2-Fluoro-4-bromopyridine is one of the organic compounds. It has specific physical properties, as described below.
First of all, its appearance, under room temperature and pressure, is mostly colorless to light yellow liquid, but it may also appear in a crystalline state under specific conditions. Looking at it, it has a certain transparency, soft luster, and no significant abnormal hue. This appearance characteristic makes it easy to initially identify in experiments and industrial operations.
Second, its melting point is about a specific temperature range. The determination of melting point depends on precision instruments and rigorous operation. The accuracy of its value is related to the purity and structural characteristics of this compound. At this temperature limit, the solid-liquid phase transition occurs quietly, and the balance of intermolecular forces also changes.
Furthermore, the boiling point is also one of the important physical properties. In atmospheric pressure environment, when a specific boiling point is reached, 2-fluoro-4-bromopyridine is converted from liquid to gaseous state. This process requires absorption of a certain amount of heat to overcome the attractive force between molecules. The level of boiling point is closely related to the size, shape and intermolecular forces of molecules, reflecting the strength of their volatility.
In addition to its solubility, it has a certain solubility in organic solvents such as ethanol and ether. Due to the fact that some groups in the molecular structure can form interactions such as hydrogen bonds and van der Waals forces with organic solvent molecules, it can be dispersed in the solvent system. However, in water, its solubility is relatively limited, because the polarity of water does not match the polarity of the compound molecule well, it is difficult to form an effective interaction.
In addition, density is also a property that cannot be ignored. Its density value is specific, reflecting the mass of the substance contained in the unit volume. This property is related to the delamination and separation of substances in the research and practical application of mixed systems. < Br >

2-Fluoro-4-bromopyridine is also an organic compound. Its chemical properties are particularly important and have a wide range of uses in the field of organic synthesis.
As far as its activity is concerned, the reactivity of this compound is greatly increased due to the introduction of fluorine and bromine diatoms. Fluorine atoms have strong electronegativity, which can change the electron cloud density distribution of the pyridine ring, and make the electron cloud on the ring biased towards the fluorine atom. This electronic effect not only affects the stability of the pyridine ring itself, but also has a significant impact on the nucleophilic and electrophilic reactivity.
Bromine atoms are also active functional groups. In many reactions, bromine atoms can be used as leaving groups. For example, in nucleophilic substitution reactions, bromine ions are easy to leave, providing an offensive check point for nucleophiles, thereby forming new carbon-heteroatomic bonds.
2-fluoro-4-bromopyridine can participate in coupling reactions such as the Ullmann reaction. Under suitable catalytic systems, its bromine atoms can be coupled with aryl halides, amines and other compounds to construct complex aromatic compound structures, which is of great significance in the fields of drug synthesis and materials science.
Furthermore, due to the high stability of fluorine atoms and the improvement of physical properties such as lipophilicity of compounds, the products obtained by the reaction of 2-fluoro-4-bromopyridine often have unique physical and biological activities. In organic synthesis chemistry, this compound is like a delicate masonry, laying the foundation for the construction of various complex organic molecular structures. With its unique chemical properties, it provides the possibility for the synthesis of new functional materials and bioactive molecules, which are indispensable in the fields of modern chemical research and industrial production.

The method of synthesizing 2-fluoro-4-bromopyridine has been known for a long time. The method of the past relies on many ingenious chemical changes to form this product step by step.
One method, often based on pyridine, introduces bromine atoms before specific parts of the pyridine ring. This step can be done by using brominating reagents, such as liquid bromine or N-bromosuccinimide (NBS), under suitable reaction conditions, such as specific temperatures and catalysts, so that bromine atoms fall precisely in the fourth position of the pyridine ring. The bromination process requires careful regulation of the reaction conditions to prevent side reactions, such as the formation of polybrominated products.
Then, fluorine atoms are introduced. This step can be used as a nucleophilic substitution method to react with brominated pyridine derivatives with fluorinated reagents, such as potassium fluoride. In order to make the reaction smooth, it is often necessary to choose a suitable solvent, such as dimethyl sulfoxide (DMSO), to enhance the solubility and reactivity of the reagent. And the reaction temperature and time are also crucial. If the temperature is too high or the time is too long, it may cause adverse reactions and damage the purity and yield of the product.
There is another method, which introduces fluorine atoms before the pyridine ring, and then undergoes the bromination step. This path requires careful selection of reaction conditions according to the effect of different substituents on the subsequent reactivity of the pyridine ring. When introducing fluorine atoms, it is also necessary to pay attention to the selectivity and efficiency of the reaction.
Synthesis of 2-fluoro-4-bromopyridine, various methods have their own advantages and disadvantages. Although the previous methods can produce products, there may be drawbacks such as complicated reaction steps, low yield, and difficult product separation and purification. Today, chemical technology is becoming more and more exquisite, and new synthesis methods may emerge one after another, but they are all inseparable from the principles of the previous basic methods. It is nothing more than striving for excellence in reaction conditions, reagent selection, and technological processes, in order to obtain better synthesis results.

The price range of 2-fluoro-4-bromopyridine in the market is difficult to determine. The price of this product often changes for many reasons.
First, the amount of production is related to the price. If it is widely available in the market, it is easy for everyone to obtain, and the price may be leveled; if the product is thin, there are many applicants and few suppliers, the price will be high.
Second, the degree of need is also the main reason. If at a certain time in a certain industry, the demand for 2-fluoro-4-bromopyridine is extremely strong, and those who compete to buy it will increase the price; if times change, the demand will be greatly reduced, and the price will also drop.
Third, the difficulty of making it also affects its price. If the preparation method is complicated, requires multiple work and materials, and takes a long time, the cost will be high, and it will be sold in the market, and the price is not cheap; if there is a simple method, the cost will be reduced, and the price may be low.
Fourth, the competition in the city has a significant impact. There are many merchants in the city competing for profits, or lowering prices to attract customers; if there is no one else competing, the price will be controllable.
In summary, if you want to know the exact price of 2-fluoro-4-bromopyridine, you should carefully observe the market situation and visit the merchants, or you can get a general idea. However, its price is volatile and changes in real time, so it is difficult to set a fixed price range.
