Chiral resolutions of (9‐anthryl)methoxyacetic acid and (9‐anthryl)hydroxyacetic acid by capillary electrophoresis

Abstract: The resolutions of (9-anthryl)methoxyacetic acid (9AMAA) and (9-anthryl)hydroxyacetic acid (9AHAA) were performed by capillary electrophoresis using hydroxypropyl-beta-cyclodextrin (HP-beta-CD) as a chiral selector. Various factors affecting migration time and resolutions of these compounds were investigated with a run voltage of 20 kV, column temperature 20 degrees C and 20 mM Tris-H(3)PO(4) buffer (pH 6.5) containing 5 mM HP-beta-CD for 9AMAA, or 10 mM HP-beta-CD for 9AHAA, (+/-)-9AMAA and (+/-)-9AHAA were s… Show more

“…Examples of commercially available randomly substituted CDs are neutral methylated CDs and 2‐hydroxypropylated CDs , and negatively charged carboxymethylated CDs and sulfated CDs . The only commercially available positively charged randomly substituted CD is quaternary ammonium β‐CD that has been used for the separation of negatively charged analytes .…”
