Aniline

Anilidine, also known as aminobenzene, is an organic compound, chemical formula C6H7N, is a colorless oily liquid, heated to 370 °C decomposition, slightly soluble in water, soluble in ethanol, ether and other organic solvents.

Aniline is one of the most important amines. It is mainly used in the manufacture of dyes, drugs, resins, and can also be used as rubber vulcanization accelerators. It itself can also be used as a black dye. Its derivative methyl orange can be used as an indicator for acid-base titration.

On October 27, 2017, the list of carcinogens published by the International Agency for Research on Cancer of the World Health Organization was preliminarily sorted out for reference, and aniline was included in the list of 3 types of carcinogens.
