An efficient method for the exclusive one pot synthesis of sodium salt of Benzidine diazo-bis-1-naphthyl amine-4-sulphonic acid (An Azo compound) under conditions of microwave irradiation. The Reaction was found to follow diazotization and condensation mechanism with removal of water molecules. Formation of product was confirmed through TLC, M.P. and spectral analysis. The reaction was carried out in a single pot without using solvent in a domestic microwave oven and Sodium 4-[{4-[(2-nitrophenyl)amino]phenyl}diazenyl] benzene sulfonate.
