Aniline (from Portuguese anil 'indigo shrub', and -ine indicating a derived substance) [6] is an organic compound with the formula C 6 H 5 NH 2.Consisting of a phenyl group (−C 6 H 5) attached to an amino group (−NH 2), aniline is the simplest aromatic amine.
Aniline Yellow is a yellow azo dye and an aromatic amine.It is a derivative of azobenzene.It has the appearance of an orange powder. Aniline Yellow was the first azo dye. it was first produced in 1861 by C. Mene.
One of the most relevant applications of the substance is the synthesis of 3-(diethylamino)phenol, key intermediate for the preparation of several fluorescent dyes (e.g., rhodamine B). Other uses for the compound include hair dye colorants and stabilizers for chlorine-containing thermoplastics. [4]
Certain azo dyes degrade under reductive conditions to release any of a group of defined aromatic amines. Since September 2003, the European Union has banned the manufacture or sale of consumer goods which contain the listed amines. Since only a small number of dyes produced those amines, relatively few products were actually affected. [4]
4-Aminodiphenylamine is a diphenylamine with an additional amine substituent. This dimer of aniline has various industrial uses, including as a hair dye ingredient, but also has raised concerns about toxicity by skin contact. [1] It is also a starting material for the synthesis of 6PPD, an antiozonant for various rubber products. [2]
John O’Hurley believes his character on The Young and the Restless character, Dr. James Grainger, could have done a better job on the show. “I don't think I kept a single patient alive in the ...
As with some other aromatic amines such as 2-naphthylamine, benzidine has been significantly withdrawn from use in most industries because it is so carcinogenic. In August 2010 benzidine dyes were included in the U.S. EPA's List of Chemicals of Concern. [ 7 ]
