5-methyl-2-(2-nitroanilino)thiophene-3-carbonitrile

5-Methyl-2- (2-nitroanilinyl) thiophene-3-formonitrile, this is an organic compound. Looking at its structure, the thiophene ring is the core, with a methyl group at the 5th position, a 2-nitroaniline group at the 2nd position, and a formonitrile group at the 3rd position.
In terms of its chemical properties, it contains a variety of functional groups, so its properties are diverse. Foronitrile groups have high reactivity and can participate in hydrolysis reactions. Under the catalysis of acids or bases, they are converted into carboxyl or amide groups. They can also participate in nucleophilic substitution reactions, and the carbon atoms of the nitrile group can be attacked by nucleophiles.
2 -Nitroanilinyl moiety, nitro is a strong electron-absorbing group, which reduces the electron cloud density of the benzene ring and weakens the nucleophilicity of the anilinyl group. However, under certain conditions, the amino group can still participate in the reaction, such as reacting with acid chloride or acid anhydride to form amides. At the same time, the nitro group can be reduced to an amino group under the action of a suitable reducing agent, and more reaction pathways can be derived.
Thiophene ring is aromatic and can undergo electrophilic substitution reaction. Because methyl is the power supply group, the electron cloud density of the thiophene ring will increase, and the electrophilic substitution reaction is more likely to occur in the ortho and para-position of methyl. However, the two positions are already connected with substituents, so the reaction check point may be more inclined to the four positions.
The physical properties of this compound, in view of its structure containing polar groups and aromatic rings, it is speculated that it should have a certain solubility in organic solvents, such as common ethanol, dichloromethane, etc. And due to a certain force between molecules, the melting point, boiling point or in a specific range. However, the exact physical properties still need to be accurately determined by experiments. In short, the rich functional groups of this compound endow it with diverse chemical properties, which has potential application value in the field of organic synthesis.

When storing 5-methyl-2- (2-nitroanilinyl) thiophene-3-formonitrile, many things should be paid attention to. This is an organic compound, and its properties may be active, so it is the first to prevent moisture. Moisture is easy to cause it to deteriorate. If the storage place is filled with water vapor, the compound may undergo reactions such as hydrolysis, which will damage its purity and quality.
It is necessary to avoid heat. High temperature can promote chemical reactions, or cause decomposition, polymerization, etc., which can change the properties of the substance. It should be placed in a cool place to keep the temperature constant and not affect its stability due to temperature fluctuations.
Furthermore, keep away from fire sources and oxidants. Because of its nitro and other groups, in case of open flame, hot topic or contact with oxidant, there is a risk of combustion and explosion. Storage must not have a fire source, and should be placed separately from the oxidant to prevent accidents.
In addition, it needs to be sealed and stored. In addition to moisture-proof, sealing can also avoid reactions with air components such as oxygen, and can also prevent its volatilization and loss, resulting in content changes.
When storing, the label must be clear. Remember the name, specification, date and other information in detail for future access and management, and can prevent confusion and misuse to ensure safe storage and use.
