The synthesis method of 4-bromopyridine-3-nitrile often involves several paths. First, it can be prepared from pyridine-3-nitrile through bromination reaction. In a suitable reaction system, select suitable brominating reagents, such as liquid bromine, N-bromosuccinimide (NBS), etc. Taking liquid bromine as an example, in a suitable solvent, such as dichloromethane and carbon tetrachloride, under the catalysis of catalysts such as iron powder and iron tribromide, pyridine-3-nitrile undergoes electrophilic substitution reaction with liquid bromine, and bromine atoms selectively replace hydrogen atoms at specific positions on the pyridine ring to generate 4-bromopyridine-3-nitrile. This process requires precise control of the reaction temperature, reagent dosage and reaction time, and the yield and purity of the product will be affected due to differences in reaction conditions.
Second, it can be synthesized from 4-bromopyridine by cyanylation. 4-bromopyridine is used as raw material to react with cyanide reagents, such as cuprous cyanide (CuCN) and potassium cyanide (KCN), under the action of suitable organic solvents and catalysts. For example, dimethylformamide (DMF) is used as solvent, and suitable ligands, such as 1,10-phenanthroline, are added to promote the nucleophilic substitution of cyanide to bromine atoms to achieve the synthesis of 4-bromopyridine-3-nitrile. In this path, the cyanide reagent is more toxic, and safety procedures must be strictly followed during operation to ensure the safety of experimental personnel and the environment is not polluted.
Furthermore, it can be synthesized by constructing a pyridine ring. Pyridine rings are constructed by multi-step reaction with appropriate raw materials containing bromine and cyanyl groups. For example, under alkali catalysis, specific bromoenone and cyanide-containing nitrile compounds are cyclized to form pyridine rings, which in turn generate 4-bromopyridine-3-nitrile. Although this method is complicated, it can obtain satisfactory results due to proper control of raw material selection and reaction conditions. When synthesizing 4-bromopyridine-3-nitrile, the advantages and disadvantages of each method should be weighed according to the actual needs and conditions, and the optimal route should be selected to achieve the purpose of efficient, economical and environmentally friendly synthesis.

4-Bromopyridine-3-formonitrile, this is an organic compound, and its physical properties are very interesting. Let me explain in detail.
Looking at its appearance, it is often a white-like to light-yellow crystalline powder. This state is easy to store and use, and also reflects the orderly arrangement of its molecules. The powder is delicate and may flash under light, as if there is a chemical mystery hidden in it to tell people.
As for the melting point, it is about 105-109 ° C. When the temperature gradually rises, the intermolecular force begins to weaken, the lattice structure gradually loosens, and the substance slowly changes from solid to liquid. This melting point characteristic is crucial for its purification and identification, like an accurate ruler, which can measure its purity.
Solubility is also an important physical property. In common organic solvents such as dichloromethane, N, N-dimethylformamide (DMF), it has good solubility. In dichloromethane, it can be rapidly dispersed to form a uniform solution, and the molecules interact with the solvent molecules and blend with each other. In water, its solubility is poor. Due to the weak force between water molecules and 4-bromopyridine-3-formonitrile molecules, it is difficult to break the interaction between its own molecules and dissolve it.
Although its density is not intuitive, it also has its significance. The density data reflects the compactness and mass distribution of molecules. Through accurate measurement, its density under specific conditions can be known, and this data is indispensable for material calculation in chemical production.
The physical properties of 4-bromopyridine-3-formonitrile, from appearance, melting point, solubility to density, all contain the delicate chemistry, which lays the foundation for its application in many fields such as organic synthesis and drug development, and is an important beginning to explore its chemical mysteries.

4-Bromopyridine-3-nitrile, an important intermediate in organic synthesis, is widely used in many fields such as medicine and pesticides. As for its market price, it is difficult to determine with certainty, because many factors will affect its price.
The first to bear the brunt is the cost of raw materials. The synthesis of 4-bromopyridine-3-nitrile requires specific raw materials. If the supply of these raw materials is scarce or the price of 4-bromopyridine-3-nitrile rises due to market fluctuations, the production cost of 4-bromopyridine-3-nitrile will also increase, which will lead to a rise in market prices.
Furthermore, the difficulty and efficiency of the production process also affect the price. If the production process is complicated, requires expensive equipment and delicate operations, or the production efficiency is low, the cost per unit product will increase, and the price will rise accordingly.
The market supply and demand relationship is a key factor. If the market demand for 4-bromopyridine-3-nitrile is strong and the supply is relatively insufficient, the price will rise; conversely, if the market demand is weak and the supply is excessive, the price may fall.
In addition, different manufacturers will set different prices due to their production scale, management level, and sales strategies. Manufacturers with large-scale production may have price advantages due to scale effects; manufacturers with efficient management can effectively control costs, and their product prices may be more competitive; and different sales strategies, such as pricing differences for different customer groups and sales regions, will also make market prices diverse.
In summary, in order to know the exact market price of 4-bromopyridine-3-nitrile, it is necessary to comprehensively consider the above factors, and it is necessary to pay attention to market dynamics in real time, and consult relevant manufacturers, distributors or professional chemical product trading platforms to obtain more accurate price information.
