#aniline

• 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.
• Aminophenol — A bifunctional organic compound with amphoteric character, derived from phenol by replacing a hydrogen atom on the aromatic ring with an amino group (-NH2). It has three positional isomers (ortho, meta, and para), of which para-aminophenol is the most industrially important, serving as a key structural intermediate in the synthesis of paracetamol, hair dyes, and photographic developers.
• 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.
• Anilide — An organic chemical compound structurally derived from an acid (usually a carboxylic acid) and aniline, by replacing a hydrogen atom in the amino group with an acyl radical. These substances belong to the class of aromatic amides and are of high importance in the pharmaceutical industry, serving as a base for synthesizing well-known analgesics and antipyretics, as well as in manufacturing artificial dyes and plastic stabilizers.
• 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.
• Anilism — A chronic or acute intoxication caused by the absorption of aniline or its derivatives into the body, primarily encountered as an occupational disease in the chemical and textile industries. The structural manifestation of this pathology includes severe cyanosis, caused by the formation of methemoglobin in the blood, headaches, vertigo, respiratory distress, and hepatic or renal impairment, requiring strict occupational safety monitoring in production spaces.
• Anisidine — An organic aromatic compound belonging to the amine family, derived from anisole and existing as three positional isomers (ortho, meta, and para); methoxyaniline. Industrially, it is used as an essential intermediate in the synthesis of azo dyes, pigments, and pharmaceuticals. In food biochemistry, p-anisidine is a primary reagent used to measure the secondary oxidation value of fats and oils by quantifying aldehyde formations.
