2-Amino-4-bromoquinoline

2-Amino-4-bromoquinoline is one of the organic compounds. It has a wide range of uses and is often a key intermediate in the synthesis of many drugs in the field of medicinal chemistry. The structure of geinoquinoline is common in many bioactive molecules. The amino and bromine atoms of 2-amino-4-bromoquinoline can provide an activity check point for subsequent chemical reactions. By chemical modification, compounds with specific pharmacological activities can be created, such as antibacterial, anti-tumor and other drugs.
In the field of materials science, it also has its application. Its structure gives specific electronic properties and stability, or can be used to prepare organic optoelectronic materials. For example, through rational molecular design and modification, it may become a component of organic Light Emitting Diode (OLED) materials, which can affect the luminous properties of devices due to their unique photophysical properties, such as luminous efficiency and color purity.
In addition, in the field of organic synthetic chemistry, 2-amino-4-bromoquinoline is often used as a substrate to participate in various organic reactions. The reactivity of its amino and bromine atoms is different, and it can selectively trigger nucleophilic substitution, electrophilic substitution and other reactions according to different reaction conditions and reagents, and then construct complex and diverse organic compounds, which contribute to the development of organic synthetic chemistry and help scientists create novel and unique organic molecules.

The synthesis method of 2-amino-4-bromoquinoline, as mentioned in ancient books, has many wonderful methods. One method is to use quinoline as the base, and first go through bromination to make the bromine atom enter the 4 position. This bromination method can use liquid bromine and quinoline in an appropriate solvent, add a catalyst such as iron powder, etc., to control the temperature, so that the bromine is selected and attached to the 4 position to obtain 4-bromoquinoline.
Then, 4-bromoquinoline undergoes amination. The method of amination can be used by the action of ammonia. Using 4-bromoquinoline and liquid ammonia in an autoclave, with an appropriate catalyst, the amino group in the ammonia replaces the bromine atom under high temperature and high pressure, and then obtains 2-amino-4-bromoquinoline. In this process, the choice of solvent, the control of temperature and pressure are all related to the effectiveness of the reaction.
There is another way to synthesize the quinoline precursor containing amino and bromine atoms from appropriate raw materials, and then cyclize it into 2-amino-4-bromoquinoline. For example, using o-amino benzoic acid derivatives and bromoaraldehyde as materials, through condensation, cyclization and other steps. First, the anthranilic acid derivative and the bromoaromatic aldehyde are condensed under the catalysis of acid or base to obtain the intermediate product, and then cyclized under appropriate conditions to obtain the target product. This approach requires attention to the appropriate reaction conditions at each step and the accurate proportion of raw materials to make the reaction smooth and the product pure.

2-Amino-4-bromoquinoline is one of the organic compounds. Its physical properties are quite impressive.
First of all, its appearance is often white to light yellow crystalline powder. This morphological feature makes it easy to identify in appearance, and the texture of the powder is also different from other things. The touch may be delicate, and it may have a unique luster in light.
As for the melting point, it is between 199-202 ° C. The melting point is the critical temperature at which the substance changes from solid to liquid. Within this temperature limit, 2-amino-4-bromoquinoline will undergo a phase change, which is crucial for its purification, identification, and control of the conditions involved in chemical reactions.
Solubility is also an important physical property. In common organic solvents, such as dimethyl sulfoxide (DMSO), it exhibits good solubility and can be uniformly dispersed to form a uniform solution. However, in water, its solubility is poor. This difference in solubility is due to the characteristics of its molecular structure, the quinoline ring contained in the molecule, and the functional groups such as amino and bromine atoms, which make it different from the interaction forces between different solvent molecules. The molecular structure of organic solvents is more compatible with 2-amino-4-bromoquinoline, and can interact with it through van der Waals force, hydrogen bonding, etc., and then dissolve; while the polarity and structure of water molecules interact weakly with the compound molecule, so it is difficult to dissolve.
In addition, the density, boiling point and other physical properties of 2-amino-4-bromoquinoline, although the relevant information has not been detailed, must also be related to similar compounds, affected by its molecular weight, intermolecular forces and other factors. Density determines the mass of its unit volume, and may play a role in storage, transportation, and some chemical reactions involving the relationship between volume and mass. Boiling point is related to its properties in the gas phase. Although it is not clear, it is an indispensable part of the physical properties system of the compound.
In short, the physical properties of 2-amino-4-bromoquinoline, such as appearance, melting point, solubility, etc., play a crucial role in its application in chemical research, industrial production, and related fields. According to its properties, researchers can rationally design experiments and choose reaction conditions to achieve the desired purpose.
