4-Bromopyridine hydrochloride (1:1), an organic compound, has the characteristics of both 4-bromopyridine and hydrochloric acid. Its properties are stable, and it can react with strong oxidants and strong bases.
Looking at its physical properties, it is a white to light yellow crystalline powder under normal conditions, with hygroscopicity, and is easily soluble in water, methanol, and ethanol. Due to the formation of hydrogen bonds between hydrochloride and polar solvents, its solubility can be increased. Its melting point is quite important, about a specific temperature range, and its purity can be determined by melting point measurement.
In terms of chemical properties, the pyridine ring of 4-bromopyridine is basic, and the lone pair electrons on the nitrogen atom can bind protons. After forming a salt, this basicity can still be exhibited under certain conditions. The bromine atom is highly active and can participate in a variety of reactions. For example, in nucleophilic substitution reactions, bromine atoms in halogenated hydrocarbons can be replaced by nucleophiles, such as with sodium alcohols, bromine can be replaced by alkoxy groups to form corresponding ether compounds; when reacted with amines, nitrogen-containing derivatives can be prepared. In addition, pyridine rings can also participate in electrophilic substitution reactions, but due to the electron-withdrawing action of nitrogen atoms, the reaction check point is slightly different from that of benzene rings, and most of them occur at 4-Bromopyridine hydrochloride is widely used in the field of organic synthesis, and can be used as an intermediate to produce fine chemicals such as drugs, pesticides, and dyes through a series of reactions.

4-Bromopyridine hydrochloride (1:1) is useful in various fields. In the field of Guanfu medicinal chemistry, it is a key material for the synthesis of miraculous medicines. With its lively chemical properties, it can react with many reagents to build delicate molecular structures, and is often used as an important cornerstone when developing antibacterial and antiviral drugs.
In the field of materials science, it also develops its capabilities. It can participate in the preparation of materials with special functions, such as those with unique electrical and optical properties. Because of its unique structure, it can impart different properties to materials, or enhance their stability, or improve their conductivity and luminescence.
In addition, in the field of organic synthesis, it is a powerful tool. With this, chemists can build complex organic molecules. Through clever reaction design, 4-bromopyridine hydrochloride (1:1) can introduce specific functional groups to push the reaction in the desired direction, paving the way for the synthesis of novel organic compounds. Such as the construction of nitrogen-containing heterocyclic compounds, this substance often plays a key role in the development of organic synthetic chemistry.

To prepare 4-bromopyridine hydrochloride (1:1), you can follow the following method.
First take an appropriate amount of 4-bromopyridine and place it in a clean reaction vessel. This reaction vessel should be made of glass, because of its stable chemical properties, it is not easy to have side reactions with the reactants.
Add an appropriate amount of hydrochloric acid dropwise to the container containing 4-bromopyridine. When adding hydrochloric acid dropwise, be sure to control the dropwise speed, not too fast, to prevent the reaction from being too violent and out of control. During this process, it is advisable to keep stirring to fully contact the reactants and accelerate the reaction. A magnetic stirrer can be selected for the stirring device, which is evenly stirred and easy to operate.
During the reaction, changes in the system can be observed. Generally speaking, there will be heat release, so it is necessary to pay attention to the reaction temperature. Excessive temperature may cause side reactions, resulting in impure products. If the temperature rises too rapidly, appropriate cooling measures, such as cold water baths, can be used to maintain the reaction temperature within an appropriate range.
After the hydrochloric acid is added dropwise, continue to stir for a period of time to ensure complete reaction. This length of time depends on the actual reaction situation, usually about several hours. After the reaction is completed, the product can be separated and purified.
The method of reduced pressure distillation is used to remove excess solvent and unreacted hydrochloric acid from the system. Vacuum distillation can reduce the boiling point of the substance, achieve separation at a lower temperature, and avoid the decomposition of the product due to high temperature. Subsequently, a suitable organic solvent can be selected to recrystallize the product. The solvent for recrystallization needs to have a high solubility of the product at high temperature, but a low solubility at low temperature, and does not chemically react with the product. After multiple recrystallization, a pure 4-bromopyridine hydrochloride (1:1) can be obtained. The whole process requires careful operation and strict control of each step condition to obtain a satisfactory product.

The market price of 4-bromopyridine hydrochloride (1:1) is difficult to determine quickly. The price often varies due to various reasons, such as the supply and demand of the market, the cost of production, the quality of quality, and the location and season of sale.
Looking at the market conditions of the past, if the quality is ordinary and the batch is still small, the price per gram may be in the tens of yuan. However, if the purchase volume is quite large, the merchant may offer discounts for promotion, and the unit price may be reduced. If you want high quality and special specifications, the price will be higher.
If the market for chemical raw materials is stable and the supply is sufficient, the price may decrease steadily. On the contrary, if the raw materials are scarce, the cost of the system will rise, such as the price of bromine and other raw materials will increase, resulting in a significant increase in the cost of producing 4-bromopyridine hydrochloride, and its market price will also rise.
And due to the different economic conditions and logistics costs in different regions, the price is also different. In prosperous cities, the demand is large, the logistics is convenient, or the price is slightly lower due to competition; in remote places, the logistics is inconvenient, and the cost is increased, or the price is high.
In short, in order to know the exact market price, it is necessary to carefully observe the current market dynamics and consult the supplier to obtain an accurate price.
