Safety Profile
Poison by ingestion, subcutaneous, intraperitoneal, intravenous, and intramuscular routes. Moderately toxic by skin contact. Human mutation data reported. Its exothermic decomposition causes a dangerously fast pressure increase. Murtures with diethyl phosphite may explode when heated. When heated to decomposition it emits toxic fumes of NOx. See also other nitrophenol entries and NITRO COMPOUNDS OF AROMATIC HYDROCARBONS.

Hazard Information

General Description
A white to light yellow crystalline solid. Contact may severely irritate skin and eyes. Poisonous by ingestion and moderately toxic by skin contact.
Reactivity Profile
4-NITROPHENOL(100-02-7) is a slightly yellow, crystalline material, moderately toxic. Mixtures with diethyl phosphite may explode when heated. Decomposes exothermally, emits toxic fumes of oxides of nitrogen [Lewis, 3rd ed., 1993, p. 941]. Decomposes violently at 279°C and will burn even in absence of air [USCG, 1999]. Solid mixtures of the nitrophenol and potassium hydroxide (1:1.5 mol) readily deflagrate [Bretherick, 5th Ed., 1995].
Air & Water Reactions
Soluble in hot water and more dense than water.
Hazard
Toxic by ingestion.
Health Hazard
Inhalation or ingestion causes headache, drowsiness, nausea, and blue color in lips, ears, and fingernails (cyanosis). Contact with eyes or skin causes irritation; can be absorbed through skin to give same symptoms as for inhalation.
