ReproSil Chiral-AM-R

Amylose-Based Chiral Phase for Enantioselective Reversed-Phase Chromatography

ReproSil Chiral-AM-R is a silica-based HPLC stationary phase coated with tris-(3,5-dimethylphenyl)carbamate amylose, specifically developed for enantioselective separations under reversed-phase conditions. This chiral amylose derivative enables multiple molecular interactions – such as hydrogen bonding, dipole–dipole, and π–π interactions – which result in excellent chiral recognition and high enantioselectivity for a wide variety of racemic compounds.

In contrast to the normal-phase version, ReproSil Chiral-AM-R is optimized for aqueous and polar mobile phases, providing high stability and reproducible retention under reversed-phase conditions. The phase is built on high-purity spherical silica, ensuring outstanding mechanical robustness and consistent performance even in gradient or high-pressure operation. ReproSil Chiral-AM-R is ideal for pharmaceutical, biochemical, and academic laboratories performing enantioselective analysis, method development, or quality control of chiral active ingredients and intermediates.

ReproSil Chiral-AM-R combines amylose-based chiral selectivity with reversed-phase compatibility – the dependable choice for efficient and reproducible enantioselective separations under aqueous chromatographic conditions.

Attractive alternative to CHIRALPAK® AD-RH (Daicel®).
