Enantioseparation of pesticides: A critical review
(2020-01-01)
The potential of chiral pesticides to exhibit stereoselective behavior in regards to activity, toxicity, degradation, bioaccumulation, and/or metabolism has inspired numerous studies, e.g., several works have investigated ...
On-line enantioseparation of chlorpheniramine using <beta>-cyclodextrin and carbon nanotubes after multivariate optimization
(Elsevier Science Bv, 2013-02)
Multiwalled carbon nanotubes are evaluated here as solid phase extraction (SPE) sorbent aiming to (±)-chlorpheniramine (CPA) enantioresolution with fluorimetric detection. β-cyclodextrin (CD) was added to the racemate ...
Chiral x Achiral Multidimensional Liquid Chromatography. Application to the enantioseparation of dintitrophenyl amino acids in honey samples and their fingerprint classification
(Elsevier Science, 2019-11)
Most HPLC enantiomer separations are performed with columns packed with a chiral stationary phase (CSP) operated with an achiral mobile phase. The intrinsically limited chemical selectivity of most CSPs to the simultaneous ...
Alternative and simple normal-phase HPLC enantioseparation of a chiral amino acid-type spin label derivative
(Sociedade Brasileira de Química, 2013)
Semipreparative enantioseparation of methamidophos by HPLC-UV and preliminary in vitro study of butyrylcholinesterase inhibition
(Wiley-Blackwell, 2012-02-01)
Many chiral pesticides are introduced into the environment as racemates, although their pesticidal activity is usually the result of preferential reactivity of only one enantiomer, while the other enantiomer may have toxic ...
Alternative and simple normal-phase HPLC enantioseparation of a chiral amino acid-type spin label derivative
(Sociedade Brasileira de Química, 2013-11-01)
In this work an alternative chromatographic process was developed for fractionating the (+)-(3R,4R) and ( - )-(3S,4S) enantiomers of the chiral trans β-amino acid trans-2,2,5,5-tetramethylpyrrolidine-3-amino-4-carboxylic ...
