Reductive alkylation of p-aminophenol

Bulletin of the Academy of Sciences, USSR Division of Chemical Science, 1963
The reductive alkylation of p-aminophenol with n-butyraldehyde, isobutyraldehyde, isovaleraldehyde, propionaldehyde, and benzaldehyde has been described. Derivatives of p-aminophenol monoand dialkylated in the amino group have been obtained.

Effect of p-aminophenols on tyrosinase activity

Bioorganic & Medicinal Chemistry, 2014
Tyrosinase is involved in the synthesis of melanin in the skin and hair as well as neuromelanin in the brain. This rate limiting enzyme catalyzes two critical steps (reactions) in melanogenesis; the hydroxylation of tyrosine to form DOPA and the subsequent oxidation of DOPA into dopaquinone.

Electrocatalytic Synthesis of p-Aminophenol Using Fe‒Ag Composites

Russian Journal of Electrochemistry, 2023
p-Aminophenol was prepared by electrocatalytic hydrogenation of p-nitrophenol using Ag + Fe + Fe3O4 (or Fe2O3) composites as catalysts formed during heat treatment and electrochemical reduction of silver ferrite, AgFeO2. AgFeO2 samples were synthesized by co-precipitation method without and in the presence of a polymer (polyvinyl alcohol ...

The electrolytic preparation of p-aminophenol

Electrochimica Acta, 1969
Abstract An account is given of new methods for the electrochemical preparation of p-aminophenol by the reduction of nitrobenzene. It has been found that control of the electrode potential at a specific value using recently developed potentiostats brings about a marked improvement in the efficiency of the preparation.

Selective spectrophotometric determination of p-aminophenol and acetaminophen

Talanta, 1997
A specific spectrophotometric method was developed for the determination of p-aminophenol and acetaminophen. The method is based on the reaction of p-aminophenol at ambient temperature with sodium sulphide in presence of an oxidant to produce a methylene blue-like dye. Different oxidizing agents were tried, e.g. Ce(IV) and Fe(III). The colour developed
