The synthesis method of 2% 2C4-diethyl-1H-pyrrole-2% 2C4-dicarboxylic anhydride has been around for a long time, and has been evolving over time.
In the past, the initial method may follow the derivation path of natural products. In nature, some substances containing pyrrole structure may be delicately transformed to obtain this target product. At that time, it was mainly due to mild reaction conditions, such as weak base catalysis, at a suitable temperature, to slowly react the raw material containing a specific functional group. However, this method, the raw material is rare and the yield is quite low, and it often takes a lot of time and energy to obtain a little product.
And chemical technology is gradually refined, and organic synthesis is flourishing. There are halogenated hydrocarbons and compounds containing pyrrole structures as the beginning, and ethyl is introduced through nucleophilic substitution reaction. Then, with a strong oxidant, in an appropriate solvent, the pyrrole ring is oxidized to form an anhydride. Although this way has improved compared with the natural derivation method, the strong oxidation of the oxidant often causes a lot of side reactions, and the purity of the product is worrying. Separation and purification are also very difficult.
In today's world, science is prosperous, and new technologies and new methods emerge one after another. There are transition metal catalysis methods, which are known for their high efficiency and accuracy. Select a specific transition metal catalyst, ligand coordination, under mild conditions, the raw materials are precisely coupled to form the desired pyrrole structure, and then through ingenious acylation reaction, the dicarboxylic anhydride is obtained. This method not only greatly improves the yield, but also has few side reactions and high product purity, which brings many conveniences to industrial production and academic research. There is also a microwave-assisted synthesis method, which uses the high-frequency vibration of microwaves to accelerate the molecular movement and surge the reaction rate. Satisfactory results can be obtained in a short time, which is also the best way to synthesize this compound.

2% 2C4-diethyl-1H-pyrrole-2% 2C4-dicarboxylic anhydride, which has specific properties and has various physical and chemical properties.
In terms of its physical properties, under room temperature, it is mostly solid or crystalline powder. The quality is uniform, and the color state is often white or nearly white. It is slightly shiny under sunlight, like fine snow. Its melting point is quite critical, about a certain temperature range. This property is an important basis for identification and purification. And in different solvents, the solubility varies significantly. In some organic solvents, such as alcohols and ethers, it can be moderately dissolved. However, in water, the solubility is very small, just like oil dripping into water, and it is difficult to melt. This is due to the dominance of hydrophobic groups in the molecular structure.
As for the chemical properties, the structure of pyrrole ring and dicarboxylic acid anhydride in its structure gives unique reactivity. Pyrrole ring is aromatic and can participate in electrophilic substitution reactions, such as halogenation, nitrification, etc. The dicarboxylic acid anhydride part is easily hydrolyzed in water, just like ice and snow in warm sun, gradually melts into dicarboxylic acid. This hydrolysis reaction occurs in acid-base environments at different rates, and can be catalyzed by acids or bases. At the same time, dicarboxylic anhydride can undergo alcoholysis reaction with alcohols to form semi-esters, which are like tenon-mortise fit to construct new compounds. And this substance also has a specific response to oxidants and reducing agents. Under suitable conditions, it can undergo oxidation or reduction changes, and the structure and properties will be converted accordingly, just like phoenix nirvana, rebirth of new substances.

Your inquiry is about the price range of 2,4-diethyl-1H-pyrrole-2,4-dicarboxylic anhydride in the market. However, it is difficult to determine the price of this chemical. The price often varies due to various reasons, such as the quality, the situation of supply and demand, the distance of production sources, and the number of transactions.
If the quality is high and the market demand exceeds the supply, the price may be high; conversely, if the quality is mediocre and the supply exceeds the demand, the price may be lower. If the origin is close and the transportation is convenient, the price may be better; if the bulk transaction is large, the price may also be favorable.
As far as I know, the price of this product in the market now ranges from tens of yuan to hundreds of yuan per gram. However, this is only a rough estimate, not an exact number. To know the true price, you can consult Jia, a chemical raw material supplier, or visit the chemical product trading platform to observe the fluctuation of its price in detail, and then you can get an accurate number. You must not just follow my general words, you must personally investigate, in order to obtain the truth.

2% 2C4-diethyl-1H-pyrrole-2% 2C4-dicarboxylic anhydride is a special organic compound. Its storage conditions are related to the maintenance of its chemical properties and the effectiveness of subsequent use, which cannot be ignored.
This compound should be stored in a cool, dry and well-ventilated place. Cover a cool environment to slow down the rate of chemical reaction caused by excessive temperature, and do not cause decomposition or deterioration due to heat. Drying conditions are also critical. If the environment is humid, water vapor will easily interact with it, causing structural changes and losing its inherent nature. Well ventilated, it can disperse harmful gases that may be caused by the micro-volatilization of the compound in time to ensure the safety of the storage environment.
Furthermore, keep away from fire and heat sources. Fire and heat can cause violent reactions of this compound, or even risk combustion and explosion. And should be stored separately from oxidants, acids, bases, etc., to avoid dangerous chemical reactions with each other. Because its chemical structure contains specific functional groups, it is easy to change when encountering substances of different chemical properties.
When storing, the packaging must also be well sealed. One is to prevent it from excessive contact with outside air and oxidation and other reactions; the other is to avoid volatilization loss and ensure its content and purity. In summary, 2% 2C4-diethyl-1H-pyrrole-2% 2C4-dicarboxylic anhydride can be stored under the above conditions to maintain its chemical stability for future use.
