Description
Diphenylamine is found in coriander. Diphenylamine is used for control of superficial scald in stored apples Diphenylamine is the organic compound with the formula (C6H5)2NH. It is a colourless solid, but samples are often yellow due to oxidized impurities. It is a weak base, with a KB of 10 14. With strong acids, it forms the water soluble salt. Diphenylamine belongs to the family of Aromatic Homomonocyclic Compounds. These are aromatic compounds containig only one ring, which is homocyclic.

Toxicity Profile
Route of ExposureNot Available
Mechanism of ToxicityDiphenylamine uncouples mitochondrial oxidative phosphorylation, resulting in a decrease in hepatocellular ATP content and consequently hepatocyte injury (22). Short-term and long-term exposure in animal models results in altered haematological parameters, splenic erythropoiesis, splenic congestion and haemosiderosis (23).
