✦ Synopsis

Sodium N-bromo-p-nitrobenzenesulfonamide (bromamine-N) is useful as an oxidizing titrant. The synthesis, composition and structure are reported. Direct titrations of ascorbic acid, glutathione, thioglycolic acid, methionine, sulfite and arsenite are described. The procedures are simple and rapid; errors are within f 0.5%. The compound is a somewhat better titrant for those species than the chlorine analogs such as chloramine-T and chloramine-N.

Recent papers have described the synthesis of chloramine-N and dichloramine-N and evaluation of these reagents as redox titrants [ 1, 21. The present communication reports the synthesis and evaluation as a titrant of bromamine-N, the sodium salt of N-bromo-p-nitrobenzenesulfonamide.

The compound is characterized by its ultraviolet, infrared, and Fourier-Transform 'H-and '3C-nuclear magnetic resonance spectral data. Results are reported for titrations of glutathione, thioglycolic acid, methionine, ascorbic acid, sodium sulfite and sodium arsenite.
