2- (4-phenyl) pyridine compounds are mainly reflected in the following aspects:
1. ** Melting point and boiling point **: The melting point and boiling point of such compounds depend on the intermolecular forces, including van der Waals forces, hydrogen bonds, etc. The presence of phenyl and pyridine rings in the molecular structure increases the degree of conjugation and rigidity of the molecule, which generally enhances the intermolecular forces, resulting in relatively high melting points and boiling points.
2. ** Solubility **: Due to the fact that the molecule contains both aromatic phenyl groups and pyridine rings with a certain polarity, it has better solubility in organic solvents. For example, it has better solubility in common organic solvents such as chloroform, dichloromethane, toluene, etc. However, due to the fact that the overall polarity is not very strong, the solubility in water is poor.
3. ** Optical properties **: In view of its conjugated structure, such compounds often have certain optical activity. In the ultraviolet-visible region, it can absorb light of specific wavelengths, generate electron transitions, and exhibit characteristic absorption peaks. Some compounds may also exhibit fluorescent properties under appropriate conditions, which can be applied to the field of fluorescent materials.
4. ** Stability **: The conjugated system formed by phenyl groups and pyridine rings confers high stability to molecules. In general chemical environments, spontaneous decomposition reactions are not easy to occur. However, under extreme conditions such as strong acids, strong bases, or strong oxidants, its structure may be damaged.
5. ** Density **: Density is related to the relative molecular mass of the compound and the way the molecules are packed. Due to the relatively large and compact structure of such compounds, the density is usually higher than that of water.

To prepare 2 - (4 - thiophenyl) pyridine, there are many methods of synthesis, which are described in ancient methods.
One of them can be prepared by condensation reaction of thiophene and pyridine derivatives. First, take an appropriate amount of thiophene and place it in a clean reactor. Exhaust the air in the kettle with an inert gas such as nitrogen to prevent oxidation. Then slowly add specific pyridine derivatives. The choice of this derivative depends on the reaction conditions and the purity of the expected product. At the same time, add an appropriate amount of catalyst, such as some metal salts or organic bases, to promote the reaction. The reaction temperature should be controlled in a moderate range, usually between tens of degrees Celsius and 100 degrees Celsius, depending on the specific reactants and catalyst activity adjustment. During the reaction process, the reaction process is closely monitored. Thin-layer chromatography or other analytical methods can be used. When the reaction reaches the desired level, the product is extracted with an appropriate solvent. After multiple washes, drying, removing impurities, and then purifying by distillation or recrystallization, the target product can be obtained.
Second, the stepwise construction method is adopted. First, the intermediate containing thiophenyl is prepared, and the intermediate is formed by substitution reaction of thiophene with a specific reagent. Subsequently, the intermediate is reacted with the precursor of the pyridine ring to construct the pyridine ring. The control of reaction conditions is crucial, such as pH, temperature, reaction time, etc. When constructing the pyridine ring, classical synthesis reactions, such as variants of the Hantzsch reaction, can be used. After the reaction is completed, 2- (4-thiophenyl) pyridine is obtained by conventional operations such as separation and purification.
Third, transition metal catalytic coupling method can also be used. Select suitable transition metal catalysts, such as palladium, nickel and other complexes, to couple thiophenyl-containing halides with pyridyl boronic acids under basic conditions. This reaction requires strict control of the anhydrous and oxygen-free environment of the reaction system to ensure the activity of the catalyst and the smooth progress of the reaction. After the reaction, a series of post-treatments, such as filtration, extraction, column chromatography, etc., to obtain pure 2- (4-thiophenyl) pyridine products.

2- (4-hydroxybenzyl) imidazole, in the city, the range of its price is quite involved. Looking at the value of things in "Tiangong Kaiwu", we also know that the price of all things changes with time, land and quality.
This 2- (4-hydroxybenzyl) imidazole, if its quality is pure, good, and the market is prosperous, its price must be high. However, if there is a difference in quality, the system is not perfect, or the market is short, the price must be low.
At present, in the ordinary market, if the quality is fair and the supply and demand are suitable, the price per gram may be between tens and hundreds of dollars. If the quality is high, and it is urgently sought by all workers, for delicate and precious medicines, the price per gram may exceed a thousand gold. On the contrary, if the quality is poor, it is only suitable for crude business, and the price may not be more than a few dollars per gram.
If you want it, the price of 2- (4-hydroxybenzyl) imidazole in the market is about a few dollars per gram to a thousand gold. It really varies depending on the quality and requirements, and it cannot be generalized.
