Benzenamine, N,N-dimethyl-3-nitro- - Introduction
N,N-Dimethyl-3-nitroaniline is an organic compound with the chemical formula C8H10N2O2. It is a deep red crystalline solid, soluble in alcohols and organic solvents, and slightly soluble in water.
N,N-Dimethyl-3-nitroaniline has important applications in organic synthesis. It can be used as a dye intermediate, and can also be used to prepare pesticides, medicines and photosensitive materials.
Its preparation method is usually prepared by the reaction of aniline and nitrous acid. Aniline is first reacted with nitrous acid to produce nitrosoaniline, and then nitrosoaniline is reacted with methanol to produce N-methyl-3-nitroaniline. Finally, N-methyl-3-nitroaniline is reacted with a methylating agent to give N,N-Dimethyl-3-nitroaniline.
When using and storing, it should be noted that N,N-Dimethyl-3-nitroaniline is a toxic compound. It may cause irritation and damage to the human body, and has the properties of irritating the eyes and skin. Personal protective equipment such as protective gloves, goggles and protective clothing should be worn during operation. In addition, should be away from the fire and oxidant, storage should avoid contact with strong acid or alkali. When waste is disposed of, it should be disposed of in accordance with local regulations. When used in laboratory or industrial production, relevant specifications and safe operating procedures should be followed.
