Enantiomeric 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).

UnverifiedEnantiomeric excess (ee) is the core metric for quantitatively describing the purity of a chiral mixture, defined as the difference between the mole fractions of the two enantiomers divided by their sum; an ee of 0% represents a racemic mixture, and an ee of 100% represents complete single chirality.80% 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.80% similarPartially VerifiedEnantiomeric excess (ee value) is defined as the ratio of the difference between the concentrations of the two enantiomers to their sum, expressed as a percentage.75% similarUnverifiedIn the Soai reaction, even when the initial ee value is close to 0%, the ee value of the product can approach 100% after multiple rounds of autocatalytic cycling.73% similarUnverifiedEnantiomeric excess (ee) is the standard measure of chiral purity; if a product contains 90% right-handed and 10% left-handed forms, then ee = 80%.71% similar
