What is Chiral Purity?
The extent to which a chiral substance consists of a single enantiomer, usually reported as enantiomeric excess (ee) or as a percentage of the undesired enantiomer. It is measured by chiral HPLC, chiral GC or sometimes specific rotation. Chiral purity matters in pharmaceuticals because enantiomers can differ in activity and toxicity.
