Most of the biological interest in pyridine derivatives centres around nicotinamide which is the building block for the coenzymes, Nicotinamide adenine dinucleotide (NAD). Except for some polarographic studies, not many references are available on the electrochemical behaviour of nicotinamide. In the present investigation, the reduction of nicotinamide has been studied in non aqueous medium using glassy carbon electrode, in the solvent dimethyl formamide (DMF). Investigations have been carried out in the potential range +400 mV to -2400 mV at different scan rates using tetra alkyl ammonium perchlorates as the supporting electrolyte. Two cathodic peaks are observed around -1.6 V and -1.9 V, Depending upon the alkyl group used in the supporting electrolyte, the peak potentials are slightly varied. A small broad oxidation peak was observed on the reverse scan. From the value of peak currents, the value of n was determined to be one for each peak. Nicotinamide was found to get reduced in the ring yielding 1,4-di hydronicotinamide
