I don't know what you said about "2% 2C2% 27 - bis% 282 - chlorophenyl% 29 - 4% 2C4% 27% 2C5% 2C5% 27 - tetraphenyl - 2% 27H - 1% 2C2% 27 - biimidazole" on the market price. This is a very professional chemical substance, and its price is often affected by many factors.
First, purity has a great impact. If the purity is very high, it is almost perfect, and there is no impurity interference, the price will be high; on the contrary, if the purity is low and there are many impurities, the price may drop.
Second, the yield is also the key. If the preparation of this product is difficult and the output is scarce, the so-called "rare is more expensive", its price will be high; if the preparation process is mature and the output is considerable, the price may become more affordable.
Third, market demand also affects the price. If many industries have strong demand for it, demand exceeds supply, and prices rise; if demand is low, supply exceeds demand, and prices may decline.
Fourth, the price varies depending on the manufacturer. Manufacturers with high reputation and excellent craftsmanship have good product quality and high prices; new factories or unknown factories may have an advantage in order to compete for the market.
To know the exact price of this product, you need to consult merchants in the chemical raw material market or chemical product trading platforms to obtain accurate numbers.

2% 2C2% 27 - bis% 282 - chlorophenyl% 29 - 4% 2C4% 27% 2C5% 2C5% 27 - tetraphenyl - 2% 27H - 1% 2C2% 27 - biimidazole, this is an organic compound. The analysis of its stability needs to be viewed from many aspects.
First, chemical bonds, this compound contains many carbon-carbon bonds, carbon-nitrogen bonds and carbon-chlorine bonds. The carbon-carbon bond is quite stable, because its bond energy is quite high, it requires more energy to break. The carbon-nitrogen bond is also quite stable, which is beneficial to the maintenance of molecular structure. However, compared with the carbon-chlorine bond, the stability is slightly inferior. The chlorine atom has a certain electronegativity, or the carbon-chlorine bond has a certain polarity. Under certain conditions, it may easily react and cause molecular structure changes.
The second time looking at the spatial structure, the molecular structure of this compound is complex, containing multiple phenyl groups and imidazole rings. The large spatial structure enhances the intermolecular force, which increases its stability to a certain extent. However, the complex structure may also cause tension in the molecule. If the tension is too large, it may affect its stability. When the external conditions are suitable, the molecule may change the configuration to reduce the tension. This process may involve the breaking and formation of chemical bonds.
Furthermore, environmental factors have a great impact on its stability. At high temperatures, the thermal motion of molecules intensifies, and the vibration of chemical bonds increases. When the energy reaches a certain level, the chemical bonds may break, causing the compound to decompose. In case of strong acids and bases, the compound contains nitrogen and other atoms that can interact with acid and base, or undergo acid-base reactions, changing the molecular structure. If there is a specific oxidizing agent or reducing agent, it will affect its stability according to the oxidation state of each atom in the compound, or the redox reaction will occur.
Light is also an important factor. Light energy of a specific wavelength may be absorbed by the compound, causing electron transitions, triggering photochemical reactions, and changing the structure of the compound. Therefore, in order to maintain the stability of this compound, it is necessary to control temperature, avoid acid and base and strong oxidative reducing agents, and prevent light.
