Description and Uses

4-Nitrophenol (also called p-nitrophenol or 4-hydroxynitrobenzene) is a phenolic compound that has a nitro group at the opposite position of hydroxyl group on the benzene ring. 4-Nitrophenol shows two polymorphs in the crystalline state. The alpha form is colorless pillars, unstable at room temperature, and stable toward sunlight. The beta form is yellow pillars, stable at room temperature, and gradually turns red upon irradiation of sunlight. Usually 4-nitrophenol exists as a mixture of these two forms. Generally, 4-nitrophenol is used in manufacturing of drugs (e.g., acetaminophen), fungicides, methyl and ethyl parathion insecticides, and dyes, and to darken leather.

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.
