ABSTRACT

Electrochemical studies on heterocyclic class of compound containing thiazole moity is the topic of interest for many researchers. These heterocyclic compounds were used as amperometric reagents. In analytical chemistry. Rhodanine (2-Sulfanylidene-1, 3-thiazolidin-4-one) and its derivatives are used as amperometric reagents for trace determination of several transition metal ions. Amperometric titration can be conducted by utilizing redox system present, either before or after the end point. Electro-active species estimated quantitatively using amperometric titration technique.
