Application:

1)Aniline, phenylamine or aminobenzene is an organic compound with the formula C6H7N. Aniline is the simplest and one of the most important aromatic amines, being used as a precursor to more complex chemicals.

2) Being a precursor to many industrial chemicals, its main use is in the manufacture of precursors to  polyurethane . The largest application of aniline is for the preparation of methylene diphenyl diisocyanate  (MDI).

4)Other uses include  rubber  processing chemicals (9%),  herbicides  (2%), and dyes and pigments (2%).As additives to rubber, aniline derivatives such as  phenylenediamine [ disambiguation needed ] and  diphenylamine , are antioxidants. Illustrative of the drugs prepared from aniline is  paracetamol  (acetaminophen,  Tylenol ). The principal use of aniline in the dye industry is as a precursor to  indigo , the blue of  blue jeans .

5) Aniline is also used at a smaller scale in the production of the  intrinsically conducting polymer polyaniline .
