Enantiomeric discrimination of chiral secondary alcohols was performed by both reversed‐phase HPLC and 1 H‐NMR after labeling with a chiral fluorescent derivatization reagent, 2‐(2,3‐anthracenedicarboximide)cyclohexanecarboxylic acid. It was possible to discriminate by HPLC the chirality of alcohols up to C30 having a chiral hydroxyl group at the middle of the straight alkyl chain, and, by 1 H‐NMR, alcohols up to C16. For alcohols having one straight alkyl and one isoalkyl group with the same carbon numbers at both sides of a hydroxyl group, it was possible to discriminate the chiralities of alcohols up to C19 by both 1 H‐NMR and HPLC. The 1 H‐NMR methods also made it possible to determine absolute configurations empirically. Chirality 17:S171–S176, 2005. © 2005 Wiley‐Liss, Inc.
