2,3-Dimethyl-4-nitroaniline - Introduction
4-Nitrodimethylaniline(4-Nitrodimethylaniline) is an organic compound. Its chemical formula is C8H10N2O2, and the structure has a methyl group and a nitro group substituted at the 2 and 3 positions of the benzene ring, and has two methyl substituents relative to aniline.
Properties 4-nitrodimethylaniline is a colorless to yellow crystalline solid. It has a lower melting point and boiling point, soluble in organic solvents such as ethanol and chlorinated hydrocarbons, insoluble in water. It is electrophilic in chemical reactions and can participate in electrophilic aromatic substitution reactions and oxidation reactions.
In terms of use, 4-nitrodimethylaniline is mainly used in organic synthesis, as an intermediate to participate in the synthesis of other compounds. It is also used as a raw material in the fields of dyes, pesticides and pharmaceuticals.
In terms of preparation, 4-nitrodimethylaniline is usually obtained by alkylation at the No. 2 and No. 3 positions of aniline, and then nitration with a mixture of nitric acid and sulfuric acid. The specific preparation method can be adjusted according to the experimental conditions and the requirements of the target product.
In terms of safety information, 4-nitrodimethylaniline is a toxic substance, which may cause irritation and injury to the human body. Pay attention to protective measures during operation, including wearing protective gloves, goggles and appropriate protective clothing. At the same time, it should be stored in a cool, dry and well-ventilated place, away from flammable materials and oxides.
