4-Nitrosophenol Chemical Properties,Uses,Production
Chemical Properties
black solid
Uses
Dyes.
Hazard
Dangerous fire and explosion risk, reacts violently with acids and alkalies, may explode spontaneously, intraplant transport must be in tightly covered steel barrels.
Safety Profile
Poison by parented and intraperitoneal routes. Mutation data reported. An irritant and sensitizer. Many nitroso compounds are carcinogens. A very dangerous fire and explosion hazard. When exposed to heat or flame, it burns explosively. Contamination by acid or alkali may cause ignition . Can heat spontaneously and cause fire. When heated to decomposition it emits toxic fumes of NOx. See also NITROSO COMPOUNDS.
Purification Methods
4-Nitrosophenol forms yellow crystals from xylene, *C6H6 (m ~144o) or Et2O (m 128-129o, dec). [Beilstein 7 H 622, 7 II 574, 7 III 3367.]
