, it is difficult to determine the market price based on existing information. To get an accurate price, you should consult chemical raw material suppliers, chemical product trading platforms, or refer to industry reports to get a more accurate price.
