#aromatic amine

• Aminobenzene — The official systematic name for aniline, representing the simplest primary aromatic amine consisting of a benzene ring directly bonded to an amino group (-NH2). This oily liquid, colorless when pure but turning brown upon exposure to air, has a molecular structure that serves as a fundamental raw material in the industrial synthesis of azo dyes, pharmaceuticals, vulcanization accelerators, and plastics.
• Aniline — The simplest representative of primary aromatic amines, with the chemical formula C6H5NH2. It appears as an oily liquid, colorless when pure, but rapidly turning brown upon contact with air due to oxidation. It is a toxic substance with a characteristic pungent odor, utilized as a fundamental raw material in the industrial synthesis of synthetic dyes, pharmaceuticals, plastics, vulcanization accelerators, and various intermediate compounds in the chemical industry.
• Aniline — The simplest primary aromatic amine (with the chemical formula C6H5NH2), appearing as an oily liquid, colorless when pure, but darkening rapidly in contact with air due to oxidation. It represents a raw material of critical structural importance in the global chemical industry, being the foundation for manufacturing synthetic dyes (aniline dyes), polyurethanes, vulcanized rubber, pesticides, and numerous pharmaceuticals.
