Oxidation/reduction (redox) indicators are colorimetric reagents which show a distinct color change at a specific electrode potential. These are all organic compounds exhibiting reversible redox reactions. Examples include anilinic acid, diphenylamine, eriogreen, m-cresol-indophenol, methylene blue, and Nile blue.

However, diphenylamine is also used as an indicator in place of Ferroin where the use of H3PO4 is a must to bring the redox potential of the indicator near to the reaction redox potential. As, for phenolphthalein, it is an acid-base indicator that changes color along with the change in pH.
Redox Indicators are an indicators that undergoes a definite color change at a specific electrode potential,and shows a reversible color change between oxidized and reduced forms. Loba chemie offers wide range of redox indicators which are use as a Indicator in redox titrations.
