ABSTRACT

 

1-[2’-Chloro-5’-Sulphophenyl] -3-Methyl-4-Azo– [2"-Carboxy-5"-Sulphonic acid] -5-Pyrazolone was prepared by diazotization of 4-sulphoanthranilic acid and then coupling with 1-[2’-Chloro-5’-Sulphophenyl]-3-Methyl-5-Pyrazolone in alkaline medium. It was characterized by elemental analysis and spectral studies. The transition metal chelates of the same were prepared with Cu2+, Ni2+ , Co2+ , Mn2+ and Fe3+ and characterized by IR spectral studies and physico chemical studies. The antimicrobial activity of ligand and its metal chelates were screened against various gram-positive (+) and gram-negative (%) organism. The results show that all these samples are more or less active agents against various organisms.
