## Abstract The determination of the enantiomeric impurity, i.e., the percentage of (+) Nโ0437 (= Nโ0924) in several batches of (โโ) Nโ0437 (= Nโ0923) by chiral HPLC is described. Enantiomeric impurities were calculated based on the peak areas of the two baseline separated enantiomers in the chroma

The enantiomeric purities of both substrate, 2-acetoxy-3-bromopropyl para-toluenesulfonate (I), and product, 2-hydroxy-3-bromopropyl p-toluenesulfonate (11) were examined in one analysis. The enzymatic resolution was conducted by Amano lipase AK and the enantiomeric excess as well as the conversion
