Studies on hydrazones at dropping mercury and solid electrodes

In quest of synthesizing compounds having antibacterial activity, we have prepared some sulphonamoyl-azopyrazoles and hydrazonopyrazolones. 1-Nitro-3-Methyl-4-(4'-sulphonamoyl)hydrazono pyrazolin-5-ones appear interesting from electrochemical point of view as they possess both -NO2 and -NH-N=C group in a single molecule. However, no attempt has been made to systematically study such compounds at d.m.e. as well as at solid electrodes. In order to throw light on the electrochemical behaviour of the compounds, studies have been undertaken in solutions of different acidity, concentration, solvent composition etc, and a redox mechanism has been postulated.
