Diphenylamine is an organic compound with the formula (C 6 H 5) 2 NH. The compound is a derivative of aniline , consisting of an amine bound to two phenyl groups. The compound is a colorless solid, but commercial samples are often yellow due to oxidized impurities. [ 5 ]
A redox indicator (also called an oxidation-reduction indicator) is an indicator which undergoes a definite color change at a specific electrode potential.. The requirement for fast and reversible color change means that the oxidation-reduction equilibrium for an indicator redox system needs to be established very quickly.
Benzidine is prepared in a two step process from nitrobenzene.First, the nitrobenzene is converted to 1,2-diphenylhydrazine, usually using iron powder as the reducing agent.
2-Nitrodiphenylamine is an organic chemical with the formula C 6 H 5 NHC 6 H 4 NO 2.It is a nitrated derivative of diphenylamine.It is a red solid, usually found in form of flakes or powder.
The color intensity of the resulting solution is then measured by a colorimeter and checked against a calibration curve to determine the nitrite ion concentration. [ 4 ] To analyze nitrate concentrations quantitatively, the sample is first passed through a copper-cadmium column to reduce the nitrate ions quantitatively to nitrite ions, and the ...
Aniline Blue WS, also called aniline blue, diphenylamine blue, China blue, or Soluble blue, is a mixture of methyl blue and water blue. It may also be either one of them. [ 1 ] It is a soluble dye used as a biological dye, [ 2 ] in fluorescence microscopy , appearing a yellow-green colour after excitation with violet light. [ 3 ]

Addition of potassium dichromate to this solution precipitates acridine bichromate. The bichromate is decomposed using ammonia. Acridine and its derivatives can be prepared by many synthetic processes. In the Bernthsen acridine synthesis, diphenylamine is condensed with carboxylic acids in the presence of zinc chloride.
