C6H5NH2, commonly known as aniline, is an organic compound that consists of a benzene ring attached to an amino group. It is a colorless to slightly yellow liquid with a characteristic odor. Aniline is primarily used in the production of dyes, plastics, and pharmaceuticals, making it an important chemical in various industries. Aniline is soluble in water and can be produced through the reduction of nitrobenzene. It is also a precursor for many chemical compounds, including polyurethane and rubber. However, aniline is toxic and can be harmful if ingested or inhaled, necessitating careful handling and safety precautions.
