ANSWER

αobs=ee×αpure\alpha_{obs}=ee\times \alpha_{pure} (with eeee as a fraction). Observed rotation scales with the enantiomeric purity relative to the pure enantiomer's rotation.

Practice questions

1 of 50Practice questions for this set
A racemic drug is resolved by chiral HPLC into enantiomers E1 and E2. Only E1 is intended for clinical use. During stability testing at 37°C in aqueous buffer (pH 7.4), the isolated E1 sample shows a gradual decrease in optical rotation magnitude over 7 days, approaching zero, with no change in LC-MS mass. Based on these observations, which conclusion is most consistent with the results?
