여러 가지 중요한 유기화합물의 원료로 쓰이는 외에 지시약으로도 쓰이고, pH 5.6~7.5에서 무색에서 황색으로 변한다.

화학적 성질

Yellow to tan crystals or powder


Used in the manufacturing of pharmaceuticals, fungicides, dyes.


manufacture of pharmaceuticals, fungicides, dyes. Indicator in 0.1% alcohol solution. pH: 5.6 colorless, 7.6 yellow.


4-Nitrophenol is used in dyestuff and pesticide synthesis, as a fungicide, bactericide, and wood preservative, as a chemical indicator, and as a substrate for experiments on cytochrome P450 2E1.


ChEBI: A member of the class of 4-nitrophenols that is phenol in which the hydrogen that is para to the hydroxy group has been replaced by a nitro group.

일반 설명

A white to light yellow crystalline solid. Contact may severely irritate skin and eyes. Poisonous by ingestion and moderately toxic by skin contact.

공기와 물의 반응

Soluble in hot water and more dense than water.

반응 프로필

4-Nitrophenol 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].


Toxic by ingestion.


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.

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.

Biological. Under anaerobic conditions, 4-nitrophenol may undergo nitroreduction producing 4- aminophenol (Kobayashi and Rittman, 1982). Estuarine sediment samples collected from the Mississippi River near Leeville, LA were used to study the mineralization of 4-nitrophenol under aerobic and anaerobic conditions. The rate of mineralization to carbon dioxide was found to be faster under aerobic conditions (1.04 x 10-3 μg/day/g dry sediment) than under anaerobic conditions (2.95 x 10-5 μg/day/g dry sediment) (Siragusa and DeLaune, 1986). In lake water samples collected from Beebe and Cayuga Lakes, Ithaca, NY, 4-nitrophenol at 50, 75, and 100 μg/L was not mineralized after 7 d. When the lake water samples were inoculated with the microorganism Corynebacterium sp., extensive mineralization was observed. However, at a concentration of 26 μg/L the extent of mineralization was much lower than at higher concentrations. The presence of a eucaryotic inhibitor (cycloheximide) also inhibited mineralization at the lower concentration but did not affect mineralization at the higher concentrations (Zaidi et al., 1989).
Surface Water. Photodegration half-lives of 5.7, 6.7, and 13.7 d were reported at pH values of 5, 7, and 9, respectively (Hustert et al., 1981).
Groundwater. Nielsen et al. (1996) studied the degradation of 4-nitrophenol in a shallow, glaciofluvial, unconfined sandy aquifer in Jutland, Denmark. As part of the in situ microcosm study, a cylinder that was open at the bottom and screened at the top was installed through a cased borehole approximately 5 m below grade. Five liters of water was aerated with atmospheric air to ensure aerobic conditions were maintained. Groundwater was analyzed weekly for approximately 3 months to determine 4-nitrophenol concentrations with time. The experimentally determined first-order biodegradation rate constant and corresponding half-life were 0.2/d and 3.47 d, respectively.
Photolytic. An aqueous solution containing 200 ppm 4-nitrophenol exposed to sunlight for 1–2 months yielded hydroquinone, 4-nitrocatechol, and an unidentified polymeric substance (Callahan et al., 1979). Under artificial sunlight, river water containing 2 to 5 ppm 4-nitrophenol photodegraded to produce trace amounts of 4-aminophenol (Mansour et al., 1989). A carbon dioxide yield of 39.5% was achieved when 4-nitrophenol adsorbed on silica gel was irradiated with light (λ >290 nm) for 17 h (Freitag et al., 1985).
Chemical/Physical. Wet oxidation of 4-nitrophenol at 320 °C yielded formic and acetic acids (Randall and Knopp, 1980). Wet oxidation of 4-nitrophenol at an elevated pressure and temperature gave the following products: acetone, acetaldehyde, formic, acetic, maleic, oxalic, and succinic acids (Keen and Baillod, 1985).

신진 대사 경로

4-[U-14C]Nitrophenol is conjugated as its b-glucoside (ca 22% of applied 14C) and gentiobioside, glc- b(126)-glc-b-4-nitrophenol (ca 64%), while about 7% of the parent remains unchanged in cell suspension cultures of Datura stramonium (L.). Gal-b-4-nitrophenol is found to be a minor metabolite.

Purification Methods

Crystallise 4-nitrophenol from water (which may be acidified, e.g. with N H2SO4 or 0.5N HCl), EtOH, aqueous MeOH, CHCl3, *benzene or pet ether, then dry it in vacuo over P2O5 at 25o. It can be sublimed at 60o/10-4mm. The 4-nitrobenzoate had m 159o (from EtOH). [Beilstein 6 IV 1279.]
