The efficient method for the synthesis of ten cardanol azo dyes using aniline and its derivatives is described. Coupling reaction of cardanol affording high yield in slightly acidic media was observed. All the dyes were characterized by Fourier transform infrared spectroscopy, nuclear magnetic resonance spectroscopy, ultra violet - visible spectroscopy and mass spectrometry. The electrochemical behavior of these cardanol based azo dyes has been investigated by cyclic voltammetric technique by using sulfuric acid as supporting electrolyte. In addition, the effect of scan rate on dyes (2a 2j) showed irreversible one step two electron diffusion controlled reduction process. The peak potential was found to shift in the cathodic direction with increase in scan rate indicating the irreversible nature of the electrode reaction.
