Enantiomeric excess (ee value) is the core metric for measuring the efficiency of chiral synthesis; if the R-form accounts for 99.5% and the S-form accounts for 0.5%, the ee value is 99%.

UnverifiedEnantiomeric excess (ee) is the standard measure of chiral purity; if a product contains 90% right-handed and 10% left-handed forms, then ee = 80%.74% similarUnverifiedIn the Soai reaction, even if the initial chiral imbalance is less than 0.00005%, the enantiomeric excess (ee value) of the product can exceed 99.5% after multiple cycles.71% similarUnverifiedEnantiomeric excess (ee value): ee = 100% means the reaction produces only one enantiomer, while ee = 0% means the two enantiomers are present in equal amounts (a racemic mixture).69% similarUnverifiedIn the Artificial Analysis composite index, Opus 5.5 scored 58, Sol scored 48, and Luna scored 37.69% similarUnverifiedThe overall agent efficiency score proposed by Bland consists of a funnel model composed of three progressively layered ratios: autonomous completion rate, token efficiency ratio, and value generation ratio.68% similar
