摘要

Cyclodextrins (CDs) are the most frequently used chiral selectors in the capillary electrophoresis [1]. For academic research usually single isomer CDs are used, but for practical purposes the random substituted CDs give often suitable results especially when CD derivatives produced industrially are used. Sulfobutylether beta-CD (SBE-β-CD) is a pharmaceutical excipient in US Pharmacopoeia as solubilizing agent [2] and is a component of several drug formulations in the market. Its composition is strictly regulated therefore the average degree of substitution (DS) and the distribution of the components of various DS fall always in a narrow range. The standard quality results in high reproducibility for analytical applications.
