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, a common aromatic hydrocarbon, through a process called nitration and subsequent reduction. Due to its amine group, aniline can participate in various chemical reactions, making it a valuable intermediate in organic synthesis. However, it is important to handle aniline with care, as it can be toxic and harmful if ingested or inhaled. Proper safety measures should be taken when working with this compound.
