Nitrophenol

Nitrophenols are compounds of the formula HOC6H5-x(NO2)x. The conjugate bases are called nitrophenolates. Nitrophenols are more acidic than phenol itself. Nitrophenols are compounds of the formula HOC6H5-x(NO2)x. The conjugate bases are called nitrophenolates. Nitrophenols are more acidic than phenol itself. with the formula HOC6H4NO2. Three isomeric nitrophenols exist: The mononitrated phenols are often hydrogenated to the corresponding aminophenols that are also useful industrially. 2,4-Dinitrophenol (m.p. 83 °C) is a moderately strong acid (pKa = 4.89). 2,4,6-trinitrophenol is better known as picric acid, which has a well-developed chemistry. Nitrophenols are poisonous. Occasionally, nitrophenols contaminate the soil near former explosives or fabric factories and military plants, and current research is aimed at remediation.
