This review provides a brief survey of chiral separation of pharmaceutically active substances published over the last 3 years (2024–2024). Chiral separation of drugs is an important area of research. The control of enantiomeric purity and determination of individual enantiomeric drug … WebIn chemistry, a molecule or ion is called chiral (/ ˈ k aɪ r əl /) if it cannot be superposed on its mirror image by any combination of rotations, translations, and some conformational changes. This geometric property is called chirality (/ k aɪ ˈ r æ l ɪ t i /). The terms are derived from Ancient Greek χείρ (cheir) 'hand'; which is the canonical example of an …
