Metabolite Identification
Common Name4-Nitrophenol
Description4-Nitrophenol, also known as niphen or PNP, belongs to the class of organic compounds known as nitrophenols. Nitrophenols are compounds containing a nitrophenol moiety, which consists of a benzene ring bearing both a hydroxyl group and a nitro group on two different ring carbon atoms. 4-Nitrophenol exists as a solid, possibly soluble (in water), and an extremely weak basic (essentially neutral) compound (based on its pKa) molecule. 4-Nitrophenol exists in all living species, ranging from bacteria to humans. 4-Nitrophenol is a potentially toxic compound.
