(Elsevier Science BvAmsterdamHolanda, 2012)
A hemin-based molecularly imprinted polymer (MIP) grafted onto a glassy carbon electrode as a selective sensor for 4-aminophenol amperometric
(Elsevier Science SaLausanneSuíça, 2011)
OBTENCAO DE MESALAZINA (5-ASA) POR CARBOXILACAO DE P-AMINOFENOL
(1995-01-01)
The 5-aminosalicylic acid is usually prepared: 1. by the reduction of the azodye from diazotized aniline and salicylic acid and the posterior reduction of the formed compound; 2. for carboxylation with carbon dioxide under ...

An impedance study about the effect of pH on the electron transport rate at poly(o-aminophenol) film electrodes
(Bentham Science Publishers, 2014-06)
Impedance measurements on poly(o-aminophenol) (POAP) film electrodes in solutions of different pH were carried out. Impedance spectra were interpreted in terms of the modified electron hopping model described in F.J. ...

Human Hair Keratin Direct Electrochemistry and In Situ Interaction with p-Toluenediamine and p-Aminophenol Hair Dye Precursors using a Keratin Electrochemical Biosensor
(2020-03-02)
Keratin is the main protein in hair strands. The process of dyeing hair with permanent dyes is quite complex and involves oxidative reactions between precursors, such as p-toluenediamine (PTD) and p-aminophenol (PAP), and ...
