[ 1 ] - Application of Mixed Micelle-Mediated Extraction for Selective Separation and Spectrophotometric Determination of P-Aminophenol Impurity in Pharmaceutical Formulations

A procedure for separation/preconcentration of para-aminophenol (PAP) in pharmaceutical formulation, based on cloud point extraction (CPE) as a prior step to determination by UV-Vis spectrophotometry has been developed. The analyte reacted with 4-dimethylamino benzaldehyde (DAB) in acidic media to form a shift base, which were separated and preconcentrated in a mixed micelle of the anionic surf...
