4-Nitrophenol is an intermediate in the synthesis of paracetamol. It is reduced to 4-aminophenol, then acetylated with acetic anhydride. [6] 4-Nitrophenol is used as the precursor for the preparation of phenetidine and acetophenetidine, indicators, and raw materials for fungicides. Bioaccumulation of this compound rarely occurs.
with the formula HOC 6 H 4 NO 2.Three isomeric nitrophenols exist: . o-Nitrophenol (2-nitrophenol; OH and NO 2 groups are neighboring, a yellow solid.; m-Nitrophenol (3-nitrophenol, CAS number: 554-84-7), a yellow solid (m.p. 97 °C) and precursor to the drug mesalazine (5-aminosalicylic acid).

Furthermore, EPN has been observed to yield different metabolic products in animals, including as p-aminophenyl ethyl benzenethiophosphonate, O-ethyl phenylphosphonic acid, phenylphosphonic acid, O-ethyl phenylphosphonothioic acid, p-nitrophenol, and phenol. The p-nitrophenol can be further metabolized in the liver. The remaining amine is still ...

Synthesis of DNP (right) from phenol and nitric acid via 2-Nitrophenol and 4-Nitrophenol. DNP has the chemical formula HOC 6 H 3 (NO 2) 2. As a solid, it is a yellow, crystalline and has a sweet, musty odor. [1] [2] It sublimates, is volatile with steam, and is soluble in most organic solvents as well as aqueous alkaline solutions. [2]
