Today¡¯s experiments deal with a class of compounds called Azo dyes, compounds that contain two aromatic fragments connected by a N=N double bond. You may have encountered these in chemistry experiments as they are typical pH indicators. Methyl yellow, methyl orange, methyl red, congo red and alizarine yellow are some of the examples. They are straightforward to make and of industrial importance. Azo dyes are prepared in a two step reaction, the first being the synthesis of an aromatic diazonium ion from an aniline derivative. The next step is coupling of the diazonium salt with an aromatic compound (shown below is the preparation of methyl yellow).  The colours of azo dyes include different shades of yellow, red, orange, brown, and blue.

Local:
This compound, ,having N=N chromophore group, is used as a dye for lacquer, varnish, wax products, oil stains and styrene resins. It is used in insecticides. It is also used as an intermediate in the manufacture of Dyes (Chrysoidine, Induline, Solid Yellow & Acid Yellow);
