Abstract:
The electrochemical study of a thiotriazole compound, 5-benzyl-4-(4'-methylphenyl-4H-1,2,4-triazole-3-thiol (TTA) was made with cyclic voltammetry (CV) and differential pulse voltammetry (DPV) using glassy carbon electrode (GCE) as working electrode and an Ag/AgCl reference electrode in the Britton- Robinson buffer. The best results for electrooxidation of TTA were obtained in basic media (in 10% ethanol-0.2 M NaOH). This compound display one irreversible oxidation peak, which is attributed to a dimerization process involving the formation of disulphide derivative (EC mechanism).Keywords:

4-Amino-5-hydrazinyl-4 H-1,2,4-triazole-3-thiol reacted with dimethyl acetylene-dicarboxylate, ethyl propiolate, ( E)-1,2-dibenzoylethylene, 2-(1,3-dioxo-1 H-inden-2(3 H)-ylidene)malononitrile, 2,3-dichloro-1,4-naphthoquinone, 2,3,5,6-tetrachloro-1,4-benzoquinone and 3,4,5,6-tetrachloro-1,2-benzoquinone to give various novel heterocylic compounds. Seven chemically synthesised compounds were screened for their in vitro antimicrobial activity against different strains of microorganisms. Most of the tested compounds exhibited an excellent antibacterial activity against Gram negative bacteria including Escherichia coli, Klebsiella pneumoniae and Pseudomonas aeruginosa compared to the activity of ciprofloxacin.

A variety of electroanalytical methods, e.g. DC polarography, cyclic voltammetry and controlled potential coulometry have been employed upon 3-arylazo-1,2,4-triazole derivatives, AAT; substituents affect the reduction potentials but do not alter the reduction pattern.
