Axially chiral trifluoromethylbenzimidazolylbenzoic acid (TBBA) was used as a chiral derivatization agent for the assignment of the absolute configuration of β-chiral primary alcohols. The structures varied from simple aliphatic alcohols to complex cyclic systems and highly substituted sugar derivatives. The NMR-based method was successfully implemented to evaluate 17 compounds and displayed ΔδPM values higher than 0.1 ppm in most cases, which makes TBBA superior to MTPA and MPA and comparable to 9-AMA.Amine-functionalized mesoporous sil
