Aniline is an organic compound with the chemical formula C6H5NH2. It is a colorless to pale yellow liquid that has a distinct odor. Aniline is primarily used in the production of dyes, plastics, and pharmaceuticals. It is derived from benzene and is classified as an aromatic amine due to the presence of an amino group attached to a benzene ring. Aniline is important in the chemical industry, particularly for creating azo dyes, which are widely used in textiles. However, it is also toxic and can be harmful if ingested or inhaled, necessitating careful handling and safety precautions during its use and production.
