Chiral separation is the process of separating enantiomers, which are mirror-image isomers of a molecule that cannot be superimposed onto each other. Enantiomers possess identical physical and chemical properties but exhibit different biological activities. Chiral separation is crucial in fields such as pharmaceuticals, agrochemicals, and fine chemicals, where the specific enantiomeric form of a molecule may have different effects or interactions in biological systems.
Chiral chromatography relies on the use of a chiral stationary phase, which is a solid or liquid material capable of differentiating between enantiomers. The chiral stationary phase interacts selectively with the enantiomers, leading to differences in their retention times or elution orders. This separation is based on the differences in their molecular interactions, such as stereoselective adsorption or formation of inclusion complexes.
