Diphenylamine is a light tan to brown solid with a pleasant odor. Sinks in water. (USCG, 1999)|Diphenylamine is an aromatic amine containing two phenyl substituents. It has been used as a fungicide for the treatment of superficial scald in apples and pears, but is no longer approved for this purpose within the European Union. It has a role as a carotogenesis inhibitor, an antioxidant, an EC 1.3.99.29 [phytoene desaturase (zeta-carotene-forming)] inhibitor, an antifungal agrochemical, a ferroptosis inhibitor and a radical scavenger. It is an aromatic amine, a secondary amino compound and a bridged diphenyl fungicide.|In humans it may be irritating to mucous membranes. Methemoglobinemia has been produced experimentally. In veterinary use, it is one of active ingredients in topical agents for prevention and treatment of screwworm infestation. An indicator in tests for nitrate poisoning.

Handling and Storage

Precautions for safe handling

NO open flames. Closed system, dust explosion-proof electrical equipment and lighting. Prevent deposition of dust. Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.

Conditions for safe storage, including any incompatibilities

Provision to contain effluent from fire extinguishing. Separated from strong acids and oxidants. Store in an area without drain or sewer access.In general, materials which are toxic as stored or which can decompose into toxic components...should be stored in a cool, well-ventilated place, out of direct rays of the sun, away from areas of high fire hazard, and should be periodically inspected... Incompatible materials should be isolated from each other.
