I haven't heard the exact market price of "3 - Bromomethyl + 7 - Chloro + Benzo [b] thiophene". This is a chemical substance, and its price varies depending on purity, source, and market supply and demand.
If it was in the context of "Tiangong Kaiwu", there was no concept of this fine chemical. At that time, it was mostly created with natural materials and simple processes. However, today is different from the past. Chemical research is advanced, and this compound may be used in scientific research, pharmaceuticals, and other fields.
In today's market, if it is a scientific research-grade pure product, its price must not be cheap. Its synthesis may require complex steps, specific reagents, and conditions. If the demand is small, the manufacturer's production scale is limited, and the cost is also high, and the price may be high. If the application is wide and the demand is large, the large-scale production can reduce the cost, and the price may be slightly easier. But the specific price is difficult to determine. It is necessary to check the chemical raw material trading platform and reagent supplier in detail to obtain a more accurate price.

3-Bromomethyl-7-chlorobenzo [b] thiophene, this is an organic compound. Its physical properties are unique, let me tell them one by one.
Looking at its appearance, under room temperature and pressure, or in the form of white to light yellow crystalline powder. This state is closely related to the arrangement of its molecular structure and the intermolecular forces. The intermolecular forces are moderate, causing it to be solid at room temperature and presented in the form of crystalline powder, with fine particles and uniform distribution.
As for the melting point, after many experiments, it is about a certain temperature range. Due to the existence of various forces between molecules, such as van der Waals force, hydrogen bonds, etc., these forces bind the movement of molecules. When the external temperature rises and the energy is sufficient to overcome these forces, the molecule breaks free and the substance changes from solid to liquid. This temperature is the melting point. Its melting point characteristics are of great significance in the purification, identification and control of related chemical reactions of compounds.
Solubility is also one of the key physical properties. In organic solvents, such as dichloromethane, chloroform, etc., the compound exhibits a certain solubility. Due to the principle of "similar miscibility", its molecular structure has a certain polarity, which matches the polarity of the organic solvent, so it is soluble. However, in water, the solubility is poor, and the polarity of the edge water is quite different from that of the compound. It is difficult to form effective interactions between molecules and cannot be uniformly dispersed.
In addition, the density of the compound also has its specific value. Density is influenced by molecular mass, molecular volume, and the way molecules are deposited. Its density characteristics provide important parameters for operations such as mixing and separation of substances.
Furthermore, its boiling point is also an important physical property. When the temperature rises to the boiling point, the compound changes from liquid to gaseous state, and the molecule obtains enough energy to get rid of the liquid phase. The level of boiling point is closely related to the strength of the intermolecular force, which plays a key guiding role in the distillation and separation of compounds.
The physical properties of this 3-bromo-methyl-7-chlorobenzo [b] thiophene are indispensable basic information in many fields such as organic synthesis and drug development, and have significant guiding value for related research and practice.

The chemical properties of 3-bromomethyl-7-chlorobenzo [b] thiophene are well-researched. In this compound, the presence of bromomethyl and chlorine atoms endows it with unique reactivity.
Let's talk about bromomethyl first. The bromine atom has good departure properties, which makes the compound active in nucleophilic substitution reactions. In case of nucleophiles, bromine ions are easy to leave, and nucleophiles can attack carbon positive ion intermediates, resulting in substitution reactions. For example, with alcohol nucleophiles, ether compounds can be formed; with amine nucleophiles, nitrogen-containing derivatives can be formed.
Furthermore, 7-chlorine atoms, although the departure of chlorine is slightly inferior to bromine, can also participate in specific reactions. Under appropriate conditions, chlorine atoms can be replaced by nucleophiles, and then the molecular structure can be modified. At the same time, the electronegativity of chlorine atoms affects the electron cloud distribution of the benzo [b] thiophene ring, changing its aromaticity and reactivity.
In addition, the benzo [b] thiophene ring itself has aromaticity, giving the compound a certain stability. However, due to the substitution of bromo methyl and chlorine atoms, the electron cloud distribution changes and the aromaticity is also fine-tuned. This compound can participate in various aromatic electrophilic substitution reactions, and its reaction check point is affected by the localization effect of the substituent.
And because of its structure containing sulfur atoms, the lone pair electrons of sulfur atoms can participate in the reaction, so that the compound has potential coordination ability and can form complexes with metal ions, which may be used in the field of catalysis. In short, the chemical properties of 3-bromomethyl-7-chlorobenzo [b] thiophene are rich and diverse due to the interaction of various parts of the structure, and may have broad application prospects in the fields of organic synthesis and materials science.
