Description
4-Nitrophenol appears as a white to light yellow crystalline solid. 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.

Application
1. 4-Nitrophenol is used to manufacture drugs (e.g., acetaminophen), fungicides, methyl and ethyl parathion insecticides, and dyes and to darken leather.
2. Used as an intermediate for insecticides, fungicides, bactericides, and dyes; used as a leather treatment agent; Used to produce dyes, paints, rubber chemicals, and fungicides.
3. 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. is used to manufacture pharmaceuticals, fungicides, insecticides, and dyes and to darken leather. Indicator in 0.1% alcohol solution. pH: 5.6 colorless, 7.6 yellow. It can be used to prepare 4-aminophenol (4-AP), a key intermediate for the manufacture of analgesic and antipyretic drugs.
Storge & Handling
Keep away from heat, sparks, and flame. Keep away from sources of ignition. Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances. The floor of the storageroom must be impermeable to prevent the escape of liquids.
