2 + -Amino-4-methyl-3-quinolinoformonitrile, this is an organic compound. It has many chemical properties, let me talk about them one by one.
First, its structural properties. The core of the compound is a quinoline ring, which is a class of nitrogen-containing heterocyclic rings, which endows it with specific stability and electronic properties. There is an amino group connected to the ring at 2 positions, and the amino group has an electron-giving effect, which can enhance the electron cloud density of the molecule and has a great impact on its reactivity. The methyl group at 4 positions is an alkyl substituent, which affects the molecular steric hindrance and electron cloud distribution. The 3-position formonitrile group is active and can participate in many reactions.
Let's talk about its physical properties. In terms of solubility, in view of its polar group amino group and methanonitrile group, it should have a certain solubility in polar solvents such as alcohols and ketones, but due to the existence of quinoline ring and methyl group, the solubility in non-polar solvents may not be good. In terms of melting point and boiling point, due to the interaction of hydrogen bonds and van der Waals forces between molecules, the melting point may be relatively high, and the boiling point is also within a certain range according to its structural characteristics.
As for chemical properties, amino groups can participate in nucleophilic substitution reactions and react with electrophilic reagents such as halogenated hydrocarbons to form new C-N bonds. Methanitrile groups have high chemical activity and can be hydrolyzed to form carboxyl groups or reduced to amine groups, expanding the diversity of molecular structures. The quinoline ring can undergo electrophilic substitution reaction, because the amino group gives electrons, the electron cloud density on the ring increases, which is conducive to the attack of electrophilic reagents at specific locations. And the compound may have certain optical and biological activities, and has potential application value in the fields of medicinal chemistry, materials science and other fields. It can be used as a key intermediate for the construction of complex organic molecules and used to synthesize compounds with special functions.

To prepare 2-amino-4-methyl-3-quinolinoformonitrile, there are various methods. The ancient method, or starting from the corresponding quinoline precursor, is modified to add amino, methyl and formonitrile groups.
First, select a quinoline derivative with a suitable substituent as the substrate. If there is a check point on the quinoline ring of the substrate that can be activated, an amino group can be introduced by nucleophilic substitution reaction. If halogenated quinoline is used as the starting material, it is reacted with ammonia or amination reagents under suitable conditions to replace the halogen atom with an amino group. Among them, the temperature of the reaction, the solvent and the type and dosage of the base are all key. If the temperature is too high, it may cause an increase in side reactions; if the temperature is too low, the reaction rate will be slow.
As for the introduction of methyl groups, methylation reagents are often used. For example, iodomethane, dimethyl sulfate, etc. are used to react with quinoline substrates under the catalysis of bases. The strength and dosage of bases must be precisely controlled. Strong bases or substrates overreact, and weak bases do not fully react.
And the addition of formonitrile groups, or cyanide reagents. The reaction of halogenated quinoline derivatives with potassium cyanide, sodium cyanide, etc. in the presence of phase transfer catalysts can form formonitrile groups. The choice of phase transfer catalysts is very important, which can promote the transfer of ions in the reaction system and improve the reaction efficiency. < Br >
There are new methods, or coupling reactions catalyzed by transition metals. For example, palladium, copper and other metals are used as catalysts to couple small molecules containing different functional groups to form target molecules. This approach requires detailed consideration of the type of catalyst and the structure of ligands in order to achieve high activity and selectivity. And the reaction conditions are mild, which can avoid many drawbacks of traditional methods.
Furthermore, in organic synthesis, the order of reaction steps is also about success or failure. Reasonable planning of each step of the reaction, or introducing stable groups first, and then other modifications to reduce side reactions and increase the yield of the target product. < Br >
The preparation of 2-amino-4-methyl-3-quinolinocarbonitrile is not a one-way process, and the advantages and disadvantages of each method should be weighed according to the actual situation, and the best one should be selected.

2 + -Amino-4-methyl-3-quinolinoformonitrile is an organic compound. When storing, many matters need to be paid attention to.
First choice of environment. This compound should be stored in a cool place. If the ambient temperature is too high, it may change its chemical properties or even cause decomposition reactions. It should also be placed in a dry place. The humid environment is prone to moisture, or adverse reactions such as hydrolysis, which affect its purity and quality. In the warehouse, the temperature and humidity should be controlled in a suitable range. The temperature is about 15-25 ° C, and the relative humidity should be 40% -60%.
Second time is the packaging consideration. The packaging must be tight to prevent contact with air. Because it contains active groups such as nitrile groups and amino groups, it is easy to react with oxygen, carbon dioxide and other components in the air. It is advisable to use containers with good sealing performance, such as glass bottles, plastic bottles, etc., and the mouth of the bottle should be tightly sealed. The packaging material should also be stable and do not chemically react with the compound.

Because of its certain reducing properties, it is easy to oxidize in case of oxidants; amino groups are alkaline and easily react in case of acid. Nitrile groups must be stored separately from acid and base substances. Substances of different chemical properties should be properly placed in different regions and shelves.
In addition, safety signs and records should not be underestimated. Clear safety labels should be posted at the storage place, indicating the compound name, danger and other key information for personnel to identify and prevent. At the same time, detailed records of warehousing time, quantity, batch and other information, once there is a problem, it is easy to trace and deal with.
