2-Pyridinecarbonitrile, 5-bromo-3-fluoro-

2-Pyridyl formonitrile, 5-bromo-3-fluorine, its physical properties are as follows. This substance is at room temperature, or in a solid state. Because its structure contains cyano groups, bromine atoms and fluorine atoms, the interaction between atoms results in strong intermolecular forces, so it tends to be in a solid state. Its melting point and boiling point have certain values due to the specific structure, but the exact value still needs to be accurately determined by experiments.
Looking at its appearance, it may be a white to off-white powder due to the light scattering and absorption characteristics of molecules. Its density is also one of the important physical properties, and its unit volume mass is determined by the type and arrangement of atoms in the molecule. Although there is no exact value, it can be speculated from similar structural compounds that the density may be within a certain range.
In terms of solubility, in organic solvents, because the cyanyl group has a certain polarity, or it can be slightly soluble in some polar organic solvents, such as ethanol, acetone, etc. However, the presence of bromine and fluorine atoms affects its solubility, or it is insoluble in non-polar organic solvents, such as n-hexane, benzene, etc.
The refractive index of this substance is also determined by its molecular structure, which can reflect the characteristics of light propagation in it. Although the specific value is not known in detail, in related research and applications, the refractive index may be a key factor to consider.
In summary, the physical properties of 2-pyridinonitrile and 5-bromo-3-fluorine are closely related to their own molecular structures, and their specific values need to be investigated in detail by experiments to clarify their characteristics and provide a definite basis for applications in related fields.

The chemical properties of 2-pyridinecarbonitrile, 5-bromo-3-fluorine are as follows:
This substance is an organic compound with unique chemical activity. From the perspective of substituents, the introduction of bromine atoms and fluorine atoms significantly changes the electron cloud distribution of the pyridine ring. Bromine atoms are relatively large, with certain electronegativity and volume effects, and fluorine atoms are extremely electronegative. Both reduce the electron cloud density of the pyridine ring and change the activity of the electrophilic substitution reaction on the ring.
In the nucleophilic substitution reaction, due to the existence of nitrile groups and halogen atoms, it can react with various nucleophilic reagents. Nitrile groups can participate in many reactions, such as hydrolysis to form carboxylic acids or amides, addition to nucleophiles under specific conditions, ring expansion or construction of new carbon-carbon bonds. Bromine and fluorine atoms can be used as leaving groups, which can be replaced when appropriate nucleophiles attack to form new derivatives.
In terms of redox properties, pyridine rings can be oxidized under the action of specific oxidants or reduced in the presence of suitable reducing agents, and the presence of substituents affects the check point and difficulty of redox reactions. In addition, due to the polarity of bromine, fluorine atoms and nitrile groups, the solubility of this substance in different solvents varies, affecting its reactivity and stability in solution. Overall, it is rich in chemical properties and has potential application value in the field of organic synthesis, which can be used to construct complex organic molecular structures.

The synthesis of 2-pyridyl formonitrile and 5-bromo-3-fluorine follows the path of organic synthesis. The synthesis of this compound can be carried out according to the following steps.
First, choose a suitable starting material, such as a pyridine derivative as the base. Halogenation of specific positions of the pyridine ring is first performed. To obtain the substitution of 5-bromo-3-fluorine, halogenating reagents can be used, such as brominating agents and fluorinating agents. When brominating, bromine atoms are introduced into the 5 position of the pyridine ring. The brominating agent used, such as N-bromosuccinimide (NBS), is used under suitable reaction conditions, such as a specific solvent (such as dichloromethane and other inert solvents), supplemented by appropriate temperature and catalyst (or an initiator can be added, such as azobisisobutyronitrile AIBN to initiate a free radical reaction), so that the bromine atoms are precisely replaced at the 5 position.
Then fluoride, choose a suitable fluorination reagent, such as Selectfluor, etc. The fluorination reaction needs to be controlled by the reaction conditions. Temperature and solvent properties are all related to the success or failure of the reaction and selectivity. Here, in the presence of an organic base (such as potassium carbonate, etc.), it can be reacted in an appropriate polar solvent (such as acetonitrile, etc.) to promote the introduction of fluorine atoms at the 3rd position.
Furthermore, the introduction of cyanyl groups. The nucleophilic substitution reaction can be used to use halogenated pyridine derivatives as substrates, and cyanide reagents, such as potassium cyanide (KCN) or sodium cyanide (NaCN), etc., with the help of phase transfer catalysts (such as tetrabutylammonium bromide, etc.), in a suitable solvent (such as dimethyl sulfoxide DMSO, etc.), so that the cyanyl group replaces the halogen atom, and finally obtains 2-pyridinonitrile, < Br >
The synthesis path is not limited to one end, and there may be other methods. However, this method is a common strategy in organic synthesis. Through various reactions such as halogenation and nucleophilic substitution, the required functional groups are introduced in sequence through multi-step operations to achieve the synthesis of the target compound.

I think what you are asking is about the market price range of 2-pyridinonitrile and 5-bromo-3-fluoride. However, the price of these materials often changes for many reasons, and it is difficult to cover it up.
Inter-city prices are related to supply and demand. If there are many applicants for this product, but there are few suppliers, the price will increase; on the contrary, if the supply exceeds the demand, the price may drop. And the difficulty of its preparation also affects the price. If the preparation requires complicated methods and precious materials, the cost will be high, and the price will follow.
Furthermore, the source is different, and the price is also different. Merchants from all over the world sell at different prices due to differences in procurement methods and operating costs. Some merchants may sell cheaply to capture the market, and some may sell cheaply because of their high quality.
And the market conditions are changing rapidly. Sometimes due to the price of raw materials, sometimes due to easier policies, the price of this product can fluctuate. Therefore, if you want to know its price, you should carefully observe the market conditions, consult various merchants, or observe the market report, and you can get a more accurate price. I regret that it is difficult to give the exact price range, but I hope this statement will be helpful to you in exploring the price.
