Abstract
Oxidation of Trypan Blue with cerium(IV) ion in acid medium gives arenediazonium cation similar to the oxidation product of N,N-dimethyl-4-aminoazobenzene. Quantitative evaluation of the arenediazonium salt formed has been carried out spectrophotometrically after previous C-azo coupling with 2-naphthol.
