This is related to the physical characteristics of the matter. 2 - (5-mercury-2-hydroxybenzyl) naphthalimidazole derivatives, this substance has several physical characteristics.
In terms of appearance, it often takes a specific form. Or it is in a crystalline state, with a regular crystal shape and a certain geometric shape. Under the illumination of light, it may have a bright luster. Due to the orderly arrangement of molecules, the lattice structure is stable.
In terms of solubility, it shows different performance in specific solvents. In polar solvents, due to the formation of hydrogen bonds, dipole-dipole interactions, etc. between molecules and solvent molecules, or a certain solubility. However, in non-polar solvents, the solubility may be very small due to the large difference between molecular polarity and non-polar solvents.
Melting point is also an important physical property. The melting point of this derivative is determined by the intermolecular forces, including van der Waals forces, hydrogen bonds, etc. The intermolecular forces are strong, and higher temperatures are required to overcome this force to cause lattice destruction and material melting, so the melting point may be in a specific temperature range.
In terms of thermal stability, due to the strength of the chemical bonds between atoms in the molecular structure and the interaction between molecules, the structure can be maintained within a certain temperature range. However, if the temperature is too high, the chemical bonds may break, and the molecular structure changes, causing the decomposition of substances or other chemical changes.
In addition, its density is also one of the physical properties. Depending on the molecular mass and the way of molecular packing, in the solid state, the degree of tight packing of molecules varies, and the density also varies. The density affects its behavior in a specific environment, such as floating in solution.
In summary, the physical properties of 2- (5-mercury-2-hydroxybenzyl) naphthalimidazole derivatives are influenced by many factors such as molecular structure and intermolecular forces, and each property is interrelated to affect its performance in different scenarios.

This is a question about the chemical properties of the substance, but the Chinese symbols and garbled characters of the expression are doped. If it is speculated, it may be "What are the chemical properties of 2- (5-hydroxy- 2-mercaptophenyl) thioimidazole?"
This compound contains the structure of thiazole and imidazole. The thiazole ring and imidazole ring give it a unique electronic effect and spatial structure. From the perspective of electronic effect, heteroatoms such as nitrogen and sulfur have lone pairs of electrons, which can participate in electron delocalization and affect the reactivity and stability of the compound. In the chemical properties of
, due to the existence of nitrogen and sulfur atoms, the compound may have a certain alkalinity and can react with acids to form salts. In the nucleophilic substitution reaction, the lone pair electron of the heteroatom acts as a nucleophilic check point and reacts with the electrophilic reagent. And the aromatic ring structure makes the compound have certain aromaticity and can undergo aromatic electrophilic substitution reactions, such as halogenation, nitrification, sulfonation, etc. The substitution check point is affected by the localization effect of the substituent on the ring.
And because it contains hydroxyl groups and sulfhydryl groups, the hydroxyl groups can undergo esterification, oxidation and other reactions, and the sulfhydrate activity is also high, which can participate in the formation of disulfide bonds and other reactions, which This compound is rich in chemical properties and may have important application and research value in the fields of organic synthesis, medicinal chemistry, etc.

To prepare the complex of 2 - (5-hydroxyl-2-thiophenyl) pyridyl imidazole, the method is as follows:
First take an appropriate amount of 5-bromo-2-thiophenaldehyde, place it in a clean reaction vessel, use absolute ethanol as solvent, add pyridyl imidazole derivative according to a certain molar ratio, add an appropriate amount of potassium carbonate as base, stir well, and add nitrogen to remove the air in the system. Subsequently, add an appropriate amount of palladium catalyst, heat up to a certain temperature, such as 80-100 ° C, and continue to stir the reaction number, during which the reaction process is closely monitored, which can be observed by thin layer chromatography. After the reaction is completed, it is cooled to room temperature, the reaction solution is poured into water, extracted several times with ethyl acetate, the organic phases are combined, dried with anhydrous sodium sulfate, filtered, and distilled under reduced pressure to remove the solvent to obtain a crude product. The crude product is purified by silica gel column chromatography, and the eluent is prepared with petroleum ether and ethyl acetate in an appropriate ratio. Carefully eluted, the fraction containing the target product is collected, and then distilled under reduced pressure to obtain a pure 2 - (5-hydroxyl-2-thiophenyl) pyridinium imidazole.
Another method can first carry out the hydroxylation reaction of 2-thiophene formaldehyde to obtain 5-hydroxy- 2-thiophene formaldehyde, and then react with pyridyl imidazole under similar reaction conditions, catalyzed by base, in an organic solvent, under the action of catalyst, condensation reaction occurs. The subsequent treatment steps are similar to the previous method, and the target product can also be obtained. When operating, attention must be paid to the ratio of each reactant, reaction temperature, time and post-treatment conditions, which all have an important impact on the yield and purity of the product.

Nowadays, there are two - (five - two - two - two) tails and tails on the market. What is the price range?
The "five - two - tails" of the husband, although the exact meaning of it is not detailed, it can be determined according to common sense. Market vendors, places of buying and selling transactions, and prices of all kinds of goods often vary according to quality, supply and demand, and time and place.
If these two - (five-two-two-one-two) scallops are ordinary products, and the origin is quite abundant, and there is no shortage of supply in the city, and rare things that are not sought after by people at times, then the price may be relatively easy. Probably by analogy with common fruits and vegetables, if it is a general edible or daily use, the price may be between a few and dozens of words.
Let it be a rare and rare product, or it is born in a remote place and difficult to collect, or it is unique in shape and has different functions. It is valued by the world, but it is a rare product in the city. In this way, its price is not cheap, or it can reach hundreds of words, or even more than a thousand words.
However, these are all speculations, and it is difficult to determine the exact price range above the market. Because he does not know what the "five-two-two" refers to, nor does he know the market customs and supply and demand at that time. Only by examining the facts in detail can we get a more accurate price range.
