Summary
Sulfated cyclodextrins are versatile chiral selectors for capillary electrophoresis (CE), effectively separating diverse analytes. Their broad applicability and minimal optimization needs suggest a universal strategy for chiral compound separation.
Area of Science:
- Analytical Chemistry
- Separation Science
Background:
- Sulfated cyclodextrins have been used as enantioselective agents in capillary electrophoresis (CE) since 1995.
- These anionic additives exhibit broad applicability in separating chiral compounds.
Purpose of the Study:
- To review the role of sulfated cyclodextrins in chiral separations using CE.
- To explore their potential for a universal chiral separation strategy.
Main Methods:
- Review of literature on sulfated cyclodextrins in CE.
- Analysis of their structure, migration properties, and application universality.
Main Results:
- Successfully separated acidic, basic, neutral, and zwitterionic chiral compounds.
- Diverse compound classes including pharmaceuticals, plant extracts, and metal ions were analyzed.
- Minimal optimization is typically required for successful separations.
Conclusions:
- Sulfated cyclodextrins demonstrate remarkable versatility and effectiveness in chiral CE.
- They are well-suited for developing a universal and comprehensive chiral separation strategy.
