Novel chiral stationary phases, (1R,2S)- and diastereomeric (1S,2S)-2-carboxymethylamino-1,2-diphenylethanol, were prepared from (1R,2S)- and (1S,2S)-2-amino-1,2-diphenylethanol, respectively, and were bound to silica gel pretreated with 3-glycidoxypropyltrimethoxysilane. The chiral stationary phases were found to be very effective for the optical resolution of amino acids, amino acid derivatives and hydroxy acids by ligand-exchange high-performance liquid chromatography.

UI MeSH Term Description Entries
D008024 Ligands A molecule that binds to another molecule, used especially to refer to a small molecule that binds specifically to a larger molecule, e.g., an antigen binding to an antibody, a hormone or neurotransmitter binding to a receptor, or a substrate or allosteric effector binding to an enzyme. Ligands are also molecules that donate or accept a pair of electrons to form a coordinate covalent bond with the central metal atom of a coordination complex. (From Dorland, 27th ed) Ligand
