P-Nitrophenol CAS 100-02-7

What is p-Nitrophenol?

Para-Nitrophenol,also called p-nitrophenol or 4-Nitrophenol, 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.
