Fisher first reported its use as a resolving agent in 1899, and it was the first natural product used as an organocatalyst in a reaction resulting in a successful enantiomeric enrichment by Marckwald, in 1904.[7] Its bromide salt has been used as the stationary phase in HPLC in order to selectively bind one of two anionic enantiomers.[8] Brucine has also been used in fractional distillation in acetone in order to resolve dihydroxy fatty acids,[9] as well as diarylcarbinols.[10]
