Description

CHIRALDEX™ B-DA requires that analytes possess a minimum of two ring structures, one of which is unsaturated (aromatic) alpha, beta to the stereogenic center. Examples include fluoxetine, methylphenidate and chloropheniramine.

Inclusion complexation or proper fit between the analyte and cyclodextrin cavity is the dominant enantioselectivity mechanism for the DA series. There must be an includable group alpha or beta to the stereogenic center for chiral recognition. Since CHIRALDEX™ DA columns most effectively separate multi-ring analytes, analysis temperatures are often higher than 150C. Enantioselectivity has been observed at temperatures >200°C (fluoxetine acetyl derivative).
