Synthesis and properties of sulfo-containing tetrazolium betaines and their formazan precursors

Chromogenic redox indicators - 3,5-diphenyl-2-(4-sulfophenyl)-2H-tetrazolium betaine and 2-(4-nitrophenyl)-5-phenyl-3-(4-sulfophenyl)-2H-tetrazolium betaine - were synthesized by the oxidative cyclization of 1,3-diphenyl-5-(4-sulfophenyl)formazan and 5-(4
