FenylNH2

FenylNH2 is a common chemical formula representing aniline. Aniline is an organic compound with the formula C6H5NH2. It is a primary aromatic amine, meaning it consists of a phenyl group (C6H5) attached to an amino group (NH2). Aniline is a colorless, oily liquid that darkens upon exposure to air and light, eventually turning dark brown. It has a distinctive, somewhat unpleasant odor.

Aniline is an industrially important chemical, serving as a precursor to a wide range of products. It is primarily used in the manufacture of polyurethane, which finds applications in foams, coatings, and adhesives. It is also a key intermediate in the production of dyes, particularly azo dyes, which are widely used in textiles, printing, and food coloring. Furthermore, aniline is utilized in the synthesis of pharmaceuticals, rubber processing chemicals, and pesticides.

The synthesis of aniline is typically achieved through the reduction of nitrobenzene. Common methods include catalytic hydrogenation or the use of iron and acid. Aniline is toxic and can be absorbed through the skin. Exposure can lead to methemoglobinemia, a condition where the blood's ability to carry oxygen is reduced. Proper handling procedures and protective equipment are essential when working with aniline. Its reactivity stems from the presence of the amino group, which can undergo various chemical reactions, including acylation, alkylation, and diazotization.
