To prepare 2 - (1H - pyrazole - 3 - yl) benzothiazole, the method is as follows:
First take an appropriate amount of benzothiazole as the base material and use it as the starting reactant, which is the basis of the reaction. In an appropriate reaction vessel, add a catalyst. The choice of catalyst is very critical, and it needs to be selected according to the reaction characteristics and past experience, which can accelerate the reaction process and make the reaction easier to occur. Then add the corresponding reagent containing 1H - pyrazole - 3 - group. The purity and dosage of this reagent have a great impact on the formation of the product.
The reaction temperature is also an important factor, and it needs to be precisely regulated within a specific range. Or need to use a water bath, oil bath, etc., to make the reaction system evenly heated and maintain temperature stability. This reaction may be carried out under heating conditions. When heating, pay attention to the heat, and do not make the temperature too high or too low to prevent side reactions from occurring and affect the purity and yield of the product.
During the reaction process, it may be necessary to stir to promote full contact of the reactants and speed up the reaction rate. Equipment such as a magnetic stirrer can be used to ensure uniform mixing.
After the reaction is completed, the product may be mixed with impurities. At this time, separation and purification are required. The method of recrystallization can be used, and an appropriate solvent can be selected to dissolve the product. After cooling and crystallization, the pure product can be precipitated. Column chromatography can also be used to separate the target product by taking advantage of the difference in the adsorption capacity of the adsorbent to different substances.
After many steps and careful operation, a relatively pure 2- (1H-pyrazole-3-yl) benzothiazole can be obtained. However, in the experimental process, every step needs to be treated strictly, and a slight mistake may lead to experimental failure or impure products.

2-% (1H-pyrazole-3-yl) benzimidazole is an organic compound, and its physical and chemical properties are crucial, which is related to the application of this compound in many fields.
When it comes to appearance, it is usually a white to light yellow solid powder, which is convenient for preliminary identification and determination during experiments and production. Its melting point is in a specific range, generally in the [specific melting point range]. The melting point is one of the important physical properties of the substance, which can help the purity identification. If the purity is quite high, the melting point range is usually narrow, and if it contains impurities, the melting point may be reduced and the range will be widened.
In terms of solubility, it has a certain solubility in common organic solvents, such as ethanol and dichloromethane. In ethanol, under specific temperature and concentration conditions, it can be partially dissolved. This property makes it possible to choose a suitable solvent according to its solubility when carrying out chemical reactions in solution form or preparing related preparations, so as to ensure the smooth progress of the reaction or achieve the ideal preparation effect.
In terms of chemical stability, it is relatively stable under conventional conditions. In the case of strong oxidizing agents or strong acid and alkali environments, chemical reactions may occur. In strong acidic solutions, the structures of pyrazole rings and benzimidazole may be damaged due to protonation and other effects, affecting their chemical structures and properties. This requires that during storage and use, it is necessary to avoid contact with such enhanced active substances to maintain their chemical structure integrity and stability.
In addition, the compound has certain spectral properties. In infrared spectroscopy, the absorption peaks corresponding to the chemical bond vibrations in the pyrazole ring and benzimidazole structure will appear at specific wavenumbers, such as the C-H bond stretching vibration peak on the pyrazole ring is located in [specific wavenumber range], which can be used to characterize and analyze its structure. In hydrogen nuclear magnetic resonance spectroscopy, hydrogen atoms in different chemical environments will appear signal peaks at corresponding chemical shifts, which can clarify the type and number of hydrogen atoms in molecules and provide an important basis for structural analysis.

I look at your question, and I am inquiring about the price of 2- (1H-pyrazole-3-yl) quinazoline in the market. However, the price of this product often varies for many reasons, and it is difficult to determine.
First, the quality is different, and the price is different. If this 2- (1H-pyrazole-3-yl) quinazoline is of good quality, high purity, and contains very few impurities, it is suitable for high-end scientific research or pharmaceutical needs, and its price is high; on the contrary, if the quality is poor and the purity is not high, it can only be used for general experimental or basic industrial purposes, and the price is slightly lower. < Br >
Second, the situation of supply and demand also affects its price. If the market demand for this product is strong, but the supply is limited, the so-called supply is in short supply, and the merchant must raise its price; if the supply exceeds the demand, the price may be reduced for promotion.
Third, the amount of purchase affects the price. If you buy in bulk, the cost can be reduced due to the scale effect, and the merchant may give a discount, and the unit price is lower; if you only buy in small quantities, there is no benefit of this scale, and the price may be high.
Fourth, the source is related to the price. If you buy it from a well-known factory, the quality may be more guaranteed, but the price may be high; if you buy it from a small factory or an emerging manufacturer, the price may be excellent, but the quality may need to be carefully inspected.
In summary, in order to know the exact price of 2- (1H-pyrazole-3-yl) quinazoline, it is necessary to carefully consider the above reasons and consult the supplier in person to obtain a more accurate price.

From the perspective of molecular structure, the compound contains specific groups and chemical bonds. 1H-pyrazole-3-yl is connected to naphthalimidazole to form a unique spatial structure. In this structure, the force of chemical bonds between atoms has a great impact on stability. Covalent bonds stabilize atomic connections. If the bond energy is high, the molecule is not easy to dissociate, and the stability is good.
Furthermore, the distribution of electron clouds within the molecule is also critical. The presence or absence of a conjugate system has a significant impact. Conjugate systems can delocalize electrons, reduce molecular energy, and improve stability. If the 2-%281H-%E5%90%B2%E5%93%9A-3-%E5%9F%BA%29%E8%8B%AF%E5%B9%B6%E5%99%BB%E5%94%91 molecule contains a conjugated structure, electrons flow in the conjugated system, enhancing the overall stability of the molecule.
External environmental factors should not be underestimated. When the temperature rises, the thermal motion of the molecule intensifies, and the vibration of the chemical bond increases. When the energy reaches a certain level, the chemical bond may be broken, and the stability will decrease. Changes in pH, if the compound contains protonated or deprotonated groups, will change the molecular charge state and electron cloud distribution, which in turn affects the stability.
Solvents also play a role. Different solvents interact with compounds differently. Polar solvents have good solubility to polar compounds and can affect molecular stability through solvation. Nonpolar solvents have different effects on non-polar or weakly polar compounds.
In summary, 2-%281H-%E5%90%B2%E5%93%9A-3-%E5%9F%BA%29%E8%8B%AF%E5%B9%B6%E5%99%BB%E5%94%91 stability is determined by its own molecular structure, such as chemical bonds, electron cloud distribution, etc., as well as external environment, such as temperature, pH, solvent and other factors.
