| | 4-Nitrosophenol Usage And Synthesis |
| 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.
