Studies on Sulfonamide Derivatives as Analytical Reagent. I. 2'-Mercapto-sulfonanilide Derivatives

Abstract

2'-Mercaptosulfonanilide derivatives were prepared by the reduction of 2, 2'-dithiobissulfonanilide with sodium sulfide and tested as the analytical reagents. These compounds were found to be useful reagents for the identification of copper (II), cobalt (II), and nickel (II), and the spectrophotometric determination of cobalt (II).
