Descripción

General description

4-Aminophenol (4-Hydroxyaniline) is an organic building block. Its quantification in water samples upto the detection limit of 8×10^-10mol l^-1 has been proposed by employing single-wall carbon nanotubes (SWNT)-nafion film coated glassy carbon electrodes. It is present as the main contaminant in pharmaceutical formulations of paracetamol. High-performance liquid chromatographic (HPLC) method with amperometric detection has been reported for its determination in various analgesic formulations. It has been reported to be formed from the reduction of 4-nitrophenol (Nip) under metal-free conditions catalyzed by N-doped graphene (NG).

Application

4-Aminophenol is suitable for use in the synthesis of 2,2-bis(4-aminophenoxy) benzonitrile [4-APBN], a monomer required for the preparation of series of polyamides and poly(amide-imide)s. It may be used as derivatization reagent to improve the ionization of aliphatic and aromatic aldehydes by paper spray ionization mass spectrometry.
