2-Bromo-4-chlorothiopheno [3,2-c] pyridine, the physical properties of this substance are really related to its many characteristics, let me elaborate.
Looking at its appearance, it is often crystalline and white like snow, just like the new snow that falls at the beginning of winter. The texture is delicate and shines slightly under the light, as if it contains fine stars.
When it comes to the melting point, at a certain temperature, its solid state and liquid state reach a wonderful balance, just like the moment when yin and yang meet between heaven and earth. When the outside temperature gradually rises to the melting point, this object melts like ice and snow, slowly turning from solid state to flowing liquid state, like a babbling stream, smart and full of changes.
Boiling point is also one of its important physical properties. Under a specific pressure environment, when the temperature rises to the boiling point, this object boils and rolls, turning into a gaseous state and rising up, just like a dragon rushing into clouds and breaking through fog, showing the magical power of material state transformation.
Its density is also fixed. Under established conditions, the quality of each unit volume is precise and stable, just like the established laws of heaven and earth, and cannot be easily shaken. This density characteristic makes it occupy a unique position in various material mixing systems, and it can sink or float according to this characteristic.
In terms of solubility, this substance can be uniformly dispersed and dissolved in a specific organic solvent, like a fish in water, just like raindrops merging into a river, difficult to distinguish from each other. However, in water, the solubility is quite limited, just like the barrier between oil and water, it is difficult to blend. This property determines its behavior differences in different media, and is of great significance in many processes such as chemical synthesis, separation and purification.
In addition, its refractive index is also a unique symbol. When light passes through this object, the direction of light changes quietly, and the refraction angle precisely corresponds to its inherent refractive index, just like the unique trajectory that light follows in the material world. This property plays an indispensable role in optical research and applications.
The above physical properties are intertwined to outline the unique physical features of 2-bromo-4-chlorothiopheno [3,2-c] pyridine, which lays a solid foundation for its research and application in many fields such as chemistry and materials.

To prepare 2-bromo-4-chlorothiopheno [3,2-c] pyridine, the following ancient method can be used.
First take appropriate starting materials, such as compounds containing thiophene and pyridine structures, which may already exist in the same molecule or need to be introduced in steps. If the starting material has only thiophene structure, the pyridine structure can be gradually built by ingenious reactions, such as electrophilic substitution reactions.
For the introduction of bromine and chlorine atoms, some attention should be paid to it. The brominating reagents with appropriate activity can be selected first, such as copper bromide, N-bromosuccinimide (NBS), etc. Under suitable reaction conditions, such as in an inert solvent, the temperature and reaction time can be controlled so that the bromine atom precisely replaces the hydrogen atom at the target position. At this time, close attention should be paid to the reaction process, which can be monitored by means of thin layer chromatography (TLC) to ensure that only bromine atoms are introduced at the desired check point.
After the successful introduction of bromine atoms, then select suitable chlorination reagents, such as thionyl chloride, phosphorus oxychloride, etc. In the same appropriate reaction environment, let the chlorine atom smoothly replace the hydrogen atom at another target position. This chlorination process also requires fine regulation of reaction parameters to avoid excessive chlorination or chlorination position deviation.
During the entire reaction process, the choice of solvent is very critical. According to the characteristics of each step of the reaction, a solvent with good solubility of the reactants and no adverse effect on the reactivity should be selected. And the reaction device should be clean and dry to prevent impurities from interfering with the reaction. At the same time, the product after the reaction needs to be separated and purified. The commonly used methods include column chromatography and recrystallization to obtain a pure 2-bromo-4-chlorothiopheno [3,2-c] pyridine product. In this way, the purpose of synthesizing this compound can be achieved.

We do not know with certainty the market price range of 2-bromo-4-chlorothiopheno [3,2-c] pyridine. This compound is uncommon, and its price may vary depending on many factors.
First, the difficulty of preparing this compound affects the price. If its synthesis requires complicated steps, special raw materials or harsh reaction conditions, the cost will be high, and the price will also rise. For example, the need for rare reagents, or the need for precise temperature and pressure control for the reaction, will increase the cost.
Second, market demand is also key. If there is strong demand for it in the fields of pharmaceutical research and development, materials science, etc., but the supply is limited, the price will go up; conversely, if there is little demand, the price may be relatively low.
Third, the supply sources are different, and the prices are also different. From large professional chemical reagent suppliers, due to quality control and brand factors, the price may be higher than that of small factory products.
If you want to know the exact price range, you can consult professional chemical reagent sales platforms, such as search banner, Buckingway, etc., which have price information of various chemicals; you can also contact chemical reagent dealers, who can provide more accurate quotations according to the current market conditions.
