Description
Summary: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 ± 0.5%. The compound is a somewhat better titrant for those species than the chlorine analogs such as chloramine-T and chloramine-N.
