Use of nitroanilines for spectrophotometric determination of ethinylestradiol in pharmaceutical formulations
(Brasil, 2011)
Three nitroanilines (2-methoxy-4-nitroaniline, 2,4-dinitroaniline and 2-methyl-4-nitroaniline) were tested as spectrophotometric reagents for determination of ethinylestradiol (ETE). The determinations were based on ...
A comparative study on the cucurbit[7]uril-based indicator displacement assay for methyl Viologen. A theoretical and experimental perspective
(Wiley, 2023)
One colorimetric and one fluorescent-indicator displacement assay (IDA) were studied to assess their interaction with methyl viologen (MV), an herbicide commercially known as paraquat. The host–guest complexes formed by ...

Nitroanilines as Quenchers of Pyrene Fluorescence
(Wiley VCH Verlag, 2012-12)
The quenching of pyrene and 1‐methylpyrene fluorescence by nitroanilines (NAs), such as 2‐, 3‐, and 4‐nitroaniline (2‐NA, 3‐NA, and 4‐NA, respectively), 4‐methyl‐3‐nitroaniline (4‐M‐3‐NA), 2‐methyl‐4‐nitroaniline (2‐M‐4‐NA), ...
Effect of Ionic Liquid on the Determination of Aromatic Amines as Contaminants in Hair Dyes by Liquid Chromatography Coupled to Electrochemical Detection
(Mdpi Ag, 2012-07-01)
The room temperature ionic liquid (IL) 1-butyl-3-methylimidazolium bis-(trifluorometanesulfonyl) imide BMIm[NTf2] was used as a novel medium for improvement of separation and quantization of 16 aromatic amines typically ...
