2% 2C2% 27 - bis% 282 - chlorophenyl% 29 - 4% 2C4% 27% 2C5% 2C5% 27 - tetraphenyl - 2H% 2C2% 27H - 2% 2C2% 27 - biimidazole, this is an organic compound. Its physical and chemical properties are unique and valuable for investigation.
Looking at its physical properties, under normal circumstances, it may be solid and mostly powdery. Due to its molecular structure, the intermolecular forces are stable, so it can maintain a solid state. As for the color, either white or close to white light color, because there is no excessive conjugation system in the molecular structure, it is difficult to strongly absorb visible light, so it presents such light color.
In terms of solubility, this compound is highly hydrophobic due to its many phenyl groups, and its solubility in water is extremely low. However, in organic solvents, such as chloroform and dichloromethane, the solubility may be improved due to their similar phase dissolution principle. This is because the molecules of the organic solvent and the molecules of the compound can form similar intermolecular forces, such as van der Waals forces, to promote dissolution.
In terms of chemical properties, the imidazole ring in the molecule gives it a certain alkalinity, because there are lone pairs of electrons on the nitrogen atom, which can accept protons. The presence of chlorine atoms makes the compound participate in nucleophilic substitution reactions. The aromatic ring part can undergo electrophilic substitution reactions such as the Fu-Ke reaction. Due to the high density of the aromatic ring electron cloud, it is vulnerable to electrophilic attack. Furthermore, the conjugate system of the compound makes it have certain photophysical properties, or under the irradiation of specific wavelengths of light, fluorescence occurs. After the molecule absorbs light energy, the electron transitions, and then returns to the ground state to release photons.
The above is a general investigation of the physicochemical properties of this compound, and many details still need to be verified experimentally.

I see what you are asking about "2,2 '-bis (2-chlorophenyl) -4,4', 5,5 '-tetraphenyl-2H, 2'H-2,2' -biimidazole" and the market price. However, this product is not a common daily use product, and its market price is quite difficult to describe.
The price of this product is affected by multiple factors. The first one is the purity of this product. If the purity is extremely high, the process is excellent, and the preparation is difficult, the price will be high; on the contrary, if the purity is slightly lower, the price may be reduced. Secondly, the preparation cost is also the key. The price of raw materials, the equipment and labor required for the preparation process, etc., all affect the final cost, which in turn affects the selling price. Furthermore, the situation of market supply and demand should not be underestimated. If there are many people who want it, but there are few people who supply it, the price will inevitably rise; if there is an oversupply, the price may be downward.
Because I don't know the specific situation of this product in the current market, such as the number of manufacturers, the situation of industry competition, etc., it is difficult to specify its price. If you want to know more, you can ask the supplier of chemical raw materials, or look up a professional chemical product trading platform to get more accurate price information.

Although its safety and toxicity are not directly recorded in ancient books, it can be inferred as follows from a scientific perspective.
In terms of toxicity, this compound contains a chlorophenyl structure. The presence of chlorine atoms may make the substance toxic to a certain extent. Chlorophenyl is difficult to degrade in living organisms and can interact with biological macromolecules such as proteins and nucleic acids. It may interfere with the normal metabolic process of cells, such as hindering the activity of enzymes and causing physiological dysfunction of cells. Studies have shown that chlorinated organic compounds can often affect the nervous system and endocrine system of organisms. If this compound enters the human body, or is absorbed through the respiratory tract, digestive tract or skin, it accumulates in the body, damaging important organs such as liver and kidney.
In terms of safety, due to its complex structure, it is stable or high in the environment. During production and use, if it is not disposed of properly, it may be released into the environment. It remains in soil, water, or is transmitted through the food chain, causing potential harm to the ecosystem. In industrial production, strict control is required to prevent exposure of workers. Storage also needs to be cautious to avoid mixing with oxidizing and reducing substances to prevent dangerous reactions.
In summary, although ancient books do not contain, according to modern chemical knowledge, 2,2 '-bis (2-chlorophenyl) -4,4', 5,5 '-tetraphenyl-2H, 2'H-2,2' -biimidazole may have certain toxicity and environmental risks, use and disposal must be cautious to ensure safety.
