4-Aminophenol (or para-aminophenol or p-aminophenol) is an organic compound with the formula H 2 NC 6 H 4 OH. Typically available as a white powder, [ 3 ] it is commonly used as a developer for black-and-white film , marketed under the name Rodinal .
The molecular formula C 6 H 7 NO (molar mass: 109.13 g/mol) may refer to: Aminophenols. 2-Aminophenol; 3-Aminophenol; 4-Aminophenol; Nicotinyl alcohol ...
The classical methods for the production of paracetamol involve the acetylation of 4-aminophenol with acetic anhydride as the last step. They differ in how 4-aminophenol is prepared. In one method, nitration of phenol with nitric acid affords 4-nitrophenol, which is reduced to 4-aminophenol by hydrogenation over Raney nickel.
The three aminophenol isomers: Left: 2-Aminophenol (o-aminophenol) Center: 3-Aminophenol (m-aminophenol) Right: 4-Aminophenol (p-aminophenol) Aminophenol may refer to any of three isomeric chemical compounds: 2-Aminophenol; 3-Aminophenol; 4-Aminophenol; They are simultaneously an aniline and a phenol
2-Aminophenol is an organic compound with the formula C 6 H 7 NO. Along with its isomer 4-aminophenol , it is an amphoteric molecule and a reducing agent . It is a useful reagent for the synthesis of dyes and heterocyclic compounds . [ 3 ]
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.
