To prepare 3,6-bis (5-bromopyrimidine-2-yl) -2,5-bis (2-aminododecyl) pyrrolido [3,4-c] pyrrole-1,4 (2H, 5H) -dione, you can follow the following ancient method.
First take an appropriate amount of 5-bromopyrimidine-2-based related reagents, add specific catalysts and solvents to a suitable reaction vessel, create a mild reaction environment, so that it can fully react to obtain an intermediate product containing 5-bromopyrimidine-2-yl. This process requires careful temperature control and observation of the reaction process to ensure that the reaction is complete.
At the same time, the related raw materials of 2-aminododecyl are also treated. It is placed in another reaction system, and the corresponding reactants and additives are added. After a series of reactions, an intermediate product containing 2-aminododecyl is obtained.
Then, these two carefully prepared intermediate products are poured into the same reactor in a specific ratio, added with a suitable coupling reagent, heated to a suitable temperature, and continuously stirred to make the coupling reaction occur. During the reaction, pay close attention to the changes in the system and adjust the reaction conditions in a timely manner.
After the reaction is completed, the product is purified by conventional separation and purification methods, such as column chromatography, recrystallization, etc., to remove impurities, and finally obtain a pure 3,6-bis (5-bromopyrimidine-2-yl) -2,5-bis (2-aminododecyl) pyrrole [3,4-c] pyrrole-1,4 (2H, 5H) -dione.

At the time of the publication of "Tiangong Kaiwu", there was no knowledge and record of its physical properties. However, with today's chemical knowledge, its physical properties can be described as follows:
Usually, such organic compounds containing complex structures are mostly in a solid state. Due to the existence of various interactions between molecules, such as van der Waals forces, hydrogen bonds, etc., their molecules are arranged in an orderly manner to form a stable solid-state structure.
In terms of solubility, the molecule contains polar cyano, amino and other groups, which may have some solubility in polar solvents (such as water, alcohols, etc.), but because the molecule as a whole is large and contains long-chain alkyl and other non-polar parts, its solubility in water may be limited, and in some organic solvents (such as dichloromethane, N, N-dimethylformamide, etc.) The solubility may be better.
Melting point is also an important physical property. Due to the complex molecular structure and diverse interactions, its melting point is relatively high. Strong interactions between molecules require high energy to destroy the lattice structure and transform the substance from a solid state to a liquid state.
In terms of color, this type of compound may be light yellow to yellow due to its conjugated system or a certain color. The conjugated system can absorb visible light of a specific wavelength, resulting in its color.
In terms of crystal forms, during the crystallization process, molecules will be arranged according to specific rules to form crystals. Different crystallization conditions (such as temperature, solvent, etc.) or different crystal forms may be produced. The physical properties of this compound may be different in physical properties (such as melting point, solubility, etc.).
The physical properties of this compound are determined by its unique molecular structure. The interaction of different structural units endows it with various properties, which may have potential application value in materials science, medicinal chemistry and other fields.

What you said is about the market price of "3,6-bis (5-cyanoamyl-2-yl) -2,5-bis (2-aminododecyl) pyrrolio [3,4-c] pyrrole-1,4 (2H, 5H) -dione". However, this is not a common product that I am familiar with, or a special compound used in specific fields such as chemical research and pharmaceutical research and development.
The price of such compounds often varies due to multiple factors. First, the difficulty of preparation is the key. If its synthesis requires complicated steps, special raw materials or harsh reaction conditions, the cost will be high, and the price will also rise. For example, rare metal catalysts or multi-step precision reactions are required, which will greatly increase the production cost.
Second, the purity requirements have a significant impact. High purity is often used in high-end scientific research or pharmaceutical production, and the preparation is more difficult, and the price is much higher than that of low purity. If used in pharmaceutical active ingredient research, the purity requirements are almost strict, and the price is naturally high.
Third, the market supply and demand relationship also affects the price. If there is a large increase in demand for scientific research projects or industrial production at a certain time, and the supply is limited, the price will rise; conversely, if the supply exceeds the demand, the price will fall.
However, it is difficult for me to determine the specific price. If you want to know, you can consult professional chemical reagent suppliers, such as Sinopharm Group Chemical Reagent Co., Ltd., or find them on professional chemical trading platforms, or communicate with chemical experts from relevant scientific research institutions and enterprises. They may be able to provide more accurate prices based on current market conditions.
