Primary aromatic amines are organic compounds that contain an amino group (-NH2) attached to an aromatic ring, which is a stable structure made up of carbon atoms arranged in a hexagonal shape. These compounds are important in various chemical processes and are often used as intermediates in the production of dyes, pharmaceuticals, and other chemicals. Due to their chemical properties, primary aromatic amines can be reactive and may pose health risks. Some of these compounds, such as aniline, are known to be toxic and potentially carcinogenic, making safety precautions essential when handling them in industrial and laboratory settings.
