Diphenylamine-4-Sulfonic Acid Sodium Salt Analytical Grade ACS

The Diphenylamine-4-Sulfonic Acid Sodium Salt Analytical Grade ACS by Dinâmica, available at LojaLab, is a water-soluble redox indicator also known as sodium diphenylamine-4-sulfonate. In a properly conditioned medium, the reduced form is very faint or nearly colorless, while oxidation of the indicator produces a red-violet hue. The sodium form facilitates aqueous-solution preparation compared with less soluble forms, but concentration, solvent, stability and volume must still follow the method.
