Descrizione generale
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

- Particle diameter: 5, 10 or 16 μm

A high performance liquid chromatographic method using macrocyclic glycopeptide chiral stationary phases (CSPs) was used to separate enantiomers of seven ruthenium(II) polypyridyl complexes. Among the five different CSPs, the Chirobiotic T2 was most effective and baseline separated all complexes. All

A rapid screening method to identify the best conditions for chiral separations is described. We analyzed a representative set of 80 racemic compounds against 25 different chiral stationary phases with three different mobile phases to identify the combination of columns

The enantioselective separations of the chiral oxazaphosphorines (R,S)-ifosfamide (IF), (R,S)-2-N-dechloroethyl-IF (2-DCE-IF) and (R,S)-3-N-dechloroethyl-IF (3-DCE-IF) were achieved on teicoplanin-based chiral stationary phase using isopropanol:methanol (60:40, v/v) as the mobile phase. Computational models of the teicoplanin and teicoplanin aglycon (TAG) chiral selectors
