Chiral assay
WebA new chiral molecularly imprinted polymer (MIP) sensor with dual recognition ability was developed for the highly selective separation of enantiomers with toxic side effects in drugs. The sensor contains double-stranded deoxyribonucleic acid (dsDNA) as the element that immobilizes the chiral molecular conformation: the dsDNA enables the imprinted cavities … WebSep 10, 2024 · We have demonstrated the efficient chiral analysis of fluorine-containing compounds by 19F NMR spectroscopy. The highly sensitive fluorine nucleus allowed chiral analysis of complex mixtures and even asymmetric reaction mixtures of multisubstrates. A single 19F NMR experiment was sufficient to determine the enantiomeric excesses and …
