To make 1%2C1%27-%28methylenedi-1%2C4-phenylene%29bis-1H-pyrrole-2%2C5-dione, the method is as follows:
First take an appropriate amount of 1,4-benzodiformaldehyde and pyrrole as raw materials, and the amount of the two should be matched according to a specific ratio. In an appropriate reaction vessel, add an appropriate amount of organic solvent, such as dichloromethane or chloroform, so that the raw materials can be evenly dispersed and fully contacted.
In the reaction system, an appropriate amount of catalyst, such as p-toluenesulfonic acid, needs to be added. The function of the catalyst is to accelerate the reaction process and promote the reaction to proceed in the direction of generating the target product.
After the reaction vessel is closed, the reaction is placed in an appropriate temperature environment. This temperature needs to be precisely controlled. Generally speaking, it can be maintained between room temperature and 50 degrees Celsius, and fine-tuned according to the specific situation. During the reaction process, it is necessary to continuously stir to allow the reactants to be fully mixed to ensure the uniformity of the reaction.
After a certain period of time, use thin-layer chromatography or other suitable analytical methods to monitor the reaction process. The reaction can be terminated when the raw materials are exhausted and the target product formation amount reaches the expected.
Then, the reaction mixture is treated. The organic phase is extracted with a suitable solvent, and then dried with anhydrous sodium sulfate to remove the moisture.
Finally, the product is purified by column chromatography or recrystallization. During column chromatography, suitable stationary and mobile phases are selected to effectively separate impurities from the target product; recrystallization requires the selection of suitable solvents to crystallize the target product at a suitable temperature, so as to obtain high-purity 1%2C1%27-%28methylenedi-1%2C4-phenylene%29bis-1H-pyrrole-2%2C5-dione.

I think what you are asking is about the price range of "1,1 '- (methylenedi-1,4-phenylene) bis-1H-pyrrole-2,5-dione" in the market. However, the price range of this chemical product is difficult to say in a word. The price often changes due to many reasons.
First, the purity of this compound has a great impact on the price. If the purity is extremely high, it is almost perfect, and it is suitable for high-end scientific research and special industrial processes, the price will be high. On the contrary, if the purity is slightly lower, it is only used for ordinary experiments or general production, and the price is slightly lower.
Second, the supply and demand is also the key. If there are many people in the market, but there are few products, and the supply is in short supply, the price will increase. If there is overproduction and little demand, the price may fall.
Third, the difficulty of production and the cost of raw materials all affect the price. If the preparation of this compound requires complicated processes and expensive raw materials, the cost will be high and the price will also be high.
Fourth, the price will be different in different places due to different economic levels, tax policies, etc. In prosperous cities, due to high operating costs, the price may be higher than in remote places.
However, I have searched all over the place, but I have not been able to determine the specific price range. For details, you can consult the chemical raw material market, relevant chemical trading platforms, or contact manufacturers and distributors to get accurate prices.
