Merck, 16023AST, Astec® CHIROBIOTIC® T2 Chiral HPLC Column

General description
CHIROBIOTIC® T and T2 have teicoplanin as the chiral selector. They offer unique selectivity for a number of classes of molecules, specifically underivatized α, β, γ and cyclic amino acids, N-derivatized amino acids, hydroxy-carboxylic acids, acidic compounds including carboxylic acids and phenols, small peptides, neutral aromatic analytes and cyclic aromatic and aliphatic amines. Separations normally obtained on a chiral crown ether or ligand exchange-type CSPs are also possible on the CHIROBIOTIC® T and T2, but in much simpler mobile phases, like water-alcohol. In addition, all of the known beta-blockers (amino alcohols), and dihydrocoumarins have been resolved. CHIROBIOTIC® T and T2 differ in their bonding chemistry and the pore size of the support particle, giving them different selectivity and preparative capacity.

Bonded phase: Teicoplanin
Operating pH range: 3.8 - 6.8
Particle diameter: 5, 10 or 16 μm
Pore size: 100 Å (CHIROBIOTIC® T) or 200 Å (CHIROBIOTIC® T2)

Application

High-performance liquid chromatographic enantioseparation of 2-aminomono- and dihydroxycyclopentanecarboxylic and 2-aminodihydroxycyclohexanecarboxylic acids on macrocyclic glycopeptide-based phases.: This research employs the Astec® CHIROBIOTIC T2 Chiral HPLC Column for the enantioseparation of various amino acids. The study highlights the column′s effectiveness in separating complex chiral molecules, demonstrating its application in the analysis of amino acids and related compounds in chemical and pharmaceutical research (Berkecz et al., 2009).
