General description
CHIROBIOTIC® R, based on the ristocetin A glycopeptide covalently bonded to high purity silica particles, has shown particular applicability to enantiomers of anionic compounds. Selectivity on CHIROBIOTIC® R strongly correlates to the organic modifier, favoring the alcohol-type mobile phases by a large margin.

Application
- Sensitive Determination of Lactic Acid Isomers: The Astec® CHIROBIOTIC® R Chiral HPLC Column was crucial in a study by Henry H et al., where it facilitated the sensitive determination of D-lactic acid and L-lactic acid in urine using high-performance liquid chromatography-tandem mass spectrometry. This method is pivotal for clinical diagnostic applications, showcasing the column′s ability to resolve similar compounds that are challenging to differentiate by other means (Henry H et al., 2012).
- Enantioseparation of Cyclopentanecarboxylic and Cyclohexanecarboxylic Acids: The column was also utilized by Berkecz R et al. to achieve high-performance liquid chromatographic enantioseparation of complex 2-aminomono- and dihydroxycyclopentanecarboxylic and 2-aminodihydroxycyclohexanecarboxylic acids. This application underscores the column′s versatility and efficacy in separating closely related chiral acids, essential for biochemical research and pharmaceutical product development (Berkecz R et al., 2009).
