- Diphenylamine is a secondary aromatic amine that is derived from aniline1. It is used as an industrial antioxidant, dye mordant and reagent21. It is also used in agriculture as a fungicide and antihelmintic2. Diphenylamine can be used to make Dische's diphenylamine reagent, which is a colorimetric method for measuring DNA concentration31. The reagent turns blue when heated with DNA, and the intensity of the color indicates the amount of DNA3.Learn more:✕This summary was generated using AI based on multiple online sources.

Application Diphenylamine may be used in the preparation of diphenylamine reagent, which is employed for the quantitative estimation of nucleic acid (DNA) from various biological sources by colorimetric method.www.sigmaaldrich.com/US/en/product/SIAL/112763Diphenylamine is widely used as an industrial antioxidant, dye mordant and reagent and is also employed in agriculture as a fungicide and antihelmintic.en.wikipedia.org/wiki/DiphenylamineDische's diphenylamine reagent consists of diphenylamine, glacial acetic acid, sulfuric acid, and ethanol. When heated with DNA, it turns blue in the presence of DNA. A more intense blue color indicates a greater concentration of DNA. Mechanism The acid converts deoxyribose to a molecule that binds with diphenylamine to form a blue substance.en.wikipedia.org/wiki/Dische_test

Diphenylamine is manufactured by the thermal deamination of aniline over oxide catalysts: 2 C6H5NH2 → (C6H5)2NH + NH3 It is a weak base, with a Kb of 10 . With strong acids, it forms salts. For example, treatment with sulfuric acid gives the bisulfate [(C6H5)2NH2] [HSO4] as a white or yellowish powder … See more
