Description
Solutions of diphenylamine are used to treat apples a few days
before harvest. Residue on apples’ surfaces of 10 ppm is
permitted by regulation in Australia, Canada, and the United
States.

Uses
Diphenylamine is an aromatic amine that was shown to exhibit antioxidant activities and is now used as an anti-scald agent. It is also used in the manufacture of a variety of substances, for instance, dye stuffs and their intermediates, pesticides, anthelmintic drugs, and as reagents in analytical chemistry laboratories. Diphenylamine is used in the manufactureof dyes, as a stabilizer for nitrocelluloseexplosives, and as an analytical reagent forcolorimetric tests for nitrate and chlorate.Other applications of Diphenylamineinclude preventing postharvest deteriorationof apple and peer crops; as an antioxidant inrubber and elastomer industry and in the per fumery. As a stabilizer for propellants andexplosives, it binds their degradation prod ucts thus prolonging the storage time of suchpropellants. Diphenylamine is used post-harvest to prevent superficial scald in
apples in cold store.
